All About Robots

What is a robot? At its core, a robot is a machine designed to do an activity in place of a person. In science fiction, we imagine humanoid robots that walk, talk, and generally look and act similar to humans. But most robots in the world today look very different.

Robots can be…

  • A Roomba vacuum
  • NASA’s Mars Curiosity rover
  • A remote-controlled toy car or plane
  • A drone, which might carry a camera or package
  • A mechanical arm programmed to build a car, or one that doctors control to perform a surgery

…and much more!
