1
00:00:00,280 --> 00:00:02,840
Speaker 1: Brought to you by the reinvented two thousand twelve camera.

2
00:00:03,160 --> 00:00:08,920
Speaker 1: It's ready. Are you get in touch with technology? With

3
00:00:09,039 --> 00:00:17,960
Speaker 1: tech Stuff from how stuff works dot com. Hello again, everyone,

4
00:00:17,960 --> 00:00:20,160
Speaker 1: and welcome to tech stuff. My name is Chris Poulett,

5
00:00:20,160 --> 00:00:22,360
Speaker 1: and I'm an editor at how stuff works dot com.

6
00:00:22,360 --> 00:00:25,280
Speaker 1: Sitting across from me as usual as senior writer Jonathan Strickland.

7
00:00:25,560 --> 00:00:30,720
Speaker 1: No disassemble A nice thank you. I don't usually play

8
00:00:30,760 --> 00:00:33,919
Speaker 1: the quote game, but today's episode is one I've quoted

9
00:00:34,120 --> 00:00:37,600
Speaker 1: from in the past. The box is locked, the lights

10
00:00:37,600 --> 00:00:40,879
Speaker 1: are on. It's robot fighting time, right and uh, and

11
00:00:40,960 --> 00:00:46,080
Speaker 1: we're doing this because of a little Facebook feedback from

12
00:00:46,159 --> 00:00:50,400
Speaker 1: Corey who says, please do a podcast about battle butts

13
00:00:51,040 --> 00:00:55,640
Speaker 1: and now we will. All right then, Actually, the battle

14
00:00:55,680 --> 00:01:01,000
Speaker 1: bots is but one form of robot competition. Um. As

15
00:01:01,000 --> 00:01:02,640
Speaker 1: a matter of fact, there there are many different kinds

16
00:01:02,640 --> 00:01:05,920
Speaker 1: of competition overall. Now, uh, you might be thinking of

17
00:01:06,280 --> 00:01:10,160
Speaker 1: a first which is a different type of robot competition

18
00:01:10,160 --> 00:01:12,360
Speaker 1: in which you build robots that are supposed to solve

19
00:01:12,440 --> 00:01:17,400
Speaker 1: specific projects. It's uh an educational I think of anyway.

20
00:01:17,400 --> 00:01:21,040
Speaker 1: I think of it as an educational robot contest on

21
00:01:21,160 --> 00:01:23,720
Speaker 1: which you are trying to do something constructive with your robot, right,

22
00:01:23,720 --> 00:01:26,880
Speaker 1: Dean Kaman is involved with that one exactly, is exactly

23
00:01:26,920 --> 00:01:28,200
Speaker 1: and I think as a matter of fact, I think

24
00:01:28,240 --> 00:01:31,119
Speaker 1: there is an episode of stuff from the Science Lab

25
00:01:31,520 --> 00:01:34,040
Speaker 1: from a long time ago that may have focused on

26
00:01:34,040 --> 00:01:37,800
Speaker 1: on that. Yeah. Actually they did a visit to first

27
00:01:37,840 --> 00:01:40,480
Speaker 1: to the robot competition because that they tend to take

28
00:01:40,520 --> 00:01:43,080
Speaker 1: place in Georgia. Now, you know, this is one of

29
00:01:43,080 --> 00:01:45,520
Speaker 1: the things that I like about you know, Lego, you

30
00:01:45,840 --> 00:01:48,120
Speaker 1: build these massive things, you can build them in all

31
00:01:48,160 --> 00:01:51,160
Speaker 1: different kinds of configurations, and robots are are similar in

32
00:01:51,160 --> 00:01:52,800
Speaker 1: that you can do all kinds of things. You can

33
00:01:52,840 --> 00:01:55,040
Speaker 1: have them lift things, you can have them move and

34
00:01:55,040 --> 00:02:00,760
Speaker 1: and grapple, and then as with many of my Lego toys,

35
00:02:01,280 --> 00:02:04,000
Speaker 1: you can also bust them into many, many little pieces.

36
00:02:05,400 --> 00:02:11,520
Speaker 1: And that's what battle bots is and it's smash yes. Um.

37
00:02:11,600 --> 00:02:16,680
Speaker 1: The uh, the whole concept is sometimes i would say

38
00:02:16,840 --> 00:02:22,200
Speaker 1: probably mostly attributed to a guy named Mark Thorpe who

39
00:02:22,520 --> 00:02:28,359
Speaker 1: he actually was working for Mr George Lucas UM. He

40
00:02:28,480 --> 00:02:31,880
Speaker 1: was a senior designer for Lucas Toys. Uh, and at

41
00:02:31,919 --> 00:02:34,000
Speaker 1: that point he was he came up with the idea

42
00:02:34,040 --> 00:02:38,840
Speaker 1: of fighting vehicles. UM. You know, basically he was surprised.

43
00:02:39,000 --> 00:02:41,040
Speaker 1: I went to his website in researching this, and he

44
00:02:41,040 --> 00:02:43,520
Speaker 1: said that he was surprised that people seemed sort of

45
00:02:43,520 --> 00:02:46,760
Speaker 1: indifferent to it. And he said, you know what, somebody's

46
00:02:46,760 --> 00:02:49,200
Speaker 1: going to figure out how this is gonna work. In fact,

47
00:02:49,240 --> 00:02:52,400
Speaker 1: that was almost a verbatim direct quote um. But he

48
00:02:52,480 --> 00:02:55,880
Speaker 1: also was thinking about the possibility of creating a radio

49
00:02:55,960 --> 00:03:00,400
Speaker 1: controlled vacuum cleaner. Can you imagine that a robotic vacuum cleaner?

50
00:03:03,040 --> 00:03:07,359
Speaker 1: Uh The idea would be too make it an enjoyable process.

51
00:03:07,840 --> 00:03:11,880
Speaker 1: Mr Thorpe said, Uh. So he started thinking about the

52
00:03:11,960 --> 00:03:15,040
Speaker 1: idea as he was taking is one of his uh

53
00:03:15,160 --> 00:03:19,600
Speaker 1: um inventions apart and said, wait a minute, what if

54
00:03:19,639 --> 00:03:23,680
Speaker 1: I put you know, tools of destruction on this, and

55
00:03:23,720 --> 00:03:28,800
Speaker 1: we we had these robotic remote controlled robots and acume

56
00:03:28,919 --> 00:03:36,520
Speaker 1: cleaner of death. Well yeah, more or less. So essentially

57
00:03:36,680 --> 00:03:41,640
Speaker 1: that's how robot Wars was created. Came up with the

58
00:03:41,680 --> 00:03:44,280
Speaker 1: idea of having a robotic competition which you would build

59
00:03:44,560 --> 00:03:48,240
Speaker 1: remote controlled devices that would attempt to destroy one another

60
00:03:48,280 --> 00:03:51,600
Speaker 1: in an arena. Uh and the arena that's arena itself

61
00:03:51,600 --> 00:03:54,560
Speaker 1: would also be trying to destroy the two robots, so

62
00:03:54,600 --> 00:03:58,440
Speaker 1: there would be obstacles in play, and you could either

63
00:03:59,000 --> 00:04:04,400
Speaker 1: fall prey to them or perhaps manipulate your opponent so that, yes,

64
00:04:04,480 --> 00:04:10,480
Speaker 1: it would become a jumble of of garbage. Yes, UM,

65
00:04:10,520 --> 00:04:16,520
Speaker 1: this was. This started happening around UM and at the

66
00:04:16,600 --> 00:04:21,080
Speaker 1: time you know it launched, it was let's say this

67
00:04:21,160 --> 00:04:23,400
Speaker 1: qualified to the people who would actually want to watch

68
00:04:23,440 --> 00:04:28,160
Speaker 1: something like this a smashing success, no pun intended for once, UM,

69
00:04:28,360 --> 00:04:32,120
Speaker 1: because sometimes it was a flipping success exactly. But yeah,

70
00:04:32,279 --> 00:04:36,000
Speaker 1: it took off, the idea, took off the problem with

71
00:04:36,600 --> 00:04:38,120
Speaker 1: robot wars. And I don't want to get into this

72
00:04:38,160 --> 00:04:40,560
Speaker 1: in lots of detail because I don't know all the

73
00:04:40,880 --> 00:04:46,159
Speaker 1: mechanisms of this. UM. Mr Thorpe worked with a company

74
00:04:46,200 --> 00:04:50,599
Speaker 1: in New York, record company UH to help him finance it.

75
00:04:51,160 --> 00:04:57,240
Speaker 1: The company UM was named Profile and UH Profile Records

76
00:04:57,240 --> 00:05:02,800
Speaker 1: at that point, and apparently after some time there were

77
00:05:03,000 --> 00:05:08,040
Speaker 1: some grappling over the rights to the name and the concept. UH.

78
00:05:08,120 --> 00:05:11,039
Speaker 1: And by that point, you know, I don't wanted to

79
00:05:11,080 --> 00:05:14,039
Speaker 1: skip ahead UH in in a great but this is

80
00:05:14,040 --> 00:05:16,120
Speaker 1: not really a history podcast because we're actually going to

81
00:05:16,200 --> 00:05:18,800
Speaker 1: talk about that UM as the thing is. By that

82
00:05:19,000 --> 00:05:21,280
Speaker 1: by the point where it really got to be a

83
00:05:21,320 --> 00:05:24,520
Speaker 1: serious fight, and we're talking like lawyers are getting involved

84
00:05:24,520 --> 00:05:28,720
Speaker 1: with this enough people were involved with the idea that

85
00:05:28,800 --> 00:05:31,520
Speaker 1: they it sort of took off and other people became

86
00:05:31,560 --> 00:05:34,839
Speaker 1: involved with it, and that's where, you know, some of

87
00:05:34,839 --> 00:05:38,280
Speaker 1: the fans broke off and started their own U league,

88
00:05:39,360 --> 00:05:41,520
Speaker 1: which is now known as battle Bots. Yeah. They had

89
00:05:41,520 --> 00:05:44,599
Speaker 1: become disenchanted with Robot Wars just because of all the

90
00:05:44,680 --> 00:05:47,360
Speaker 1: legal wrangling and UH there was there was there was

91
00:05:47,360 --> 00:05:50,120
Speaker 1: an effort to bring it to UH, to England as

92
00:05:50,160 --> 00:05:53,160
Speaker 1: a television show, which eventually did happen and was very

93
00:05:53,160 --> 00:05:56,800
Speaker 1: successful there than some shows in the United States as well,

94
00:05:56,800 --> 00:06:00,320
Speaker 1: with the United States cast that also were you know,

95
00:06:00,360 --> 00:06:05,320
Speaker 1: followed under the Robot Wars name. But some people during

96
00:06:05,360 --> 00:06:09,680
Speaker 1: this this UH period of turmoil, they just felt like

97
00:06:09,880 --> 00:06:12,359
Speaker 1: they felt like they were being overlooked. They felt like,

98
00:06:12,400 --> 00:06:15,040
Speaker 1: you know, this was supposed to be just about engineers

99
00:06:15,040 --> 00:06:18,839
Speaker 1: and robots specialist building machines and having them compete, and

100
00:06:18,880 --> 00:06:21,200
Speaker 1: it's kind of all getting lost in this legal shuffle.

101
00:06:21,279 --> 00:06:23,960
Speaker 1: So they sort of formed a splinter group and split

102
00:06:24,000 --> 00:06:25,840
Speaker 1: off from there, and that's that was kind of the

103
00:06:25,920 --> 00:06:29,840
Speaker 1: genesis of battle Bots. Ye. And UH, of course, the

104
00:06:29,839 --> 00:06:32,920
Speaker 1: the the people who were in charge of robot Wars

105
00:06:32,920 --> 00:06:36,320
Speaker 1: sued the people who were in charge of battle bots. Um.

106
00:06:36,440 --> 00:06:40,240
Speaker 1: But as as time went on, battle bots sort of

107
00:06:40,279 --> 00:06:43,279
Speaker 1: came to be the primary competition in the United States,

108
00:06:43,279 --> 00:06:49,280
Speaker 1: and robot wars had moved overseas to the United Kingdom. Um.

109
00:06:49,440 --> 00:06:52,720
Speaker 1: And you know the thing is this probably would have

110
00:06:52,760 --> 00:06:56,720
Speaker 1: passed in relative obscurity for people who really like robots,

111
00:06:57,320 --> 00:07:01,720
Speaker 1: but um, in the United States, they and televising BattleBots

112
00:07:01,760 --> 00:07:06,000
Speaker 1: competition on the Honest Channel possible. Well, you know, there

113
00:07:06,000 --> 00:07:07,480
Speaker 1: are a lot of things that have come out of

114
00:07:07,720 --> 00:07:11,480
Speaker 1: Comedy Central that you might not have expected. Yeah, but

115
00:07:11,600 --> 00:07:15,680
Speaker 1: you know, robots fighting each other, and you know, we

116
00:07:15,680 --> 00:07:19,080
Speaker 1: we should say here if you have never seen battle bots,

117
00:07:20,160 --> 00:07:22,040
Speaker 1: when you hear robots fighting each other, you may be

118
00:07:22,120 --> 00:07:27,480
Speaker 1: thinking of because yeah, like humanoid type robots, robots that

119
00:07:27,520 --> 00:07:30,880
Speaker 1: have an anthropomorphic type shape. Uh, that's not the case.

120
00:07:30,920 --> 00:07:33,240
Speaker 1: Some of these robots were quite odd. A lot of

121
00:07:33,240 --> 00:07:36,320
Speaker 1: them look like boxes with wheels, um. And in fact,

122
00:07:36,320 --> 00:07:38,560
Speaker 1: a lot of them that's essentially what their their basic

123
00:07:38,640 --> 00:07:44,040
Speaker 1: form factor was. But you know, it's there was nothing

124
00:07:44,360 --> 00:07:49,000
Speaker 1: inherently comedic, although of course the the play by play

125
00:07:49,080 --> 00:07:53,480
Speaker 1: announcers and the behavior of the crowds could sometimes lend

126
00:07:53,560 --> 00:07:56,600
Speaker 1: a slight comedic air to the proceedings, but it wasn't

127
00:07:56,680 --> 00:07:58,600
Speaker 1: you know, you wouldn't call it a comedy. It was

128
00:07:58,640 --> 00:08:02,200
Speaker 1: a competition, no, no, but it was certainly a lighthearted competition.

129
00:08:02,240 --> 00:08:05,480
Speaker 1: No one, no person or was getting hurt, at least

130
00:08:05,480 --> 00:08:09,000
Speaker 1: not in the arena. Feelings might be heard, certainly, Oh,

131
00:08:09,040 --> 00:08:10,760
Speaker 1: I'm sure there was more than a little bit of that.

132
00:08:10,880 --> 00:08:13,000
Speaker 1: But yes, for for a few brief years here in

133
00:08:13,000 --> 00:08:15,960
Speaker 1: the United States in the early two thousand's and I

134
00:08:16,080 --> 00:08:20,000
Speaker 1: guess technically stretching back to Maybee, but really in the

135
00:08:20,080 --> 00:08:23,120
Speaker 1: early two thousand's, UM, there were a few seasons of

136
00:08:23,160 --> 00:08:26,800
Speaker 1: battle Bots, which I recorded on my DVR and watched

137
00:08:27,400 --> 00:08:29,760
Speaker 1: as far as I know, every episode of and was

138
00:08:29,880 --> 00:08:31,920
Speaker 1: very sorry to see that they canceled it, and I

139
00:08:31,960 --> 00:08:36,720
Speaker 1: was a little concerned that it might disappear. UM actually

140
00:08:36,840 --> 00:08:40,520
Speaker 1: was talking with a friend about the possibility of creating

141
00:08:40,520 --> 00:08:43,480
Speaker 1: a battle bot. As it turned out that we uh

142
00:08:43,640 --> 00:08:48,440
Speaker 1: didn't get very far with that because creating a battle

143
00:08:48,480 --> 00:08:51,600
Speaker 1: bot a robot to do this, we're not talking about, uh,

144
00:08:51,640 --> 00:08:54,480
Speaker 1: you know, something like the Lego mind Storms that would

145
00:08:54,480 --> 00:08:57,120
Speaker 1: be kind of fun too, Whether those would last very

146
00:08:57,120 --> 00:08:59,959
Speaker 1: long in a battle, not in in this particular kind

147
00:09:00,000 --> 00:09:04,200
Speaker 1: of arena, because we're talking about things with spikes and

148
00:09:04,480 --> 00:09:09,480
Speaker 1: buzz saws and ramps, ramps and flying metal, some of

149
00:09:09,520 --> 00:09:12,720
Speaker 1: which gets very very heavy. Uh. It takes a lot

150
00:09:12,760 --> 00:09:20,440
Speaker 1: of pneumatics, UM, heavy duty motors, hydraulics, cydraulics, UM. These

151
00:09:20,480 --> 00:09:23,240
Speaker 1: these tools are very heavy and can do a lot

152
00:09:23,280 --> 00:09:25,240
Speaker 1: of damage to people, which is why the arena is

153
00:09:25,280 --> 00:09:29,640
Speaker 1: completely enclosed. UM, we're not talking about just the sides.

154
00:09:29,640 --> 00:09:31,920
Speaker 1: There's not it's it's not like you might see at

155
00:09:32,000 --> 00:09:34,880
Speaker 1: a race where there's a fence to a certain part,

156
00:09:34,960 --> 00:09:37,640
Speaker 1: but otherwise it's not enclosed. This is in a basically

157
00:09:37,640 --> 00:09:42,360
Speaker 1: in a square box a cage, so before they before

158
00:09:42,360 --> 00:09:46,480
Speaker 1: they compete. Um. So the thing is, though, these are

159
00:09:46,600 --> 00:09:48,920
Speaker 1: very expensive because not only do you build your body,

160
00:09:49,520 --> 00:09:53,880
Speaker 1: you also have to maintain the bot. Say you get

161
00:09:53,920 --> 00:09:57,160
Speaker 1: in this is this is an a tournament format. This competition,

162
00:09:57,240 --> 00:09:59,839
Speaker 1: so you have many rounds of competition. So you get

163
00:09:59,840 --> 00:10:04,439
Speaker 1: a first round match and you are competing against another

164
00:10:04,559 --> 00:10:08,280
Speaker 1: robot with your robot. Let's say you're successful or you know,

165
00:10:08,720 --> 00:10:11,240
Speaker 1: the person's motor the remote control never works, or the

166
00:10:11,480 --> 00:10:13,520
Speaker 1: you know, battery burns out, let's say you are you

167
00:10:13,559 --> 00:10:16,120
Speaker 1: do actually work, and you go against one another. Well,

168
00:10:16,559 --> 00:10:19,880
Speaker 1: the other guy, the other guy's robot tore part of

169
00:10:20,160 --> 00:10:23,000
Speaker 1: the skin of your robot off with the buzz saw

170
00:10:23,040 --> 00:10:25,800
Speaker 1: that's attached to the robot. Well, now you have a

171
00:10:25,840 --> 00:10:27,480
Speaker 1: second round match. What are you gonna do? Well, you

172
00:10:27,520 --> 00:10:30,200
Speaker 1: have to refurbish that. Well, let's say the the hammer

173
00:10:30,240 --> 00:10:32,720
Speaker 1: on the top of your robot with the spike that

174
00:10:32,720 --> 00:10:34,800
Speaker 1: that pierces the arm or the other one and carries

175
00:10:34,800 --> 00:10:40,440
Speaker 1: it into the buzz saw that's in the the arena floor. Um, well,

176
00:10:40,600 --> 00:10:43,800
Speaker 1: you know the thing is it got stuck and the

177
00:10:43,840 --> 00:10:46,360
Speaker 1: motor burned out or if they're gonna have to replace it. Well,

178
00:10:46,400 --> 00:10:50,880
Speaker 1: this is expensive stuff you can't just jump in with, right,

179
00:10:51,000 --> 00:10:52,800
Speaker 1: I mean, and when you've got things like pneumatics and

180
00:10:52,880 --> 00:10:56,440
Speaker 1: hydraulics that may potentially be powering part of your robot,

181
00:10:56,440 --> 00:10:59,000
Speaker 1: You've got lots of tubes that can suffer damage, and

182
00:10:59,480 --> 00:11:02,000
Speaker 1: if there's a leak, then clearly your robot's not going

183
00:11:02,040 --> 00:11:05,079
Speaker 1: to perform up to what the standard was before and

184
00:11:05,480 --> 00:11:08,439
Speaker 1: you need to replace that in the middle. And yeah,

185
00:11:08,720 --> 00:11:10,920
Speaker 1: it can be very expensive. And it's not like there

186
00:11:10,920 --> 00:11:14,320
Speaker 1: are a lot of off the shelf parts for these robots,

187
00:11:14,360 --> 00:11:17,000
Speaker 1: although there are companies that are that kind of catered

188
00:11:17,040 --> 00:11:20,080
Speaker 1: to this this uh, this hobby now, and there are

189
00:11:20,120 --> 00:11:23,000
Speaker 1: some places where you can buy stuff that has been

190
00:11:23,040 --> 00:11:27,120
Speaker 1: specifically geared for use with robots. But especially in the

191
00:11:27,120 --> 00:11:29,559
Speaker 1: early days, this was a lot of do it yourself,

192
00:11:29,600 --> 00:11:33,240
Speaker 1: you know, building, taking various pieces from hardware stores and

193
00:11:33,360 --> 00:11:37,079
Speaker 1: motors and and RF controllers and that kind of thing

194
00:11:37,160 --> 00:11:40,160
Speaker 1: and making it all work together. Now it's really a

195
00:11:40,200 --> 00:11:42,679
Speaker 1: feat of engineering to build one of these things. Yes,

196
00:11:42,720 --> 00:11:44,480
Speaker 1: and it doesn't help to have a machine shop at

197
00:11:44,480 --> 00:11:47,240
Speaker 1: your disposal. So if you can't find the pieces that

198
00:11:47,280 --> 00:11:49,640
Speaker 1: you need, you can make them. Yeah, you can make

199
00:11:49,640 --> 00:11:53,760
Speaker 1: a custom built robot. Well they're all custom built, but

200
00:11:53,920 --> 00:11:56,000
Speaker 1: you can make one where it has unique parts that

201
00:11:56,080 --> 00:11:59,560
Speaker 1: you would not find anywhere else. So let's talk about

202
00:11:59,559 --> 00:12:03,040
Speaker 1: the competition as in itself. Sure, because I'm sorry, Oh no,

203
00:12:03,080 --> 00:12:06,240
Speaker 1: go ahead. So so let's say you you do have

204
00:12:06,320 --> 00:12:08,959
Speaker 1: a few thousand sitting around you want to go ahead

205
00:12:08,960 --> 00:12:11,960
Speaker 1: and give it a try. Um, first of all, it

206
00:12:11,960 --> 00:12:14,280
Speaker 1: would help to go to the battle bots website to

207
00:12:14,360 --> 00:12:16,840
Speaker 1: learn more about the competition. Now, on the on the website,

208
00:12:16,840 --> 00:12:18,840
Speaker 1: you'll find the rules that you need to adhere to

209
00:12:18,920 --> 00:12:22,080
Speaker 1: It's not anything goes. You really have to abide by

210
00:12:22,080 --> 00:12:26,280
Speaker 1: a certain set of rules of those specifications. Yep. So, uh,

211
00:12:26,320 --> 00:12:28,400
Speaker 1: you need to find out what's going on. You need

212
00:12:28,440 --> 00:12:30,080
Speaker 1: to find out when the competitions are going to be.

213
00:12:30,120 --> 00:12:32,800
Speaker 1: It would help to become immersed in the community, learn

214
00:12:32,840 --> 00:12:35,200
Speaker 1: a little bit more about Maybe there's a regional competition

215
00:12:35,240 --> 00:12:37,640
Speaker 1: you could go to to try your robot out, and

216
00:12:37,640 --> 00:12:39,439
Speaker 1: then you need to start thinking about the kind of

217
00:12:39,520 --> 00:12:44,640
Speaker 1: robot you want to build. UM. But let's sticking with

218
00:12:44,679 --> 00:12:47,480
Speaker 1: the competition. So you go to a competition and there

219
00:12:47,520 --> 00:12:50,760
Speaker 1: are several rounds. You're given a pit area sort of

220
00:12:50,760 --> 00:12:52,600
Speaker 1: like a race car might at a at a race,

221
00:12:53,200 --> 00:12:55,160
Speaker 1: where you can set up your shops. So you've got

222
00:12:55,160 --> 00:12:58,400
Speaker 1: all your parts for your robot. You've got your robot itself. Uh.

223
00:12:58,400 --> 00:13:00,320
Speaker 1: This gives you a place to put your tools in

224
00:13:00,360 --> 00:13:05,760
Speaker 1: your parts and do any necessary maintenance or tuning or UH.

225
00:13:05,840 --> 00:13:09,160
Speaker 1: If you've got a switch that goes from mayme to kill,

226
00:13:09,679 --> 00:13:13,120
Speaker 1: this is where you flip that switch and and you

227
00:13:13,120 --> 00:13:15,400
Speaker 1: you are allowed to have a pit crew. Though your

228
00:13:15,400 --> 00:13:18,559
Speaker 1: pit crew has to be a certain size. UM. You know,

229
00:13:18,960 --> 00:13:22,240
Speaker 1: there's no size limit on the team that uh, that

230
00:13:22,280 --> 00:13:24,760
Speaker 1: you used to build your robot. In fact, you can

231
00:13:24,800 --> 00:13:26,520
Speaker 1: have a team of one if you like, yeah, or

232
00:13:26,600 --> 00:13:30,079
Speaker 1: you could have a team of an entire campus if

233
00:13:30,120 --> 00:13:33,320
Speaker 1: you really want to college campus, it could be that big.

234
00:13:33,640 --> 00:13:37,280
Speaker 1: But your pit crew, of course cannot be big. Now

235
00:13:37,440 --> 00:13:40,600
Speaker 1: there are several divisions. Um there's a high school division,

236
00:13:40,600 --> 00:13:43,200
Speaker 1: in a college division, and the pro division, which is

237
00:13:43,360 --> 00:13:46,240
Speaker 1: I don't think necessarily you're a professional robot builder, but

238
00:13:46,320 --> 00:13:49,480
Speaker 1: I think they mean any age group, right, and uh,

239
00:13:49,559 --> 00:13:52,320
Speaker 1: you can you can even get sponsorships, which helps for

240
00:13:52,400 --> 00:13:54,840
Speaker 1: that expensive part of the game of playing this game.

241
00:13:55,280 --> 00:14:00,280
Speaker 1: There are two basic variations on robots recognized in battle Bots.

242
00:14:00,840 --> 00:14:04,400
Speaker 1: There are non walking robots, so essentially anything that uses

243
00:14:04,400 --> 00:14:07,559
Speaker 1: wheels or treadmills, that kind of thing treads or snakes

244
00:14:07,600 --> 00:14:11,040
Speaker 1: along the four snakes along the floor. Yeah, anything that

245
00:14:11,320 --> 00:14:13,760
Speaker 1: is not is not actually lifting a leg and putting

246
00:14:13,760 --> 00:14:16,640
Speaker 1: it down in order to move, uh, that is considered

247
00:14:16,640 --> 00:14:20,920
Speaker 1: a non walking robot. And the weight designations for those um.

248
00:14:21,240 --> 00:14:23,560
Speaker 1: And if you are competing at the high school or

249
00:14:23,640 --> 00:14:27,600
Speaker 1: college level, your non walking robot can weigh a maximum

250
00:14:27,680 --> 00:14:30,840
Speaker 1: of one pounds. If you're a professional, that goes up

251
00:14:30,880 --> 00:14:35,240
Speaker 1: to two hundred twenty pounds, so the walking robots also

252
00:14:35,280 --> 00:14:39,400
Speaker 1: called stop butts, uh those that they can get a

253
00:14:39,400 --> 00:14:43,800
Speaker 1: little heavier, So in high school or college competitions it

254
00:14:43,880 --> 00:14:46,400
Speaker 1: can be up to a hundred sixty pounds and for

255
00:14:46,440 --> 00:14:49,800
Speaker 1: a professional whopping three hundred pounds, So you can have

256
00:14:49,880 --> 00:14:53,200
Speaker 1: a three hundred pounds stomp robot if you are competing

257
00:14:53,280 --> 00:14:58,400
Speaker 1: on a professional battle bots team. Now and a little scary.

258
00:14:58,720 --> 00:15:01,560
Speaker 1: The the whole goal here, I mean we we've alluded

259
00:15:01,600 --> 00:15:03,120
Speaker 1: to it quite a bit, but the whole goal here

260
00:15:03,160 --> 00:15:06,160
Speaker 1: is that you you face off against an opponent. You

261
00:15:06,160 --> 00:15:09,040
Speaker 1: know it's been in both cases. Your your robot is

262
00:15:09,440 --> 00:15:14,480
Speaker 1: normally controlled by remote controls. Normally you would you would

263
00:15:14,520 --> 00:15:17,240
Speaker 1: be under you know, each robot would be under human control,

264
00:15:17,560 --> 00:15:19,960
Speaker 1: although there are rules for autonomous robots which we'll talk

265
00:15:19,960 --> 00:15:22,280
Speaker 1: about in the second and they're pretty fun. But the

266
00:15:22,320 --> 00:15:24,800
Speaker 1: idea here is that you go into a competition. There's

267
00:15:24,800 --> 00:15:29,320
Speaker 1: a set amount of time for the round, and your

268
00:15:29,360 --> 00:15:33,560
Speaker 1: goal is to disable the other robot within that time,

269
00:15:34,280 --> 00:15:38,840
Speaker 1: or to inflict more damage or show better strategy. You know,

270
00:15:38,920 --> 00:15:41,280
Speaker 1: your your your rounds are you The round is judged

271
00:15:41,280 --> 00:15:44,120
Speaker 1: on various criteria like how much damage did you inflict,

272
00:15:44,280 --> 00:15:46,960
Speaker 1: how much damage damage did you receive, and what was

273
00:15:46,960 --> 00:15:49,040
Speaker 1: your you know, how strategic was your attack. If you

274
00:15:49,080 --> 00:15:50,840
Speaker 1: were running away the whole time, you're not gonna be

275
00:15:50,920 --> 00:15:54,880
Speaker 1: judged very well. But if you if you are able

276
00:15:54,920 --> 00:15:58,120
Speaker 1: to disable the other robot, or you inflict more damage

277
00:15:58,160 --> 00:16:00,800
Speaker 1: and play a better game than the other team, then

278
00:16:00,840 --> 00:16:05,200
Speaker 1: you would go on to the next round. So, uh,

279
00:16:05,240 --> 00:16:09,600
Speaker 1: that's that's the general idea. Now we can get down

280
00:16:09,640 --> 00:16:14,840
Speaker 1: into some more specifics, like what what constitutes your you know,

281
00:16:15,160 --> 00:16:18,440
Speaker 1: your robots weaponry. There were some robots that the weapon

282
00:16:18,560 --> 00:16:21,320
Speaker 1: was essentially the fact that the robot itself was shaped

283
00:16:21,320 --> 00:16:25,720
Speaker 1: like a ramp. It was designed to scoot under the

284
00:16:25,880 --> 00:16:29,000
Speaker 1: opposing robot and flip it over in the hopes that

285
00:16:29,040 --> 00:16:31,600
Speaker 1: by turning a robot upside down you have rendered it

286
00:16:31,840 --> 00:16:36,440
Speaker 1: useless because it wasn't designed to move upside down. Uh.

287
00:16:36,520 --> 00:16:38,840
Speaker 1: And then that we saw a lot of robots early

288
00:16:38,880 --> 00:16:40,800
Speaker 1: on that that was the basic design. It was just

289
00:16:40,960 --> 00:16:43,720
Speaker 1: essentially a ramp. It might have a little wheel or

290
00:16:43,840 --> 00:16:46,960
Speaker 1: a treadmill on the ramp to help propel the robot

291
00:16:47,040 --> 00:16:50,160
Speaker 1: over it, you know, the the opposing robot over it,

292
00:16:50,200 --> 00:16:52,760
Speaker 1: so it can flip it over and then we saw

293
00:16:52,760 --> 00:16:55,640
Speaker 1: a lot of robots pop up that could work either

294
00:16:55,760 --> 00:16:58,920
Speaker 1: right side up or upside down. So you know that

295
00:16:58,920 --> 00:17:02,760
Speaker 1: that weapon is a useless but you're supposed to have

296
00:17:02,840 --> 00:17:05,639
Speaker 1: some sort of weapon, right, That's right, that's it's a

297
00:17:05,680 --> 00:17:10,000
Speaker 1: requirement that you do have at least one active weapon

298
00:17:10,800 --> 00:17:13,879
Speaker 1: on on your body, and you can you can participate

299
00:17:14,040 --> 00:17:17,640
Speaker 1: even if your weapon is disabled. I mean you could

300
00:17:17,640 --> 00:17:19,320
Speaker 1: have a giant spike on the front of it and

301
00:17:19,320 --> 00:17:23,399
Speaker 1: that that counts. Uh. But say you have a you know,

302
00:17:23,440 --> 00:17:27,120
Speaker 1: an arm on your your bot and it doesn't move anymore,

303
00:17:27,600 --> 00:17:30,200
Speaker 1: but you move on and you can't get it repaired. Well,

304
00:17:30,560 --> 00:17:32,679
Speaker 1: as long as you still have the weapon attached to

305
00:17:32,720 --> 00:17:36,080
Speaker 1: the bot, if I'm reading the rules correctly, it's still

306
00:17:36,080 --> 00:17:39,639
Speaker 1: allowed to continue to compete it just maybe at a

307
00:17:39,680 --> 00:17:42,600
Speaker 1: sincere or disadvantage the next round. Sure, let's see. I've

308
00:17:42,760 --> 00:17:45,040
Speaker 1: I've seen a number of different kinds of bots. There

309
00:17:45,040 --> 00:17:47,320
Speaker 1: are kinds, as I said before, that might have a

310
00:17:47,359 --> 00:17:51,280
Speaker 1: saw built into them which attempt to uh to destroy

311
00:17:51,480 --> 00:17:54,879
Speaker 1: pieces of the other body. I've seen um uh bots

312
00:17:54,920 --> 00:17:59,760
Speaker 1: with a hammer or or a hatchet um as. If

313
00:17:59,760 --> 00:18:04,399
Speaker 1: I'm not mistaken, grant of MythBusters. Oh he's built several. Yeah,

314
00:18:04,560 --> 00:18:06,520
Speaker 1: I remember the one that that that I saw of

315
00:18:06,600 --> 00:18:08,919
Speaker 1: his was one of those that had a basically a

316
00:18:08,960 --> 00:18:11,720
Speaker 1: spike that would come down and basically try to impale

317
00:18:12,400 --> 00:18:16,280
Speaker 1: the other robot. They have that the wedges. I remember

318
00:18:16,320 --> 00:18:19,560
Speaker 1: one that didn't have a weapon that would necessarily try

319
00:18:19,600 --> 00:18:22,320
Speaker 1: to destroy the other bot, but would try to capture

320
00:18:22,359 --> 00:18:25,240
Speaker 1: it so it could pick it up and and take

321
00:18:25,280 --> 00:18:28,040
Speaker 1: it into the hazards, drop it off there and let

322
00:18:28,040 --> 00:18:31,399
Speaker 1: the let the board do the rest. Yes, yes, um so,

323
00:18:31,600 --> 00:18:34,800
Speaker 1: and and the box hazards included um saws that were

324
00:18:34,800 --> 00:18:38,399
Speaker 1: mounted underneath the floor, so if your robot happened to

325
00:18:38,400 --> 00:18:41,680
Speaker 1: pass over this basically the hole in the floor where

326
00:18:41,680 --> 00:18:45,320
Speaker 1: the saws come up, the box might send the saws

327
00:18:45,480 --> 00:18:48,119
Speaker 1: up through there and cut your robot. Yeah, it was

328
00:18:48,240 --> 00:18:50,919
Speaker 1: very much like an Indiana Jones movie type thing, like

329
00:18:51,080 --> 00:18:53,640
Speaker 1: spikes could fly up out of the floor or not.

330
00:18:53,680 --> 00:18:55,280
Speaker 1: When I say fly, I don't mean like they would

331
00:18:55,320 --> 00:18:58,359
Speaker 1: actually be projectiles they did stop. Yeah, there was the

332
00:18:58,400 --> 00:19:00,800
Speaker 1: spikes would pop up out of the floor or and

333
00:19:01,320 --> 00:19:06,280
Speaker 1: the spikes wouldn't necessarily impale, but they would often overturn robots. Yes, yes,

334
00:19:06,280 --> 00:19:09,240
Speaker 1: and there was a spike strip on the side now, uh,

335
00:19:09,359 --> 00:19:13,359
Speaker 1: there wasn't any anything necessarily that would you know, it

336
00:19:13,400 --> 00:19:15,760
Speaker 1: didn't pop out of the side of the floor, but

337
00:19:16,040 --> 00:19:18,320
Speaker 1: and it wouldn't necessarily impale your robots. Say you just

338
00:19:18,359 --> 00:19:20,880
Speaker 1: bumped it into there. Well you might think, if you've

339
00:19:20,880 --> 00:19:22,199
Speaker 1: never seen this show, you might think, well, it's a

340
00:19:22,200 --> 00:19:24,240
Speaker 1: big deal, right, Yeah, I can get away from that.

341
00:19:24,600 --> 00:19:27,360
Speaker 1: Well not. If the other robot manages to wedge one

342
00:19:27,359 --> 00:19:30,520
Speaker 1: of the spikes into a tread on your robot or

343
00:19:31,720 --> 00:19:34,639
Speaker 1: hand escape, then you're a sitting duck. Yeah. One of

344
00:19:34,680 --> 00:19:37,160
Speaker 1: the rules of battle Butts is that your robot must

345
00:19:37,160 --> 00:19:40,160
Speaker 1: be able to move at minimum two ft per second

346
00:19:40,280 --> 00:19:42,760
Speaker 1: in a straight line. And if your robot is at

347
00:19:42,840 --> 00:19:45,960
Speaker 1: some point uh disabled enough where it's unable to move,

348
00:19:46,040 --> 00:19:49,200
Speaker 1: like let's say it's just stuck moving in circles, then

349
00:19:49,320 --> 00:19:53,240
Speaker 1: the round maybe ended prematurely, and you know, the victory

350
00:19:53,280 --> 00:19:56,960
Speaker 1: given to the other robot because you know you at

351
00:19:57,000 --> 00:19:59,480
Speaker 1: that point, really there's no way for you to to

352
00:20:00,040 --> 00:20:03,040
Speaker 1: when unless the other robot suffers a failure, and in

353
00:20:03,080 --> 00:20:05,879
Speaker 1: which case that's not kind of a hollow victory. Um.

354
00:20:06,760 --> 00:20:10,880
Speaker 1: There there are certain things that are specifically not allowed. Yes,

355
00:20:11,720 --> 00:20:16,600
Speaker 1: projectiles are not allowed unless they are tethered to the robot.

356
00:20:17,760 --> 00:20:20,560
Speaker 1: I would assume this is probably a safety precaution because

357
00:20:20,640 --> 00:20:25,400
Speaker 1: while the the battle box is enclosed, enclosed, and it's

358
00:20:25,480 --> 00:20:28,359
Speaker 1: likely to protect you from a piece of flying shrapnel

359
00:20:28,400 --> 00:20:31,000
Speaker 1: that might spin off of a robot during a collision,

360
00:20:31,760 --> 00:20:35,800
Speaker 1: if you had a machine gun mounted on your battle bot,

361
00:20:36,040 --> 00:20:39,600
Speaker 1: it probably would be you know, it could be depending

362
00:20:39,600 --> 00:20:42,280
Speaker 1: on where you're using, strong enough to pierce the box

363
00:20:42,359 --> 00:20:45,240
Speaker 1: and injure the the spectators outside. This is why I'm

364
00:20:45,280 --> 00:20:49,120
Speaker 1: never allowed to compete. There's no fun in that. Yeah.

365
00:20:49,160 --> 00:20:52,040
Speaker 1: So you can have a projectile if it is tethered

366
00:20:52,080 --> 00:20:54,399
Speaker 1: to the robot, and the project the tether has to

367
00:20:54,400 --> 00:20:58,119
Speaker 1: be eight feet or or less in length. Um, you

368
00:20:58,200 --> 00:21:01,679
Speaker 1: cannot have anything that goes beyond that. You you are

369
00:21:01,720 --> 00:21:04,760
Speaker 1: allowed to use covering weapons, So weapons that could cover

370
00:21:05,080 --> 00:21:08,840
Speaker 1: a uh AN opponent, but they must have the covering

371
00:21:08,920 --> 00:21:11,840
Speaker 1: must be either rigid or semi rigid, and the the

372
00:21:11,880 --> 00:21:14,960
Speaker 1: attacking robot must be able to remove the cover at

373
00:21:14,960 --> 00:21:17,159
Speaker 1: any time. So, in other words, you can have like

374
00:21:17,240 --> 00:21:19,840
Speaker 1: a solid not a net, but like to say, like

375
00:21:19,840 --> 00:21:22,760
Speaker 1: a little cage on a lever come down and and

376
00:21:22,960 --> 00:21:25,960
Speaker 1: encapsulate an opponent, and then you drive your opponent into

377
00:21:26,000 --> 00:21:28,439
Speaker 1: a pit. You could do that, but you could not

378
00:21:28,920 --> 00:21:32,120
Speaker 1: shoot a net at a at a robot and then

379
00:21:32,200 --> 00:21:34,760
Speaker 1: foul its wheels that way. In fact, you're not allowed

380
00:21:34,760 --> 00:21:37,800
Speaker 1: to use any weapons that were specifically designed to foul

381
00:21:38,359 --> 00:21:43,040
Speaker 1: a a a robot's wheels or treads just by getting

382
00:21:43,080 --> 00:21:45,879
Speaker 1: tangled in there. So you couldn't drop like string or

383
00:21:45,960 --> 00:21:48,760
Speaker 1: rope or um. They talk about. You can use balloons

384
00:21:48,800 --> 00:21:54,080
Speaker 1: and air bags to push a robot, but you can't

385
00:21:54,200 --> 00:21:56,520
Speaker 1: use them in such a way so that they come

386
00:21:56,560 --> 00:21:59,919
Speaker 1: off your robot, deflate and then become a fouling hazard.

387
00:22:02,000 --> 00:22:05,239
Speaker 1: Not intentionally anyway. Yeah, if it happens by accident, you

388
00:22:05,520 --> 00:22:08,680
Speaker 1: you you know, that's that's another matter. Electro Magnets are

389
00:22:08,800 --> 00:22:10,960
Speaker 1: there's a there's a very specific use, so you can

390
00:22:11,000 --> 00:22:14,040
Speaker 1: you can have them mounted on your robot and use

391
00:22:14,119 --> 00:22:15,960
Speaker 1: them that way, but they are not supposed to be

392
00:22:15,960 --> 00:22:18,960
Speaker 1: designed to interfere with the radio frequency signal that's sent

393
00:22:19,000 --> 00:22:22,400
Speaker 1: by the remote control and uh, you can't have like

394
00:22:22,440 --> 00:22:26,480
Speaker 1: a cattle prode or uh, something that's going to essentially

395
00:22:26,680 --> 00:22:29,760
Speaker 1: create an electromagnetic field that's going to be so powerful

396
00:22:29,760 --> 00:22:33,480
Speaker 1: that it just causes a robot to you know, go

397
00:22:33,680 --> 00:22:35,600
Speaker 1: down you can't do anything like that. Like, you know,

398
00:22:36,400 --> 00:22:39,000
Speaker 1: that also destroys my plan for my e MP robot

399
00:22:39,000 --> 00:22:41,399
Speaker 1: that was building. I can't do that anymore. And I

400
00:22:41,480 --> 00:22:44,239
Speaker 1: was just about to figure out how I could do

401
00:22:44,280 --> 00:22:47,679
Speaker 1: it without detonating a nuclear warhead. So I was so close.

402
00:22:48,040 --> 00:22:52,639
Speaker 1: But um, you can't use flame or uh weapons that

403
00:22:52,680 --> 00:22:56,880
Speaker 1: would obscure vision as um as a tactic. You can

404
00:22:57,040 --> 00:23:00,560
Speaker 1: use the both of those things in what they call effects.

405
00:23:01,080 --> 00:23:03,440
Speaker 1: But that's sort of like you guys, if you've ever

406
00:23:03,440 --> 00:23:07,119
Speaker 1: watched professional wrestling and they announced the wrestler, and the

407
00:23:07,160 --> 00:23:09,639
Speaker 1: wrestler comes down the ramp and they're all these pyro

408
00:23:09,760 --> 00:23:12,320
Speaker 1: effects that go off and there's a big video playing

409
00:23:12,320 --> 00:23:14,680
Speaker 1: in the background and maybe smoke is coming up. Um,

410
00:23:14,720 --> 00:23:17,200
Speaker 1: you know that's all for the effect of him taking

411
00:23:17,240 --> 00:23:19,920
Speaker 1: the stage or her taking the stage before the match.

412
00:23:20,119 --> 00:23:22,000
Speaker 1: Same sort of thing. That's the idea is that, you know,

413
00:23:22,000 --> 00:23:23,919
Speaker 1: like you have a little flame shooting out the back. Well,

414
00:23:23,960 --> 00:23:27,080
Speaker 1: that's okay if it's just for the entrance or you know,

415
00:23:27,200 --> 00:23:30,159
Speaker 1: a victory lap or something, but you can't use it

416
00:23:30,200 --> 00:23:32,560
Speaker 1: as a weapon. Yeah, but there are things, there are

417
00:23:32,560 --> 00:23:36,080
Speaker 1: reasons why you might not want to do that, including

418
00:23:36,119 --> 00:23:38,720
Speaker 1: the fact that you might have a flammable material on board.

419
00:23:38,760 --> 00:23:42,280
Speaker 1: Now you can't have an internal combustion engine powering your

420
00:23:42,400 --> 00:23:48,680
Speaker 1: bought a motor. But the thing again is if, for example,

421
00:23:48,720 --> 00:23:52,480
Speaker 1: the other bought severs your gas line or whatever it

422
00:23:52,520 --> 00:23:56,000
Speaker 1: is that you're using for fuel, uh, and uh some

423
00:23:56,080 --> 00:24:00,000
Speaker 1: spark catches it on fire, you may lose your entire bot. Uh,

424
00:24:00,280 --> 00:24:02,360
Speaker 1: both bots might get lost in that, because, yeah, you're

425
00:24:02,359 --> 00:24:05,240
Speaker 1: talking about a true flame hazard there. It's a I mean,

426
00:24:05,600 --> 00:24:08,679
Speaker 1: by definition, it has to be a combustible liquid. I

427
00:24:08,720 --> 00:24:10,720
Speaker 1: assume that they would stop the fight and someone would

428
00:24:10,720 --> 00:24:12,360
Speaker 1: go in with a fire extinguisher to put it out,

429
00:24:12,359 --> 00:24:17,760
Speaker 1: but not I would assume before it would do some damage. Um. Also,

430
00:24:17,880 --> 00:24:19,320
Speaker 1: it's going to add to the weight. If you had

431
00:24:19,400 --> 00:24:22,800
Speaker 1: a smoke machine and a you know, little flamethrower on

432
00:24:22,840 --> 00:24:26,280
Speaker 1: there for the effects, then that's how many idly a

433
00:24:26,320 --> 00:24:30,960
Speaker 1: couple of pounds um. And you know, some bots are

434
00:24:31,000 --> 00:24:32,880
Speaker 1: going to want to stay light and some are going

435
00:24:32,920 --> 00:24:34,879
Speaker 1: to want to be heavier, depending on the kind of

436
00:24:34,880 --> 00:24:37,800
Speaker 1: attack that that you're delivering. So you really have to

437
00:24:37,800 --> 00:24:41,800
Speaker 1: be very strategic about what you add to your bot. UM.

438
00:24:41,960 --> 00:24:45,760
Speaker 1: Some bots themselves are weapons to UM. Some of my

439
00:24:45,800 --> 00:24:49,240
Speaker 1: favorites are are what they call spin bots UM. A

440
00:24:49,280 --> 00:24:53,000
Speaker 1: couple of them were made from an upside down walk um,

441
00:24:53,040 --> 00:24:56,600
Speaker 1: which doesn't sound very you know, scary, but if you

442
00:24:56,640 --> 00:24:59,640
Speaker 1: mount things on the outside of these bots and you're

443
00:24:59,680 --> 00:25:02,880
Speaker 1: going at a certain number of RPMs, when you come

444
00:25:02,880 --> 00:25:06,480
Speaker 1: into the say really thin titanium coating of another bot,

445
00:25:06,520 --> 00:25:09,040
Speaker 1: it may rip the outside of that thing right off. Yeah. Yeah,

446
00:25:09,080 --> 00:25:11,720
Speaker 1: these these things like I've seen somewhere. It was essentially

447
00:25:11,720 --> 00:25:14,879
Speaker 1: like a lawnmower arm that would spin around on the

448
00:25:14,920 --> 00:25:17,000
Speaker 1: top of it. And yeah, usually you have a shell

449
00:25:17,160 --> 00:25:19,280
Speaker 1: on the outside of the robot that is capable of

450
00:25:19,359 --> 00:25:23,120
Speaker 1: spinning in one direction or the other. Uh, and then

451
00:25:23,359 --> 00:25:26,920
Speaker 1: the wheels and everything are independent of that, so they

452
00:25:26,960 --> 00:25:29,919
Speaker 1: you know, the spinning motion isn't what propels the robot

453
00:25:29,960 --> 00:25:34,439
Speaker 1: across the floor. It's just another element to the robot. Um.

454
00:25:34,560 --> 00:25:37,600
Speaker 1: It's a very interesting type of weapon. Yeah, it's tricky too,

455
00:25:37,640 --> 00:25:39,560
Speaker 1: because I mean it's going to throw off. The way

456
00:25:39,560 --> 00:25:42,920
Speaker 1: the robot handles is just just from the force that's

457
00:25:42,960 --> 00:25:47,720
Speaker 1: generated from the spinning attack. The impact usually causes both

458
00:25:47,840 --> 00:25:50,600
Speaker 1: robots to go off in a different direction. It looks

459
00:25:50,600 --> 00:25:53,560
Speaker 1: like when a pinball hits a like a bumper and

460
00:25:53,640 --> 00:25:55,679
Speaker 1: a pinball machine. It's just like bing and then it

461
00:25:55,760 --> 00:26:00,119
Speaker 1: just flies across the floor. Um, the I shall will

462
00:26:00,119 --> 00:26:01,600
Speaker 1: point out this point when I when I mentioned that

463
00:26:01,640 --> 00:26:06,359
Speaker 1: they're independent. Uh, each team is allowed to operators. You

464
00:26:06,359 --> 00:26:08,800
Speaker 1: can have two people operating the robots. So you could

465
00:26:08,840 --> 00:26:13,040
Speaker 1: have one person who's essentially steering the robot and driver driver,

466
00:26:13,119 --> 00:26:16,120
Speaker 1: and another person would be the the one operating the weapons.

467
00:26:16,400 --> 00:26:18,679
Speaker 1: And usually you would have two separate controllers working on

468
00:26:18,720 --> 00:26:22,840
Speaker 1: two separate frequencies. Uh. That brings me to another weapon

469
00:26:22,880 --> 00:26:24,840
Speaker 1: that you can't use. You can't use any kind of

470
00:26:24,840 --> 00:26:28,399
Speaker 1: weapon that would interfere with your opponents radio frequencies. So

471
00:26:28,440 --> 00:26:31,040
Speaker 1: no fair jamming the other guy. Yeah, which is yet

472
00:26:31,080 --> 00:26:33,680
Speaker 1: again all the things that I would plan. Like, here's

473
00:26:33,720 --> 00:26:36,480
Speaker 1: the brilliance of my plan is you immediately disabled the

474
00:26:36,520 --> 00:26:38,440
Speaker 1: other robot before it even has a chance to do anything,

475
00:26:38,480 --> 00:26:39,840
Speaker 1: and then you just go on wump up on it.

476
00:26:39,840 --> 00:26:41,360
Speaker 1: Actually you wouldn't even have to do that. You could

477
00:26:41,359 --> 00:26:43,879
Speaker 1: just move in a straight line. The other robot can't move,

478
00:26:44,440 --> 00:26:46,679
Speaker 1: it's just you know, it's disqualified. It has to be

479
00:26:46,720 --> 00:26:48,520
Speaker 1: able to show that it can still move in order

480
00:26:48,560 --> 00:26:52,400
Speaker 1: to be considered viable. Um. Well, even if you don't

481
00:26:52,400 --> 00:26:55,280
Speaker 1: consider that playing dirty, you have to take into account

482
00:26:55,320 --> 00:26:57,160
Speaker 1: the effect it has in the spectators. When the other

483
00:26:57,560 --> 00:27:00,920
Speaker 1: robot doesn't even move, it's no fun, and when both

484
00:27:01,000 --> 00:27:03,520
Speaker 1: robots don't get into it a little bit fun. I'm

485
00:27:03,560 --> 00:27:06,960
Speaker 1: looking at winning dude. Yeah, okay, so um, but here's

486
00:27:06,960 --> 00:27:08,879
Speaker 1: some other stuff that you can do that or that

487
00:27:09,000 --> 00:27:12,160
Speaker 1: that's kind of cool. You can have a jumping robot. Okay,

488
00:27:12,280 --> 00:27:16,560
Speaker 1: you are, Um, you're jumping robot can only there's a

489
00:27:16,600 --> 00:27:19,200
Speaker 1: limit on how high robots are allowed to jump within

490
00:27:19,280 --> 00:27:22,160
Speaker 1: battle bots. That limit is six feet. I was telling

491
00:27:22,200 --> 00:27:25,119
Speaker 1: Chris earlier, if I saw a robot jump six ft

492
00:27:25,160 --> 00:27:28,040
Speaker 1: in the air straight up, I would immediately turn around

493
00:27:28,040 --> 00:27:29,879
Speaker 1: and walk out of the building for fear of my

494
00:27:30,040 --> 00:27:33,160
Speaker 1: life because I don't know. There's something about jumping robot

495
00:27:33,240 --> 00:27:36,840
Speaker 1: that just scares me. Um, there is. Uh. You can

496
00:27:36,880 --> 00:27:39,040
Speaker 1: have a hovercraft as a robot. You could you could

497
00:27:39,040 --> 00:27:42,760
Speaker 1: build your robot could propel itself via the same method

498
00:27:42,800 --> 00:27:45,800
Speaker 1: as a hovercraft. You are not allowed to have powered

499
00:27:45,800 --> 00:27:49,480
Speaker 1: flight or jets or rockets. Though yet again I knew

500
00:27:49,480 --> 00:27:53,119
Speaker 1: you were going to say that, so um also also

501
00:27:53,600 --> 00:27:57,080
Speaker 1: lighten sound. Um, you can't have any device on your

502
00:27:57,200 --> 00:28:02,120
Speaker 1: robot that is meant to blind your opponent, your human opponent. Yeah,

503
00:28:02,160 --> 00:28:04,840
Speaker 1: you can't have like a like a fog light attached

504
00:28:04,880 --> 00:28:07,240
Speaker 1: to your robot that you turn on whenever it's facing

505
00:28:07,280 --> 00:28:10,639
Speaker 1: your opponents. Um And, you can't. You can't use lasers

506
00:28:10,720 --> 00:28:12,679
Speaker 1: either on the outside. You can use lasers on the

507
00:28:12,680 --> 00:28:16,600
Speaker 1: inside if they're used to operate your robot in any way,

508
00:28:16,680 --> 00:28:19,119
Speaker 1: that's fine. You just can't have any exposed lasers that

509
00:28:19,160 --> 00:28:21,400
Speaker 1: are meant to be in effect or anything like that.

510
00:28:22,160 --> 00:28:24,119
Speaker 1: Um And, as we said, you can use flames and

511
00:28:24,160 --> 00:28:27,640
Speaker 1: smoke for just effect purposes. If you are using flames,

512
00:28:28,040 --> 00:28:31,080
Speaker 1: you can only use propane or butane as the fuel,

513
00:28:31,680 --> 00:28:33,840
Speaker 1: and it has to be in gas form. It cannot

514
00:28:33,840 --> 00:28:36,320
Speaker 1: shoot it as liquid or gel, because obviously that would

515
00:28:36,320 --> 00:28:40,360
Speaker 1: be much more dangerous. Um And I was mentioning the

516
00:28:40,680 --> 00:28:45,160
Speaker 1: autonomous robots. You are allowed to build an autonomous robot. Now,

517
00:28:45,160 --> 00:28:48,440
Speaker 1: an autonomous robot acts on its own right. It has

518
00:28:48,480 --> 00:28:53,480
Speaker 1: its own ability to perform actions and and on a

519
00:28:53,480 --> 00:28:57,640
Speaker 1: certain level, make decisions and act upon them. But the

520
00:28:57,720 --> 00:29:01,760
Speaker 1: rule for autonomous robots is that when the match starts,

521
00:29:01,800 --> 00:29:04,000
Speaker 1: it has to be under human control. You have to

522
00:29:04,000 --> 00:29:06,560
Speaker 1: be able to switch it to autonomous modes. So essentially

523
00:29:06,640 --> 00:29:09,560
Speaker 1: it's like you know autopilot, right, you push a button

524
00:29:09,680 --> 00:29:12,920
Speaker 1: or whatever and it switches to autonomous UH mode, and

525
00:29:12,960 --> 00:29:15,040
Speaker 1: then you have to be able to have the ability

526
00:29:15,400 --> 00:29:19,320
Speaker 1: to butt in and take it over manually if needed.

527
00:29:19,960 --> 00:29:22,920
Speaker 1: So as long as it follows those rules, you're allowed

528
00:29:22,960 --> 00:29:28,160
Speaker 1: to have an autonomous robot. That's actually pretty cool. I

529
00:29:28,160 --> 00:29:30,320
Speaker 1: don't remember them doing that back when I was watching

530
00:29:30,320 --> 00:29:32,280
Speaker 1: the show, and unfortunately I haven't seen any of the

531
00:29:32,320 --> 00:29:35,840
Speaker 1: competition since then. UM, if you happen to be in Miami,

532
00:29:35,840 --> 00:29:41,400
Speaker 1: Florida on February, that doesn't give you much time. Based

533
00:29:41,400 --> 00:29:44,080
Speaker 1: on when this podcast is going to publish, you can

534
00:29:44,160 --> 00:29:47,400
Speaker 1: you can see this year's competition at the Coconut Grove

535
00:29:47,440 --> 00:29:52,000
Speaker 1: Expo Center. UM. So getting back to the the actual format.

536
00:29:52,120 --> 00:29:54,080
Speaker 1: So you have you've decided to build a robot. You've

537
00:29:54,120 --> 00:29:56,200
Speaker 1: made all the tough choices. What kind of weapon you want?

538
00:29:56,320 --> 00:29:58,280
Speaker 1: What do you want to build it out of? You've

539
00:29:58,280 --> 00:30:02,360
Speaker 1: had your metallurgically UH gifted friends help you with the

540
00:30:02,440 --> 00:30:06,560
Speaker 1: choice between titanium and steel. Um do you really want

541
00:30:06,560 --> 00:30:09,960
Speaker 1: to use lex hand for the outside? I don't know. Um,

542
00:30:10,200 --> 00:30:12,680
Speaker 1: you've built your bot, you've got extra parts, you've got

543
00:30:12,760 --> 00:30:14,560
Speaker 1: extra tools, you've got your buddies to help you with it.

544
00:30:15,160 --> 00:30:18,520
Speaker 1: You show up at the tournament and you when you enter,

545
00:30:18,600 --> 00:30:20,880
Speaker 1: you're in a tournament grid. So you go up for

546
00:30:20,960 --> 00:30:26,080
Speaker 1: your first bout, and basically it's if you win, you continue, uh,

547
00:30:26,120 --> 00:30:28,400
Speaker 1: you lose, and you stick around and help people out

548
00:30:28,520 --> 00:30:31,640
Speaker 1: because the only people who can share parts, according to

549
00:30:31,680 --> 00:30:34,000
Speaker 1: the rules are people who are already out of the competition.

550
00:30:34,040 --> 00:30:37,760
Speaker 1: So say you've won, but your motor burned out that

551
00:30:37,840 --> 00:30:41,480
Speaker 1: you need for your your actuator arm for your weapon, Well,

552
00:30:41,600 --> 00:30:44,160
Speaker 1: somebody from a previous round or from another competition can

553
00:30:44,240 --> 00:30:47,120
Speaker 1: loan you a motor to use in your bot if

554
00:30:47,120 --> 00:30:49,400
Speaker 1: you don't have one handy, but that person has to

555
00:30:49,440 --> 00:30:52,440
Speaker 1: have already had their robot eliminated. Um. That's why it's

556
00:30:52,440 --> 00:30:54,760
Speaker 1: always good to carry extras of these parts because you're

557
00:30:54,760 --> 00:30:58,800
Speaker 1: gonna need them. Um. But basically, as you progress up

558
00:30:58,840 --> 00:31:01,840
Speaker 1: the ladder, uh, you know eventually they crown a winner.

559
00:31:01,880 --> 00:31:03,840
Speaker 1: Now that this is done in several classes, just like

560
00:31:03,880 --> 00:31:09,240
Speaker 1: you would see in human boxing matches, they're weight classes, right,

561
00:31:09,280 --> 00:31:12,080
Speaker 1: And now that there are in the competitions more robust

562
00:31:12,160 --> 00:31:15,520
Speaker 1: you have high school, college, and pro levels and weight

563
00:31:15,560 --> 00:31:17,960
Speaker 1: classes within those levels, so you don't have a really

564
00:31:18,000 --> 00:31:20,920
Speaker 1: tiny spin bot going up against a you know, a

565
00:31:21,040 --> 00:31:24,560
Speaker 1: crusher buzz saw from you know, the top weight class.

566
00:31:24,680 --> 00:31:27,080
Speaker 1: I have them matched evenly, and and they give out

567
00:31:27,080 --> 00:31:31,520
Speaker 1: awards based on that, um, you know, prize money. There's

568
00:31:31,640 --> 00:31:34,120
Speaker 1: usually something I think that they try to give people.

569
00:31:34,720 --> 00:31:37,840
Speaker 1: I don't know that anyone has become rich being a

570
00:31:37,880 --> 00:31:42,000
Speaker 1: battle bot owner. Yeah, it's really an engineering contest more

571
00:31:42,000 --> 00:31:43,960
Speaker 1: than anything else. Yeah, I think it's I think it's

572
00:31:44,120 --> 00:31:47,760
Speaker 1: more for fun than anything else and bragging rights, um,

573
00:31:47,880 --> 00:31:50,640
Speaker 1: unless you're on the show's space, in which case it's

574
00:31:50,680 --> 00:31:54,360
Speaker 1: a matter of honor. Yes, But um, I think more

575
00:31:54,400 --> 00:31:57,080
Speaker 1: than that though, from what the research I've done since I,

576
00:31:57,240 --> 00:31:59,600
Speaker 1: as I said, I hadn't watched the show in many years,

577
00:31:59,640 --> 00:32:01,640
Speaker 1: I was sort about of it, it seems like there's

578
00:32:01,680 --> 00:32:05,160
Speaker 1: been a real community spring up to teach people how

579
00:32:05,200 --> 00:32:09,400
Speaker 1: to build robots, you know, for hobbyists. Um, there are

580
00:32:09,400 --> 00:32:12,560
Speaker 1: people who make parts for competitions. Now that that weren't

581
00:32:12,600 --> 00:32:15,360
Speaker 1: I mean people take used to take uh you know,

582
00:32:15,480 --> 00:32:18,760
Speaker 1: chainsaws and other parts off the shelf for machine things themselves.

583
00:32:19,080 --> 00:32:24,760
Speaker 1: There these you don't have to be a complete uh

584
00:32:25,040 --> 00:32:27,720
Speaker 1: robotics expert to do this kind of thing. You can

585
00:32:27,760 --> 00:32:30,200
Speaker 1: really get into it and ease yourself in more than

586
00:32:30,240 --> 00:32:31,560
Speaker 1: you used to be able to. And I think there's

587
00:32:31,560 --> 00:32:35,000
Speaker 1: a real um community of people where they just hang

588
00:32:35,000 --> 00:32:38,720
Speaker 1: out and share ideas now where there there probably wasn't before.

589
00:32:38,760 --> 00:32:42,280
Speaker 1: So over the span of uh, just a few years,

590
00:32:42,800 --> 00:32:44,920
Speaker 1: you know, this is the kind of activity that sprung up.

591
00:32:44,960 --> 00:32:48,560
Speaker 1: And I think competitions like this and and first the

592
00:32:48,600 --> 00:32:52,080
Speaker 1: first robotics competition, you know, it's it encourages people to

593
00:32:52,200 --> 00:32:54,400
Speaker 1: learn more about it, and younger people are getting involved

594
00:32:54,400 --> 00:32:58,480
Speaker 1: in it too, so uh, congratulations to them. I hope

595
00:32:58,480 --> 00:33:00,640
Speaker 1: it will make a return to TV. I really miss

596
00:33:00,720 --> 00:33:03,280
Speaker 1: watching the show. It was so much fun. It's a

597
00:33:03,320 --> 00:33:05,680
Speaker 1: lot of fun. And again, you know, nobody people are

598
00:33:05,680 --> 00:33:07,479
Speaker 1: out a lot of money when they lose, but watching

599
00:33:07,520 --> 00:33:10,880
Speaker 1: the robots take each other apart, which is so much fun.

600
00:33:11,200 --> 00:33:15,160
Speaker 1: And it's great to teach the basics of engineering robotics

601
00:33:15,160 --> 00:33:17,560
Speaker 1: that kind of thing. And you often will see things

602
00:33:17,640 --> 00:33:20,680
Speaker 1: that show that people are thinking outside the box, so

603
00:33:20,720 --> 00:33:25,480
Speaker 1: to speak, and that uh that possibly have have applications

604
00:33:25,480 --> 00:33:28,360
Speaker 1: beyond what you know, what some might see is just

605
00:33:28,440 --> 00:33:32,680
Speaker 1: kind of a hobby, so it's simar about Yeah, definitely.

606
00:33:33,200 --> 00:33:35,800
Speaker 1: So if any of you guys have any comments about

607
00:33:35,840 --> 00:33:38,040
Speaker 1: battle bots, maybe you built one and you would like

608
00:33:38,080 --> 00:33:40,360
Speaker 1: to tell us about it, I'd love to hear that, definitely,

609
00:33:40,480 --> 00:33:42,800
Speaker 1: let us know you can. You can contact us on
