1 00:00:04,300 --> 00:00:05,300 My name is Brian Roberts. 2 00:00:06,000 --> 00:00:09,080 I'm the Head Robotic Technologist here at the Goddard Space Flight Center. 3 00:00:09,080 --> 00:00:10,911 Today, we're going to take a tour of the ROC 4 00:00:10,911 --> 00:00:12,200 or the Robotic Operations Center. 4 00:00:12,760 --> 00:00:16,274 As you enter the ROC, you see a room that's a little bit smaller than a 5 00:00:16,274 --> 00:00:17,373 gymnasium at a school. 6 00:00:17,373 --> 00:00:19,086 You'll notice that the walls are 7 00:00:19,086 --> 00:00:22,170 all black and that's to simulate the darkness of space so we 8 00:00:22,170 --> 00:00:25,880 can shut the lights out in the room and the robots will be 9 00:00:25,880 --> 00:00:27,880 in an environment that will be as dark as it is in space. 10 00:00:28,820 --> 00:00:33,431 So just like sports teams practice before they play a game, we practice with 11 00:00:33,431 --> 00:00:34,420 robots as well. 12 00:00:34,960 --> 00:00:38,615 The first robot you'll hear is our engineering unit of the eventual robot that 13 00:00:38,615 --> 00:00:39,660 will fly in space. 14 00:00:40,300 --> 00:00:43,919 The reason we build that is so we can work out all the details of how to put the 15 00:00:43,919 --> 00:00:44,300 robot together, 16 00:00:45,120 --> 00:00:47,120 make sure it works before we build the more expensive 17 00:00:47,900 --> 00:00:48,700 flight unit. 18 00:00:49,160 --> 00:00:52,360 So the sound you hear sounds like hail hitting a tin roof. 19 00:00:57,480 --> 00:01:00,380 What you'll hear is the brakes on the robot coming on and off. 20 00:01:01,440 --> 00:01:06,094 moving back and forth and you kind of hear a tinging sound as the seven pieces 21 00:01:06,094 --> 00:01:07,840 of metal are hitting each other. 22 00:01:12,400 --> 00:01:14,600 This robot is a hexapod which is a motion platform 23 00:01:15,880 --> 00:01:17,680 on which we mount a satellite mock-up 24 00:01:17,820 --> 00:01:19,620 and the robot then moves that mock-up, 25 00:01:19,960 --> 00:01:22,260 simulating its motion as it would be moving through space. 26 00:01:25,660 --> 00:01:26,760 What you'll hear are 27 00:01:27,260 --> 00:01:31,420 the motors moving back and forth and it kind of sounds like a car engine revving 28 00:01:31,420 --> 00:01:32,460 up and revving down 29 00:01:34,240 --> 00:01:35,340 as you push the gas pedal 30 00:01:36,140 --> 00:01:38,840 and get more acceleration, less acceleration. 31 00:01:38,840 --> 00:01:40,280 You'll hear those motors 32 00:01:40,280 --> 00:01:44,246 moving the six legs of the robot up and down back and forth in front of the 33 00:01:44,246 --> 00:01:44,480 robot. 34 00:01:50,100 --> 00:01:55,793 The last robot you'll hear is an industrial robot that's used by car companies 35 00:01:55,793 --> 00:01:56,200 and 36 00:01:56,740 --> 00:02:01,140 other factories to assemble furniture, assemble cars or paint cars. 37 00:02:03,740 --> 00:02:07,840 So this robot is about the size of a human, maybe six feet or so, 38 00:02:07,840 --> 00:02:11,320 and it's got seven degrees of freedom, so seven individual 39 00:02:11,320 --> 00:02:12,420 actuators that move. 40 00:02:14,820 --> 00:02:19,435 What you'll hear is it moving through our facility and much like the previous 41 00:02:19,435 --> 00:02:20,095 robot, 42 00:02:20,095 --> 00:02:21,491 you'll hear the motors kind of revving up and 43 00:02:21,491 --> 00:02:22,220 revving down. 44 00:02:25,940 --> 00:02:28,697 Thank you for spending some time today touring our Robotic Operations Facility 45 00:02:28,697 --> 00:02:30,765 and listening to some of the robots that we 46 00:02:30,805 --> 00:02:32,440 use to simulate robots working in space.
