A '''robot''' is a programmable machine with many functions, such as building [[automobiles]] or cleaning floors (as is the case with the Roomba). In science fiction, robots often are servants to the sentients of that galaxy.

In science fiction, robots often are servants to the sentients of that galaxy. While this may be entertaining, [[artificial intelligence]] has proved much more difficult to develop than initially thought.  

*"'''HOW ROBOTS WORK''': Robots are made of roughly the same components as human beings: a body structure with moveable joints; a muscle system outfitted with motors and actuators to move that body structure; a sensory system to collect information from the surrounding environment; a power source to activate the body; and a computer "brain" system to process sensory information and tell the muscles what to do. Robots are manmade machines intended to replicate human and animal behavior. Roboticists can combine these basic elements with other technological innovations to create some very complex robotic systems."
