Okay, guys, now let's meet a robotics engineer and learn about some of the different types 00:00:00
of robots being built at NASA. 00:00:05
Thanks, Jen. 00:00:07
My name is Dr. Ayanna Howard here at JPL, NASA's Jet Propulsion Laboratory in California. 00:00:09
This is the Mars Yard, where we actually test the rovers before sending them to Mars. 00:00:14
NASA uses robots to do things that are too dangerous for humans. 00:00:19
Robots are used to explore planets and even maintain and repair the outside of vehicles, 00:00:24
such as the International Space Station. 00:00:29
Hey, guys, did you design your robot to do things that are too dangerous for you to do 00:00:31
or too tedious? 00:00:37
Robots are the tools that allow scientists to reach beyond the Earth to other planets. 00:00:40
In the 1970s, NASA sent a spacecraft to explore the planet Mercury. 00:00:45
It was called the Mariner 10 probe. 00:00:49
It flew past the planet three times and took thousands of photos. 00:00:51
For the first time, scientists could actually see what the surface of the planet looks like. 00:00:55
Rovers are actually robots that can land on other planets and move around. 00:01:02
Sojourner was the first of the rovers to land on the planet Mars. 00:01:06
Its mission was to test the rocks in the air. 00:01:11
It takes several minutes for a command signal to reach a robot in space. 00:01:14
Sometimes a robot can't wait for mission control. 00:01:18
It has to make decisions on its own. 00:01:21
This ability is called autonomy. 00:01:24
Sojourner was semi-autonomous, which means it can make some decisions on its own. 00:01:27
I work on autonomy for Mars exploration. 00:01:32
We want to land precisely where there are good samples to study. 00:01:35
We want to be careful so we don't hit any cliffs or boulders on the surface of Mars. 00:01:38
We can use airbags, but we can't land precisely. 00:01:43
That's why we use artificial intelligence. 00:01:47
Not only can we use artificial intelligence to land the spacecraft safely on Mars, but 00:01:50
we can use the same intelligence to give the rovers a little bit more smarts when they 00:01:55
actually get to the surface. 00:01:59
The future of space exploration depends on building these smart robots. 00:02:03
Thank you, Dr. Howard. 00:02:10
Okay, guys. 00:02:11
Let's head over to the NASA Ames Research Center here in California to learn more about 00:02:12
robots from researcher Maria Bullitt. 00:02:16
What a cool robot! 00:02:19
Tell me about K-9. 00:02:21
K-9 is a prototype of a Mars exploration rover with stereo cameras so it can take 3D pictures, 00:02:22
and it's got an arm that lets us practice putting science instruments on rocks and on 00:02:29
soil. 00:02:33
Okay, Maria, so how will K-9 know what to do on Mars? 00:02:34
It will receive instructions from Earth on what experiments to conduct. 00:02:38
A robot's shape, capabilities, and method of locomotion depend on what you want it to 00:02:42
do. 00:02:45
Besides K-9, what other robots does NASA have? 00:02:47
We're testing planetary robots in the Rio Tinto, or Red River region of Spain, where 00:02:50
the terrain looks a lot like the surface of Mars. 00:02:55
That robot is built to burrow into the ground and look for signs of life. 00:02:58
Robots are also being built to maintain and repair the outside of a space vehicle. 00:03:01
Robonaut is a humanoid robot that performs tasks that other robots can't. 00:03:06
From the safety of the space station, an astronaut controls the movement of Robonaut's hands 00:03:10
with a control system known as telepresence. 00:03:14
Aircam is another experimental robot that's being designed to fly outside a space station 00:03:17
and lets astronauts inside see what's going on outside. 00:03:21
Scientists are also designing robots to help us out here on Earth. 00:03:25
Gizmet, the sociable robot. 00:03:28
Aww, did he say he loves me? 00:03:30
I love you too. 00:03:34
Scientists at MIT are working on building a robot that can interact with people. 00:03:36
So there are many different kinds of robots that are designed to work in many different 00:03:39
environments. 00:03:44
That's right. 00:03:45
Robots may need parts that can see, parts that enable them to move around, and parts 00:03:46
that make decisions. 00:03:49
All these parts must work together for the robot to function. 00:03:50
They make up a mechanical system. 00:03:53
Thanks Maria. 00:03:55
So, can you think of a mechanical system? 00:03:56
Remember, a mechanical system is something that's made up of many different parts, and 00:03:59
those parts work together so the system will function. 00:04:04
Now it's time for your teacher to pause the program and for you to answer the following 00:04:08
questions. 00:04:12
What is a mechanical system? 00:04:13
And what are some examples of mechanical systems? 00:04:15
