withstand and report on its journey to

7
00:00:59,520 --> 00:00:57,250
the floor of a volcano NASA sponsored a

8
00:01:02,130 --> 00:00:59,530
team from Carnegie Mellon University to

9
00:01:04,070 --> 00:01:02,140
build Dante a robot designed to

10
00:01:07,889 --> 00:01:04,080
withstand Earth's harshest conditions

11
00:01:11,400 --> 00:01:07,899
its goal proved up technology to explore

12
00:01:14,100 --> 00:01:11,410
distant planets remotely controlled from

13
00:01:15,050 --> 00:01:14,110
80 miles away the robot was able to

14
00:01:27,980 --> 00:01:15,060
explore

15
00:01:29,630 --> 00:01:27,990
a fundamental purpose that our program

16
00:01:31,999 --> 00:01:29,640
is interested in is is the robotics

17
00:01:34,100 --> 00:01:32,009
technology itself in the ability of a

18
00:01:36,050 --> 00:01:34,110
robotic instrument to go and do this

19
00:01:37,940 --> 00:01:36,060
type of mission in a harsh unstructured

20
00:01:46,899 --> 00:01:37,950
environment that can deliver a science

21
00:01:52,520 --> 00:01:49,660
scientists an anchorage 80 miles away

22
00:01:55,010 --> 00:01:52,530
from their remote location controllers

23
00:01:57,529 --> 00:01:55,020
use the computer-generated image created

24
00:02:00,410 --> 00:01:57,539
by a laser scanner to track its movement

25
00:02:02,419 --> 00:02:00,420
educate yes having accomplished one

26
00:02:04,380 --> 00:02:02,429
short-term goal with the successful

27
00:02:06,390 --> 00:02:04,390
descent in the bomb

28
00:02:08,850 --> 00:02:06,400
the robot team hopes to apply the

29
00:02:11,820 --> 00:02:08,860
lessons learned to NASA's long-term

30
00:02:13,800 --> 00:02:11,830
plans for the future our hope is that a

31
00:02:15,180 --> 00:02:13,810
lot of that will find its way into

32
00:02:17,250 --> 00:02:15,190
future planetary missions that's

33
00:02:19,350 --> 00:02:17,260
obviously where NASA's interest lies is

34
00:02:21,060 --> 00:02:19,360
we want to take this and move it out to

35
00:02:56,170 --> 00:02:21,070
the surface of other heavenly bodies the

36
00:03:00,729 --> 00:02:58,809

withstand and report on its journey to

42
00:03:27,770 --> 00:03:24,530
Nasr sponsored a team from carnegie

43
00:03:30,050 --> 00:03:27,780
mellon university to build Dante a robot

44
00:03:32,780 --> 00:03:30,060
designed to withstand Earth's harshest

45
00:03:41,320 --> 00:03:32,790
conditions its goal proved out

46
00:03:46,940 --> 00:03:44,480
remotely controlled from 80 miles away

47
00:03:53,530 --> 00:03:46,950
robot was able to investigate the inner

48
00:04:01,640 --> 00:03:57,140
of steaming vents surrounded by sheer

49
00:04:03,230 --> 00:04:01,650
walls and fractured there's everything

50
00:04:06,500 --> 00:04:03,240
from pebbles to car-sized boulders

51
00:04:08,000 --> 00:04:06,510
rolling down all day long we tried to

52
00:04:10,640 --> 00:04:08,010
pick a descent course that would protect

53
00:04:29,900 --> 00:04:10,650
insulate the machine from most of the

54
00:04:35,909 --> 00:04:33,029
one of the robots function was division

55
00:04:38,159 --> 00:04:35,919
levels of volcanic gases this

56
00:04:40,860 --> 00:04:38,169
information gives Mike deepness of the

57
00:04:44,189 --> 00:04:40,870
Alaska Volcano Observatory an idea of

58
00:04:46,320 --> 00:04:44,199
how active the crater might be it has

59
00:04:49,770 --> 00:04:46,330
gas sensors onboard as a software sensor

60
00:04:52,189 --> 00:04:49,780
at carbon dioxide sensors and so that's

61
00:04:55,740 --> 00:04:52,199
going to give us a real close in view

62
00:05:08,520 --> 00:04:55,750
and sampling of what the fumaroles are

63
00:05:10,890 --> 00:05:08,530
made of if you are in the wrong place at

64
00:05:13,290 --> 00:05:10,900
the wrong time the person standing next

65
00:05:14,730 --> 00:05:13,300
to you will die and you won't and so

66
00:05:17,070 --> 00:05:14,740
it's a matter of you have to ask that

67
00:05:19,830 --> 00:05:17,080
question why are you going in to that

68
00:05:21,149 --> 00:05:19,840
zone is it necessary for you to go into

69
00:05:29,300 --> 00:05:21,159
that zone can you do that same

70
00:05:35,520 --> 00:05:32,190
because of the ever-present danger of an

71
00:05:37,770 --> 00:05:35,530
explosion scientists monitored seismic

72
00:05:43,500 --> 00:05:37,780
activity and kept constant radio contact

73
00:05:45,930 --> 00:05:43,510
with the team on the crater rim in 1993

74
00:05:49,440 --> 00:05:45,940
the first donned a robot attempted to

75
00:05:51,840 --> 00:05:49,450
explore Mount Erebus in Oaxaca when its

76
00:05:54,810 --> 00:05:51,850
fiber-optic communications cable snapped

77
00:05:57,630 --> 00:05:54,820
the mission was cut short but according

78
00:06:00,840 --> 00:05:57,640
to CMU's John bears the mission taught

79
00:06:02,820 --> 00:06:00,850
them some valuable lesson we looked at

80
00:06:05,820 --> 00:06:02,830
the experience from daunting one which

81
00:06:07,320 --> 00:06:05,830
taught us an awful lot about what would

82
00:06:09,210 --> 00:06:07,330
work what wouldn't work what was

83
00:06:11,190 --> 00:06:09,220
appropriate for the environment what was

84
00:06:13,290 --> 00:06:11,200
appropriate for the terrain what was

85
00:06:14,850 --> 00:06:13,300
appropriate to take on in a year and

86
00:06:19,980 --> 00:06:14,860
then we came here and looked at the

87
00:06:22,650 --> 00:06:19,990
volcano to improve its systems major

88
00:06:25,560 --> 00:06:22,660
design changes had to be made quickly to

89
00:06:27,390 --> 00:06:25,570
keep the project on schedule it was done

90
00:06:31,020 --> 00:06:27,400
with the help of experts in laser

91
00:06:37,100 --> 00:06:31,030
technology telecommunications computer

92
00:06:42,210 --> 00:06:39,900
after power was supplied to the robot

93
00:06:43,350 --> 00:06:42,220
from a generator and all communications

94
00:06:47,040 --> 00:06:43,360
links were set

95
00:06:56,000 --> 00:06:47,050
Dante was ready I think we're ready to

96
00:07:10,550 --> 00:06:59,160
the eight-legged crap began its assault

97
00:07:23,499 --> 00:07:14,370
at 90 metres special rubber snowshoes

98
00:07:29,839 --> 00:07:26,839
ultimately Dandi spent 3 and 1/2 days

99
00:07:32,540 --> 00:07:29,849
traversing the nearly 700 feet down to

100
00:07:48,520 --> 00:07:32,550
the crater floor an area covered with

101
00:07:53,749 --> 00:07:51,260
information from onboard video cameras

102
00:07:58,520 --> 00:07:53,759
and sensors was relayed the assent light

103
00:08:04,130 --> 00:08:01,610
from their remote location controllers

104
00:08:07,090 --> 00:08:04,140
use the concur generated image created

105
00:08:09,950 --> 00:08:07,100
by a laser scanner to track its movement

106
00:08:12,050 --> 00:08:09,960
in addition they had a computer display

107
00:08:14,510 --> 00:08:12,060
that was in effect the robots dashboard

108
00:08:17,600 --> 00:08:14,520
that gave them information and feedback

109
00:08:18,830 --> 00:08:17,610
from all the onboard sensor systems told

110
00:08:20,390 --> 00:08:18,840
them when the legs were in contact when

111
00:08:23,120 --> 00:08:20,400
the ground what angle the legs were

112
00:08:24,440 --> 00:08:23,130
positioned at what attitude the body had

113
00:08:27,190 --> 00:08:24,450
with respect to gravity in the ground

114
00:08:30,650 --> 00:08:27,200
that sort of information

115
00:08:34,459 --> 00:08:30,660
David Lavery is manager of NASA's Teller

116
00:08:37,159 --> 00:08:34,469
robotics program Dante also incorporates

117
00:08:40,430 --> 00:08:37,169
virtual reality technology developed at

118
00:08:43,120 --> 00:08:40,440
NASA Ames Research Center the system

119
00:08:45,680 --> 00:08:43,130
gives the user a feeling of being there

120
00:08:48,260 --> 00:08:45,690
what it is is a pair of cameras that are

121
00:08:51,770 --> 00:08:48,270
set at the human ocular distance roughly

122
00:08:54,230 --> 00:08:51,780
that and then those cameras frames from

123
00:08:57,260 --> 00:08:54,240
those images are sequenced back at the

124
00:09:00,170 --> 00:08:57,270
operator station using a special monitor

125
00:09:05,810 --> 00:09:00,180
and a special glasses so that the human

126
00:09:08,150 --> 00:09:05,820
is able to perceive some depth this same

127
00:09:11,660 --> 00:09:08,160
technology has been tested in a number

128
00:09:14,360 --> 00:09:11,670
of applications by NASA Martian Rover

129
00:09:17,210 --> 00:09:14,370
prototypes and underwater explorers have

130
00:09:22,379 --> 00:09:17,220
been operated remotely using 3d visual

131
00:09:28,150 --> 00:09:25,059
artificial intelligence allowed dumpee

132
00:09:31,269 --> 00:09:28,160
to navigate on its own a lot of what we

133
00:09:33,910 --> 00:09:31,279
learned had to do with how much autonomy

134
00:09:36,369 --> 00:09:33,920
can be used onboard a robot given our

135
00:09:38,379 --> 00:09:36,379
current level of technology to navigate

136
00:09:40,900 --> 00:09:38,389
through the extremely rugged terrain

137
00:09:42,939 --> 00:09:40,910
that we saw inside the crater we had a

138
00:09:45,249 --> 00:09:42,949
capability for at least half of the

139
00:09:46,809 --> 00:09:45,259
descent to basically turn on all of the

140
00:09:48,780 --> 00:09:46,819
onboard intelligence on the robot and

141
00:09:51,069 --> 00:09:48,790
let it do its own thing

142
00:09:53,889 --> 00:09:51,079
although the extremely treacherous

143
00:09:56,530 --> 00:09:53,899
terrain impeded Dante's climb from the

144
00:09:59,049 --> 00:09:56,540
crater all science and technology

145
00:10:00,759 --> 00:09:59,059
objectives were completed indicating

146
00:10:04,059 --> 00:10:00,769
that the crater will probably remain

147
00:10:06,429 --> 00:10:04,069
inactive it proved that exploring

148
00:10:10,629 --> 00:10:06,439
dangerous terrain was possible using

149
00:10:13,480 --> 00:10:10,639
unaided robotic technology CMU graduate

150
00:10:16,869 --> 00:10:13,490
student Demetrius apostille Ovilus it's

151
00:10:18,730 --> 00:10:16,879
becoming almost like a life goal every

152
00:10:21,519 --> 00:10:18,740
single person who got involved in in

153
00:10:24,280 --> 00:10:21,529
both projects has made their decisions

154
00:10:27,730 --> 00:10:24,290
to try to make something happen and make

155
00:10:29,919 --> 00:10:27,740
it known to the outside world having

156
00:10:31,660 --> 00:10:29,929
accomplished one short-term goal with

157
00:10:34,329 --> 00:10:31,670
the successful descent into mount

158
00:10:36,939 --> 00:10:34,339
spurred the robot team hopes to apply

159
00:10:40,119 --> 00:10:36,949
the lessons learned to NASA's long-term

160
00:10:42,129 --> 00:10:40,129
plans for the future our hope is that a

161
00:10:43,449 --> 00:10:42,139
lot of that will find its way into

162
00:10:45,549 --> 00:10:43,459
future planetary missions that's

163
00:10:47,530 --> 00:10:45,559
obviously where NASA's interest lies is

164
00:10:49,389 --> 00:10:47,540
we want to take this and move it out to

165
00:10:57,340 --> 00:10:49,399
the surface of other heavenly bodies to

166
00:11:52,560 --> 00:11:12,090
you

167
00:11:52,570 --> 00:13:06,100
just get the wires out we can use them

168
00:13:10,509 --> 00:13:08,619
in addition they had a computer display

169
00:13:13,299 --> 00:13:10,519
that was in effect the robots dashboard

170
00:13:16,359 --> 00:13:13,309
that gave them information and feedback

171
00:13:17,619 --> 00:13:16,369
from all the onboard sensor systems told

172
00:13:19,350 --> 00:13:17,629
them when the legs were in contact when

173
00:13:22,150 --> 00:13:19,360
the ground what angle the legs were

174
00:13:23,919 --> 00:13:22,160
positioned at what what attitude the

175
00:13:28,119 --> 00:13:23,929
body had with respect to gravity in the

176
00:13:30,939 --> 00:13:28,129
ground that sort of information a lot of

177
00:13:33,699 --> 00:13:30,949
what we learned had to do with how much

178
00:13:36,100 --> 00:13:33,709
autonomy can be used on board a robot

179
00:13:38,259 --> 00:13:36,110
given our current level of technology to

180
00:13:40,720 --> 00:13:38,269
navigate through the extremely rugged

181
00:13:43,030 --> 00:13:40,730
terrain that we saw inside the crater we

182
00:13:45,369 --> 00:13:43,040
had a capability for at least half of

183
00:13:46,809 --> 00:13:45,379
the descent to basically turn on all of

184
00:13:50,759 --> 00:13:46,819
the onboard intelligence on the robot

185
00:13:55,509 --> 00:13:53,590
and our hope is that a lot of that will

186
00:13:57,039 --> 00:13:55,519
find its way into future planetary

187
00:13:58,780 --> 00:13:57,049
