"A robot is a machine that gathers information about its environment and uses that information to follow instructions to do some sort of work." (The Tech Museum of Innovation, 2000) The robot sensory system gathers specific information needed by the control system. The robot control system directs the motion and sensory processing of a robot. The robots mechanical system then produces motion that results in manipulation or locomotion.
Robotics is the science and engineering concerned with the design, manufacture and application of robots, and computer systems for their control, sensory feedback, and information processing. The many types of robotic systems include robotic manipulators, robotic hands, mobile robots, walking robots, aids for disabled persons, tele-robots, and microelectro-mechanical systems. Robotics Engineers study electronics, computer science, artificial intelligence, mechatronics, nanotechnology, and bioengineering.
