00:00:02,040 --> 00:00:07,080
Speaker 1: Welcome to brain Stuff from how Stuff Works. Hey, brain Stuff,

2
00:00:07,080 --> 00:00:09,960
Speaker 1: I'm Lauren voc Obam, And if science fiction has taught

3
00:00:10,039 --> 00:00:13,920
Speaker 1: us anything, it's that giant piloted robotic humanoids will eventually

4
00:00:13,960 --> 00:00:16,680
Speaker 1: be essential to the protection of everything we hold Dear

5
00:00:17,600 --> 00:00:20,800
Speaker 1: invading Kaiju from another dimension. Send in the yagers Row

6
00:00:20,880 --> 00:00:24,960
Speaker 1: beasts from Planet Doom, better assemble Vultron, And, as James

7
00:00:25,000 --> 00:00:28,320
Speaker 1: Cameron's Aliens taught us in six even a non combat

8
00:00:28,400 --> 00:00:30,600
Speaker 1: nex suit can make all the difference against an extra

9
00:00:30,680 --> 00:00:35,239
Speaker 1: terrestrial threat. Another influential example is our X seventy eight

10
00:00:35,320 --> 00:00:39,040
Speaker 1: Dash to Gundam. The titular piloted giant robot entered the

11
00:00:39,040 --> 00:00:41,920
Speaker 1: world in nineteen seventy nine as part of Yoshiyuki Tomino's

12
00:00:42,000 --> 00:00:46,200
Speaker 1: mobile suit Gundam franchise, which remains popular today. But could

13
00:00:46,240 --> 00:00:50,160
Speaker 1: we build our own gun Dams? The simple answer is yes.

14
00:00:50,640 --> 00:00:53,320
Speaker 1: In fact, scientists have been tackling various aspects of the

15
00:00:53,320 --> 00:00:56,880
Speaker 1: technology since at least the late nineteenth and early twentieth centuries.

16
00:00:57,320 --> 00:01:00,360
Speaker 1: During that time, both Russian and American inventors it explored

17
00:01:00,400 --> 00:01:04,160
Speaker 1: the possibility of mechanically enhanced exo skeletons to aid humans

18
00:01:04,160 --> 00:01:07,560
Speaker 1: in various physical movements. Since that time, we've continued to

19
00:01:07,560 --> 00:01:11,760
Speaker 1: see exo skeleton advancements aimed at injury rehabilitation, space travel,

20
00:01:11,920 --> 00:01:17,360
Speaker 1: industrial labor, and yes, even military combat and okay, power

21
00:01:17,480 --> 00:01:19,680
Speaker 1: armor is nice and all, but it's hardly a giant

22
00:01:19,760 --> 00:01:22,440
Speaker 1: robot that stomps around and punches monsters in the face.

23
00:01:23,240 --> 00:01:27,360
Speaker 1: What about true towering Mecca's Well, the answer here is

24
00:01:27,520 --> 00:01:30,559
Speaker 1: also a yes. Within the field of robotics, we've seen

25
00:01:30,560 --> 00:01:34,080
Speaker 1: tremendous achievements in the creation of remote control, autonomous, and

26
00:01:34,160 --> 00:01:38,240
Speaker 1: semi autonomous machines. Today, military drones haunt the skies of

27
00:01:38,280 --> 00:01:41,760
Speaker 1: our various global combat zones, and space exploration probes have

28
00:01:41,840 --> 00:01:44,880
Speaker 1: delivered wheeled rovers to other worlds. We've even given our

29
00:01:44,880 --> 00:01:48,240
Speaker 1: wheeled robots arms for tasks from bomb dispersal to Martian

30
00:01:48,280 --> 00:01:52,480
Speaker 1: soil sampling and deep sea exploration. But none of these

31
00:01:52,520 --> 00:01:57,360
Speaker 1: mechanical minions boasts legs. Even the humanoid roboknot developed by

32
00:01:57,480 --> 00:02:01,360
Speaker 1: NASA's Lyndon B. Johnson's Space Center didn't acquire climbing legs

33
00:02:01,480 --> 00:02:05,040
Speaker 1: until its second iteration. For proper Gundams to one day

34
00:02:05,040 --> 00:02:08,400
Speaker 1: walk the planet will need proper robot legs, and this

35
00:02:08,520 --> 00:02:11,440
Speaker 1: too has featured into the work of various robotics programs.

36
00:02:12,200 --> 00:02:15,320
Speaker 1: The most famous of these is Boston Dynamics, military funded

37
00:02:15,400 --> 00:02:18,920
Speaker 1: walker programs such as Big Dog and Cheetah, and not

38
00:02:19,040 --> 00:02:21,160
Speaker 1: just because they inspired the killer robots in the Black

39
00:02:21,200 --> 00:02:25,880
Speaker 1: Mirror episode Metal Head. Because while aerial and nautical robots

40
00:02:25,880 --> 00:02:28,240
Speaker 1: can get by just fine without a leg to stand on,

41
00:02:28,520 --> 00:02:31,960
Speaker 1: terrestrial robots are a different matter. Wheels are great on

42
00:02:32,000 --> 00:02:35,320
Speaker 1: the road and unobstructed landscapes, but legs provide the most

43
00:02:35,400 --> 00:02:40,040
Speaker 1: versatility for diverse environments. True wheel like structures only rarely

44
00:02:40,040 --> 00:02:43,880
Speaker 1: occur in biology, such as the bacterial flagellum, a structure

45
00:02:43,880 --> 00:02:47,440
Speaker 1: found in such species as the Bacterium equali. Legs, on

46
00:02:47,480 --> 00:02:52,040
Speaker 1: the other hand, are natural selections primary solution to terrestrial transportation,

47
00:02:52,560 --> 00:02:55,000
Speaker 1: so it makes sense to copy evolution in this regard,

48
00:02:55,320 --> 00:02:58,280
Speaker 1: and biommetic engineers have looked to all manner of leg

49
00:02:58,360 --> 00:03:03,799
Speaker 1: rangements for inspiration, from humans to millipedes. But here's the catch.

50
00:03:04,240 --> 00:03:08,400
Speaker 1: Led movement requires a great deal of programming, complexity and power.

51
00:03:08,800 --> 00:03:11,119
Speaker 1: It may feel easy for most of us, but our

52
00:03:11,200 --> 00:03:14,320
Speaker 1: minds and bodies are highly evolved for the task. Even

53
00:03:14,320 --> 00:03:17,639
Speaker 1: a fully piloted gundam, say one word's movements are mapped

54
00:03:17,680 --> 00:03:20,680
Speaker 1: on those of the pilot. Would require a tremendous amount

55
00:03:20,720 --> 00:03:24,680
Speaker 1: of biometic engineering, and semi autonomous units would require the

56
00:03:24,720 --> 00:03:28,880
Speaker 1: dexterity and spatial awareness to avoid the pitfalls of for example,

57
00:03:29,080 --> 00:03:32,040
Speaker 1: the e D two oh nine in RoboCup, which stomped

58
00:03:32,040 --> 00:03:35,080
Speaker 1: around on two feet but was incapable of navigating stairs.

59
00:03:36,200 --> 00:03:40,000
Speaker 1: But the Mecca dream is strong. While various robotics companies

60
00:03:40,040 --> 00:03:43,680
Speaker 1: continue to develop the necessary technology, sci fi fans also

61
00:03:43,760 --> 00:03:46,680
Speaker 1: go at it alone. Functional MECA suites have strolled the

62
00:03:46,720 --> 00:03:50,320
Speaker 1: Plaia at Burning Man and paraded at various conventions, and

63
00:03:50,480 --> 00:03:54,280
Speaker 1: Japanese engineer Masaki Nagumo built a working life size model

64
00:03:54,320 --> 00:03:58,400
Speaker 1: of a Gundam in the Mecca, dubbed l W Mononofu

65
00:03:58,680 --> 00:04:01,280
Speaker 1: stands twenty eight feet hall that's about eight point five

66
00:04:01,320 --> 00:04:04,840
Speaker 1: meters and ways seven point seven tons or about seven

67
00:04:04,840 --> 00:04:07,840
Speaker 1: metric tons. It's too big to leave the factory space

68
00:04:07,880 --> 00:04:10,240
Speaker 1: that it calls home, but Nagobo rents it and other

69
00:04:10,280 --> 00:04:12,680
Speaker 1: mecca's out for a little under a thousand bucks an hour.

70
00:04:13,160 --> 00:04:15,440
Speaker 1: It's not protecting the world from alien attacks, but it's

71
00:04:15,480 --> 00:04:19,120
Speaker 1: quite a hit for kid's birthday parties. Though one note

72
00:04:19,160 --> 00:04:23,159
Speaker 1: here if aliens or giant monsters do attack well, Mecca's

73
00:04:23,279 --> 00:04:26,240
Speaker 1: might not be the best option anyway. As was pointed

74
00:04:26,240 --> 00:04:28,880
Speaker 1: out in the magazine Popular Mechanics, the yagers from the

75
00:04:28,920 --> 00:04:33,040
Speaker 1: Pacific Rim films are entirely outclassed by existing aerial bombers

76
00:04:33,080 --> 00:04:41,440
Speaker 1: and attack helicopters. Today's episode was written by Robert Lamb

77
00:04:41,440 --> 00:04:44,320
Speaker 1: and produced by Tyler Clang. It was also suggested to

78
00:04:44,400 --> 00:04:47,960
Speaker 1: us by Lucas, twelve years of age from Ontario, Canada. Lucas,

79
00:04:48,040 --> 00:04:52,120
Speaker 1: we hope that answer was satisfactory, nay, exemplary listeners. If
