What's our assignment for 00:19.119 --> 00:22.288 align:left position:10% line:85% size:80% science this week? Student 2: We're supposed to 00:22.288 --> 00:24.858 align:left position:10% line:85% size:80% learn about robots. Student 1: Great. 00:24.858 --> 00:27.694 align:left position:10% line:85% size:80% Can you help us learn about robots? 00:27.694 --> 00:32.866 align:left position:10% line:85% size:80% Cartan-Hansen: Robots are human-made machines that perform 00:32.866 --> 00:36.636 align:left position:10% line:85% size:80% work and other actions. Some work automatically. 00:36.636 --> 00:40.673 align:left position:10% line:85% size:80% Some by remote control. Robot comes from the Czech word, 00:40.673 --> 00:43.476 align:left position:10% line:85% size:80% Robotta. It was first used in a play in 00:43.476 --> 00:46.246 align:left position:10% line:85% size:80% the 1920s. Inventors have been building 00:46.246 --> 00:49.115 align:left position:10% line:85% size:80% self-operating machines for centuries. 00:49.115 --> 00:52.318 align:left position:10% line:85% size:80% These automata were run by clocks, or moving water. 00:52.318 --> 00:56.856 position:10% line:85% size:80% The first electronic robots were created in England in the 1940s. 00:56.856 --> 01:01.161 align:left position:10% line:85% size:80% By the 1960s, robots were used to move things around, like in a 01:01.161 --> 01:04.397 align:left position:10% line:85% size:80% car plant. Robots generally have three main 01:04.397 --> 01:07.300 align:left position:10% line:85% size:80% parts. A controller or a brain, this is 01:07.300 --> 01:10.637 align:left position:10% line:85% size:80% the part that tells the robot what to do, or where to go. 01:10.637 --> 01:14.741 align:left position:10% line:85% size:80% Next are the mechanical parts. These are the motors, wheels, 01:14.741 --> 01:18.278 position:10% line:85% size:80% gears, grabbers, whatever, that make the robot do its work to 01:18.278 --> 01:23.049 align:left position:10% line:85% size:80% grab or turn or to lift. The third are the sensors. 01:23.049 --> 01:26.386 position:10% line:85% size:80% These are the devices that allow the robot to figure out size and 01:26.386 --> 01:29.756 align:left position:10% line:85% size:80% space, where to go or how tightly to grip. 01:29.756 --> 01:33.259 align:left position:10% line:85% size:80% Together, these three basic parts make up a robot. 01:33.259 --> 01:37.797 position:10% line:85% size:80% Robots are sometimes used where work is repetitive, that is, the 01:37.797 --> 01:40.800 align:left position:10% line:85% size:80% same task being done over and over again. 01:40.800 --> 01:43.670 align:left position:10% line:85% size:80% They are also used in places that would be dangerous for 01:43.670 --> 01:46.639 align:left position:10% line:85% size:80% people. NASA uses all sorts of different 01:46.639 --> 01:50.944 position:10% line:85% size:80% robots to help us explore space. Rovers on Mars are mini 01:50.944 --> 01:55.248 align:left position:10% line:85% size:80% laboratories helping humans learn about the Martian soil. 01:55.248 --> 01:58.985 align:left position:10% line:85% size:80% These robots at the Johnson Space Center help teach new 01:58.985 --> 02:02.422 align:left position:10% line:85% size:80% astronauts how to do things in space. 02:02.422 --> 02:05.158 align:left position:10% line:85% size:80% Robots come in all shapes and sizes. 02:05.158 --> 02:09.095 align:left position:10% line:85% size:80% Some are as small as insects. These are called nano-bots or 02:09.095 --> 02:12.065 align:left position:10% line:85% size:80% kilobots. Some scientists are designing 02:12.065 --> 02:15.568 align:left position:10% line:85% size:80% robots that show emotion, and some are working on robots that 02:15.568 --> 02:18.872 align:left position:10% line:85% size:80% think. Scientists are just starting to 02:18.872 --> 02:21.841 align:left position:10% line:85% size:80% figure out all the different things robots can do. 02:21.841 --> 02:24.911 align:left position:10% line:85% size:80% So whether they are helping us out at home or traveling deep 02:24.911 --> 02:29.582 position:10% line:85% size:80% into space, robots are changing our lives. 02:29.582 --> 02:31.985 align:left position:10% line:85% size:80% Student 1: Well, that was very interesting. 02:31.985 --> 02:37.790 position:10% line:85% size:80% MiP, stop bothering the Roomba, you know that can't dance. 02:37.790 --> 02:40.693 align:left position:10% line:85% size:80% Cartan-Hansen: If you want to learn more about robotics, check 02:40.693 --> 02:43.363 align:left position:10% line:85% size:80% out the science trek website.
