Robots and automata
A robot is a computer-programmed machine, that performs actions, manipulates objects in a precise and, in many cases, repetitive way.
Robots can be automata, or man-like machines, whose components are similar to a human body.
They have mechanical links, joints, which connect their movable parts.
Their heart and muscles are the electric or pneumatic motors or systems, the actuators, which create the movement.
Robots also have hands, usually tools or grippers, called end effectors.
They can be equipped with camera or infrared control, sensors, which transmit information to the central system in order to locate objects or adjust movements.
Finally, robots depend on a computer system, the brain that directs the actions.

Scientists are working on a machine which they hope will recognize objects with cameras that will work as
