We all know that ants and other insects at this size scale

We need mechanisms like legs and efficient motors

00:50
in order to support that locomotion,
13
50223

00:52
and we need the sensors, power and control

It shows a cockroach moving over incredibly rough terrain

01:15
without tipping over,
22
75342
1853
01:17
and it's able to do this because its legs are a combination of rigid materials,

3997
이게 κ°€λŠ₯ν•œ 것이 닀리가 νŠΌνŠΌν•œ 물질둜 λ˜μ–΄ μžˆλŠ”λ°

which is what we traditionally use to make robots,

01:23
and soft materials.
25
83545
1599
01:26
Jumping is another really interesting way to get around when you're very small.
26

01:30
So these insects store energy in a spring and release that really quickly

01:38
So one of the big contributions from my lab

제 μ—°κ΅¬μ‹€μ—μ„œ 얻은 큰 성과쀑 ν•˜λ‚˜κ°€

01:46
So this jumping mechanism is about four millimeters on a side,

01:51
The hard material here is silicon, and the soft material is silicone rubber.
34
111220
3838
01:55
And the basic idea is that we're going to compress this,
35
115058
2895
κΈ°λ³Έ μ›λ¦¬λŠ” 이것을 μ••μΆ•ν•΄μ„œ

02:00
So there's no motors on board this right now, no power.
37
120654
3383
여기에 λͺ¨ν„°λ‚˜ 동λ ₯은 μ§€κΈˆ μ—†μŠ΅λ‹ˆλ‹€.
02:04
This is actuated with a method that we call in my lab

So what you'll see in the next video

02:11
is this guy doing amazingly well for its jumps.
41

02:14
So this is Aaron, the graduate student in question, with the tweezers,

핀셋을 λ“  λ°”λ‘œ κ·Έ λŒ€ν•™μ›μƒμΈ μ•„λ‘ μΈλ°μš”

and what you see is this four-millimeter-sized mechanism

2683
μ—¬κΈ°μ„œ λ³΄μ‹œλŠ” 4밀리미터 크기의 μž₯μΉ˜κ°€

02:22
That's almost 100 times its own length.
45
142841
2424
02:25
And it survives, bounces on the table,
46
145265
1956
그리고도 λ„λ–‘μ—†μŠ΅λ‹ˆλ‹€. νƒμžμ—μ„œ νŠ•κΉλ‹ˆλ‹€.
02:27
it's incredibly robust, and of course survives quite well until we lose it

02:30
because it's very tiny.
48
150735
2626
λ„ˆλ¬΄ μž‘μœΌλ‹ˆκΉŒμš”. (μ›ƒμŒ)
02:33
Ultimately, though, we want to add motors to this too,

153361
2609
ꢁ극적으둜 μ €ν¬λŠ” 여기에 λͺ¨ν„°λ₯Ό 달고 μ‹ΆμŠ΅λ‹ˆλ‹€.
02:35
and we have students in the lab working on millimeter-sized motors

02:42
But in order to look at mobility and locomotion at this size scale to start,
52
162686
3581
이런 규λͺ¨μ—μ„œ μ›€μ§μ΄λŠ” 이동성을 μ‚΄νŽ΄ 보렀면

we're cheating and using magnets.

02:48
So this shows what would eventually be part of a micro-robot leg,

3076
μ΄ˆμ†Œν˜• λ‘œλ΄‡μ˜ 닀리 뢀뢄이 어떀지 보이싀 κ²λ‹ˆλ‹€.
02:51
and you can see the silicone rubber joints

171317
2017
μ‹€λ¦¬μ½˜ 고무 κ΄€μ ˆμ΄ λ³΄μ΄μ‹œμ£ .
02:53
and there's an embedded magnet that's being moved around
56

2629
거기에 λ‚΄μž₯된 μžμ„μ΄ μ™ΈλΆ€ 자기μž₯에 μ˜ν•΄ 움직이고 μžˆμŠ΅λ‹ˆλ‹€.
02:55
by an external magnetic field.
57
175963
2303
02:58
So this leads to the robot that I showed you earlier.
58
178266
2683
이것이 λ¨Όμ € λ³΄μ—¬λ“œλ¦° λ‘œλ΄‡μœΌλ‘œ μ΄μ–΄μ§‘λ‹ˆλ‹€.
03:01
The really interesting thing that this robot can help us figure out
59

3151
이 λ‘œλ΄‡μ΄ μš°λ¦¬μ—κ²Œ μ•Œλ €μ£ΌλŠ” ν₯미둜운 것은
03:05
is how insects move at this scale.

λ³΄μ—¬μ£ΌλŠ” ν›Œλ₯­ν•œ λͺ¨ν˜•μ΄ μžˆμŠ΅λ‹ˆλ‹€.

We all move in this kind of bouncy way when we run.

But when I'm really small, the forces between my feet and the ground

2775
제 μ§ˆλŸ‰λ³΄λ‹€ λ”μš± 이동성에 영ν–₯을 μ€„κ²λ‹ˆλ‹€.
03:21
which is what causes that bouncy motion.

201288
2354
그것이 νŠ€λŠ” μ›€μ§μž„μ„ μΌμœΌν‚€μ£ .
03:23
So this guy doesn't work quite yet,
67
203642
1675
이 μΉœκ΅¬λŠ” 잘 ν•˜μ§€ λͺ»ν–ˆμ§€λ§Œ
03:25
but we do have slightly larger versions that do run around.

So this is about a centimeter cubed, a centimeter on a side, so very tiny,

3885
ν•œ 변이 1센티미터인 μ•½ 1μž…λ°©μ„Όν‹°λ―Έν„° μ •λ„λ‘œ

03:32
and we've gotten this to run about 10 body lengths per second,
70

2902
이것을 1μ΄ˆμ— 10λͺΈ 길이만큼 λ›°κ²Œ ν–ˆμŠ΅λ‹ˆλ‹€.

κ·ΈλŸ¬λ‹ˆκΉŒ μ΄ˆλ‹Ή 10센티미터인거죠.
03:36
It's pretty quick for a little, small guy,

2033
μ΄λ ‡κ²Œ μž‘μ€ μΉœκ΅¬μ—κ² 무척 λΉ λ₯Έ κ²λ‹ˆλ‹€.
03:38
and that's really only limited by our test setup.
73
218598
2362
이건 μ œν•œμ μΈ μ‹œν—˜ λ‹¨κ³„μ΄κ³ μš”.
03:40
But this gives you some idea of how it works right now.
74

03:44
We can also make 3D-printed versions of this that can climb over obstacles,
75
224027
3754
03:47
a lot like the cockroach that you saw earlier.
76
227781
3499
μž₯애물도 λ„˜μ„ 수 μžˆμŠ΅λ‹ˆλ‹€.
03:51
But ultimately we want to add everything onboard the robot.
77

2886
κ·ΈλŸ¬λ‚˜ μ΅œμ’…μ μœΌλ‘œ μ €ν¬λŠ” λͺ¨λ“  것이 νƒ‘μž¬λœ λ‘œλ΄‡μ„ μ›ν•©λ‹ˆλ‹€.

We want sensing, power, control, actuation all together,

감지, 동λ ₯, ν†΅μ œ, μ›€μ§μž„ μ „λΆ€ ν•¨κ»˜ λ§μž…λ‹ˆλ‹€.

and not everything needs to be bio-inspired.

237859
2906
λͺ¨λ“  것이 생체와 관련될 ν•„μš”λŠ” μ—†μŠ΅λ‹ˆλ‹€.
04:00
So this robot's about the size of a Tic Tac.
80
240765
3135
이 λ‘œλ΄‡μ€ 틱택사탕 μ •λ„μ˜ ν¬κΈ°μž…λ‹ˆλ‹€.
04:03
And in this case, instead of magnets or muscles to move this around,
81
243900
3949
이 κ²½μš°μ—λŠ” μ›€μ§μž„μ„ μœ„ν•œ μžμ„μ΄λ‚˜ κ·Όμœ‘λŒ€μ‹ μ—
04:07
we use rockets.
82
247849
2425
λ‘œμΌ“μ„ μ”λ‹ˆλ‹€.
04:10
So this is a micro-fabricated energetic material,
83
250274
2666
이것은 μ΄ˆμ†Œν˜•μ˜ κ°•λ ₯ν•œ λ¬Όμ§ˆμž…λ‹ˆλ‹€.

and we can create tiny pixels of this,

2599
맀우 μž‘μ€ ν™”μ†Œλ‘œ λ§Œλ“€ 수 μžˆμŠ΅λ‹ˆλ‹€.
04:15
and we can put one of these pixels on the belly of this robot,
85
255539
3787
이 ν™”μ†Œ ν•˜λ‚˜λ₯Ό λ‘œλ΄‡ λ°° μœ„μ— 두면

and this robot, then, is going to jump when it senses an increase in light.

κ³΅μ€‘μ—μ„œ 8μ„Όν‹°λ―Έν„°λ₯Ό λœλ‹ˆλ‹€.
04:32
It's only four by four by seven millimeters in size.

04:34
And you'll see a big flash at the beginning

동λ ₯이 λ“€μ–΄μ˜€λŠ” μ΄ˆκΈ°μ— 큰 λ²ˆμ©μž„μ„ 보싀 κ²λ‹ˆλ‹€.
04:37
when the energetic is set off,

and the robot tumbling through the air.

278622
1908
λ‘œλ΄‡μ΄ κ³΅μ€‘μ—μ„œ κ΅¬λ¦…λ‹ˆλ‹€.
