robot

A robot is a machine, usually programmable by a computer, that can carry out many actions automatically.

 

Robots can be guided by a remote control or the control may be programmed inside the robot itself. Robots may be constructed to take on human form but most robots are machines designed to perform a task with no regard to how they look.

Robots can be autonomous (work on their own) and range from ones that look like humans (such as Honda's Advanced Step in Innovative Mobility) to industrial robots that are used in factories, medical operating robots, swarm robotsdrones and even microscopic nano robots.

 

The branch of technology that deals with designing and making robots is called robotics. These people deal with robots that can take the place of humans in dangerous environments.
