A robot can be controlled by a human operator, sometimes from a great distance.

A robot can be controlled by a human operator, sometimes from a great distance.

But most robots are controlled by computer, and fall into either of two categories:

autonomous robots and insect robots. An autonomous robot acts as a stand-alone system,

complete with its own computer (called the controller). Insect robots work in fleets

ranging in number from a few to thousands, with all fleet members under the supervision

of a single controller. The term insect arises from the similarity of the system to a

colony of insects, where the individuals are simple but the fleet as a whole can be

sophisticated. Download this very electronic live wallpaper.
