1
00:00:00,000 --> 00:00:03,000
Nice to meet you, Mr. Wozzeck.

2
00:00:03,000 --> 00:00:04,000
Nice meeting you.

3
00:00:04,000 --> 00:00:06,000
This is a wind tunnel, isn't it?

4
00:00:06,000 --> 00:00:08,000
What do you do here?

5
00:00:08,000 --> 00:00:10,000
We're testing a new kind of airplane.

6
00:00:10,000 --> 00:00:14,000
A micro air vehicle, or MAV for short.

7
00:00:14,000 --> 00:00:16,000
Is this a real plane?

8
00:00:16,000 --> 00:00:19,000
It looks more like a bird or a bat or something.

9
00:00:19,000 --> 00:00:20,000
Well, you're pretty close.

10
00:00:20,000 --> 00:00:22,000
It's about the size of a bird.

11
00:00:22,000 --> 00:00:26,000
And we use what we know about how birds, bats, and insects fly to help design it.

12
00:00:26,000 --> 00:00:28,000
Do you test your models?

13
00:00:28,000 --> 00:00:30,000
Yes, testing is an important part of the design process.

14
00:00:30,000 --> 00:00:33,000
That's why we're here, to learn more about the design process.

15
00:00:33,000 --> 00:00:37,000
Well, design is the process by which you turn ideas into reality.

16
00:00:37,000 --> 00:00:40,000
Ideas often involve contributions from many different people.

17
00:00:40,000 --> 00:00:45,000
We collaborate or work together by sharing ideas to improve our design.

18
00:00:45,000 --> 00:00:46,000
Kind of like us.

19
00:00:46,000 --> 00:00:48,000
We work together as a team.

20
00:00:48,000 --> 00:00:49,000
We collaborate.

21
00:00:49,000 --> 00:00:50,000
That's great.

22
00:00:50,000 --> 00:00:53,000
For MAVs, we're working with aerodynamicists, controls engineers,

23
00:00:53,000 --> 00:00:56,000
wind tunnel engineers, technicians, and even biologists.

24
00:00:56,000 --> 00:00:57,000
Biologists?

25
00:00:57,000 --> 00:00:58,000
That's right.

26
00:00:58,000 --> 00:01:00,000
Biologists help to better understand how animals fly.

27
00:01:00,000 --> 00:01:03,000
And we can design and build airplanes that use the same principles.

28
00:01:03,000 --> 00:01:07,000
Through collaboration, we help each other, and we can iterate to get a better design.

29
00:01:07,000 --> 00:01:08,000
Iter what?

30
00:01:08,000 --> 00:01:09,000
Iterate.

31
00:01:09,000 --> 00:01:13,000
It almost always takes lots of tries and retries before you get an effective design.

32
00:01:13,000 --> 00:01:18,000
Iteration refers to the process by which we design, build, test, and analyze our data.

33
00:01:18,000 --> 00:01:22,000
Data collection is another part of the scientific process.

34
00:01:22,000 --> 00:01:24,000
From our data, we modify our design.

35
00:01:25,000 --> 00:01:28,000
We repeat the process over and over again until we get it right.

36
00:01:28,000 --> 00:01:32,000
So collaboration and iterative design help you come up with this.

37
00:01:32,000 --> 00:01:35,000
But what are you going to do with such a small plane?

38
00:01:35,000 --> 00:01:38,000
Well, we're going to use it to be our eyes and other senses

39
00:01:38,000 --> 00:01:41,000
to go to places we can't get to or are too dangerous to go.

40
00:01:41,000 --> 00:01:43,000
That is so awesome.

41
00:01:43,000 --> 00:01:47,000
I guess we need to get back to the tree house so we can collaborate and iterate.

42
00:01:47,000 --> 00:01:48,000
That's right.

43
00:01:48,000 --> 00:01:50,000
And remember to use what you learn to make your designs better.

44
00:01:50,000 --> 00:01:52,000
Thank you very much, Mr. Wozak.

45
00:01:52,000 --> 00:01:53,000
This was really great.

46
00:01:53,000 --> 00:01:54,000
Oh, yeah. Thanks a lot.

47
00:01:54,000 --> 00:01:55,000
See you.

48
00:01:55,000 --> 00:01:56,000
Bye.
