A robot may need senses like these to manage its operation. Processors that Process Living creatures have brains and nervous systems that perform amazing feats of processing so they can understand the information collected by their senses. Robots may use computers or electronic circuits as brains . The frontiers of artificial intelligence and machine learning have many discoveries to make before robots can match the abilities of even simple living creatures. Just as living creatures use muscles to move, to make noise and to interact, robots need ways to move too.
Robots generally perform tasks too dangerous or tedious for humans.
Robotic arms, for example, help build cars. Once programmed through a computer, the robotic arms do their job reliably every time. Sojourner rover which explored Mars in 1996 could drive around or over unexpected objects without human input. That s a good thing too, since radioed commands needed several minutes to reach Sojourner from Earth. In futuristic movies, robots sometimes try to destroy their human creators.
