WEBVTT FILE 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
