Almost fifty years ago the first industrial robot was "employed" in an automobile assembly plant. Robots are regularly used for hazardous, super-heavy and difficult tasks in manufacturing, agriculture, entertainment, medicine, and space exploration. Welding robots with touch sensing and seam tracking abilities increase assembly plant efficiency, while robotic surgery results in less pain, quicker recovery and shorter hospital stays. NASA's robotic rovers Spirit and Opportunity are mapping the terrain and searching for evidence of water on Mars. Honda Motor Company's humanoid robot, ASIMO, can walk, run, recognize people and identify sounds and voices.
