So we looked at the birds,

and we tried to make a model that is powerful, ultralight,

And this was one issue:
18

01:21
to build it that lightweight
19

이것은 ν‘œλ©΄μ„ μ œκ±°ν•œ κ²ƒμž…λ‹ˆλ‹€.
03:13
So here is one without a skin.
37
193084

03:15
We have a wingspan of about two meters.

3211
λ‚ κ°œν­μ€ μ•½ 2m μ •λ„μž…λ‹ˆλ‹€.
03:18
The length is one meter and six,
39
198825
2411
κΈΈμ΄λŠ” 1.06mμž…λ‹ˆλ‹€.
03:21
and the weight is only 450 grams.

λ¬΄κ²ŒλŠ”

03:29
In the middle we have a motor,
42
209260
2459
μ€‘μ•™μ—λŠ” λͺ¨ν„°κ°€ 있고,
03:31
and we also have a gear in it,
43
211743

기어도 λ“€μ–΄ μžˆμŠ΅λ‹ˆλ‹€.
03:35
and we use the gear to transfer the circulation of the motor.

그리고 이 κΈ°μ–΄λŠ”
λͺ¨ν„°μ˜ νšŒμ „λ ₯을 μ „λ‹¬ν•˜λŠ” 데 μ΄μš©λ©λ‹ˆλ‹€.
03:40
So within the motor, we have three Hall sensors,
45

3186
λͺ¨ν„°μ—λŠ” 3개의 ν™€μ„Όμ„œκ°€ 달렀 있으며,
이것듀을 μ΄μš©ν•˜μ—¬ λ‚ κ°œμ˜ μœ„μΉ˜κ°€ μ–΄λ”” μžˆλŠ”μ§€

so we know exactly where the wing is.
46

μ •ν™•νžˆ μ•Œ 수 μžˆμŠ΅λ‹ˆλ‹€.
03:49
And if we now beat up and down --
47

그리고 μ΄λ ‡κ²Œ μœ„μ•„λž˜λ‘œ 움직이면...
03:52
(Mechanical sounds)
48
232735

So if you go down, you have the large area of propulsion,

and if you go up,
51
244425
3087
λ‚ κ°œμ˜ 면적이 쀄어듀며
04:07
the wings are not that large,
52
247536

04:10
and it is easier to get up.

04:18
or the challenges we did,

was to coordinate this movement.

04:23
We have to turn it, go up and go down.
57
263037
3189
이 λ‚ κ°œλ“€μ€ 각기 λ‹€λ₯Έ λΆ€λΆ„μœΌλ‘œ
04:26
We have a split wing.
58

04:27
With the split wing,
59
267810
1426
뢄리 λ˜μ–΄ μžˆμŠ΅λ‹ˆλ‹€.
04:29
we get the lift at the upper wing,

269260
2976
μ–‘λ ₯은 μœ„μͺ½ λ‚ κ°œμ—μ„œ μ–»μœΌλ©°,
04:32
and we get the propulsion at the lower wing.

3214
μΆ”λ ₯은 μ•„λž˜μͺ½ λ‚ κ°œμ—μ„œ μ–»κ²Œ λ©λ‹ˆλ‹€.
04:35
Also, we see how we measure the aerodynamic efficiency.

이제 μ—¬κΈ°λ₯Ό λ³΄μ‹œλ©΄

04:40
We had knowledge about the electromechanical efficiency

곡기역학적 νš¨μœ¨μ„±μ„
μΈ‘μ •ν•˜κΈ° μœ„ν•΄μ„œλŠ”

Next thing we have to do,
67
297581
1859
λ‹€μŒμœΌλ‘œ, 저희가 ν•œ 것은
04:59
we have to control and regulate the whole structure.
