1
00:00:00,750 --> 00:00:04,780
The robot consists of two snowmobile tracks and two solar panels.

2
00:00:04,800 --> 00:00:06,280


3
00:00:06,300 --> 00:00:12,170
It's not a robot for the sake of building a robot. But it's a robot for science.

4
00:00:12,190 --> 00:00:15,210


5
00:00:15,230 --> 00:00:18,250
The climate is changing and snow is really important

6
00:00:18,270 --> 00:00:23,280
because it reflects a lot of the energy and heat from the sun.

7
00:00:23,300 --> 00:00:28,300
Places like Greenland which are covered in snow are very important.

8
00:00:28,320 --> 00:00:32,330
It's a large area of the earth's surface that's reflecting energy.

9
00:00:32,350 --> 00:00:34,350


10
00:00:34,370 --> 00:00:40,400
Our main concern and main motivation to come over here was to be able to test it in the extreme environment,

11
00:00:40,420 --> 00:00:45,370
and temperature is definitely one of the most difficult issues.

12
00:00:45,390 --> 00:00:49,510
One thing is to be testing it in a controlled environment

13
00:00:49,530 --> 00:00:54,530
in a university, and a completely different thing is to come up here.

14
00:00:54,550 --> 00:00:58,570


15
00:00:58,590 --> 00:01:08,650
When you get up here at -30 Celsius the wires, they just break in the cold, their so brittle.

16
00:01:08,670 --> 00:01:13,660


17
00:01:13,680 --> 00:01:16,730
Biggest challenge was definitely trying to 

18
00:01:16,750 --> 00:01:20,100
solve problems in the field. 

19
00:01:20,120 --> 00:01:24,860
Out here when something breaks five miles out in the middle of the ice,

20
00:01:24,880 --> 00:01:28,890
it's very difficult to get the tools out and stay warm

21
00:01:28,910 --> 00:01:31,230
enough to be able to perform the repairs.

22
00:01:31,250 --> 00:01:36,960
We had to kinda go in shifts, work for a little bit, and then put your hands

23
00:01:36,980 --> 00:01:40,180
back in the gloves, or swing them, or put them in your armpits, or something.

24
00:01:40,200 --> 00:01:42,300
Warm them up, take a break.

25
00:01:42,320 --> 00:01:48,020
A repair that would take 10 minutes in normal conditions in a warehouse or a shop,

26
00:01:48,040 --> 00:01:53,110
it would take hours out there.

27
00:01:53,130 --> 00:01:57,180
What else could it be?

28
00:01:57,200 --> 00:02:01,240
Quick test - backwards first.

29
00:02:01,260 --> 00:02:05,300


30
00:02:05,320 --> 00:02:10,360
Yes, we could have failed but we made it.

31
00:02:10,380 --> 00:02:13,400
It was kind of magic, to see it happen

32
00:02:13,420 --> 00:02:19,120
to see GROVER moving, every single time he went. It was great.

33
00:02:19,140 --> 00:02:22,840
GROVER represents the ability to collect an enormous amount of data. 

34
00:02:22,860 --> 00:02:26,170
It would really revolutionize how much information 

35
00:02:26,190 --> 00:02:29,490
we can get about the ice sheet on Greenland.

36
00:02:29,510 --> 00:02:33,540
It's really important to track the changes here.

37
00:02:33,560 --> 00:02:37,590


38
00:02:37,610 --> 00:02:41,630


39
00:02:41,650 --> 00:02:53,020
