00:00:00,140 --> 00:00:05,130
NASA is advancing new technology for robots to take care of spacecraft.

2
00:00:05,130 --> 00:00:09,470
The project is called ISAAC,

3
00:00:09,470 --> 00:00:14,430
which stands for Integrated System for Autonomous and Adaptive Caretaking.

4
00:00:14,430 --> 00:00:19,300
The goal is to minimize human supervision

5
00:00:19,300 --> 00:00:24,280
and have robots respond to critical problems when astronauts are away.

6
00:00:24,280 --> 00:00:29,270
Researchers demonstrated how the tech works using Astrobee.

7
00:00:29,270 --> 00:00:34,350
The flying robots aboard the International Space Station can operate autonomously.

8
00:00:34,350 --> 00:00:39,010
They have special cameras and sensors for navigation

9
00:00:39,010 --> 00:00:43,940
and can create 3D maps of their environment.

10
00:00:43,940 --> 00:00:49,120
For the demo, an Astrobee named Bumble was alerted to a simulated danger

11
00:00:49,120 --> 00:00:52,760
and sent to find the problem.

12
00:00:52,760 --> 00:00:56,980
Bumble surveyed the spacecraft with its robot vision.

13
00:00:56,980 --> 00:01:02,140
It found the issue,

14
00:01:02,140 --> 00:01:06,870
a misplaced "sock" blocking an air vent.

15
00:01:06,870 --> 00:01:11,390
The technology will allow for new kinds of human exploration missions in deep space,
