  1. A human has a skeleton, and a robot has a body or frame. Humans have eyes and ears, and many robots have sensory systems, which take in information about the environment. A computer controls and directs the robot's movements, similar to a human brain. Like a human arm, a robotic arm uses joints that can pivot in different directions. Robotic limbs move with the expansion and contraction of pistons, which are much like our muscles. Humans survive with the help of lungs, circulatory systems and digestive tracts, while robots need electrical power, and often pressurized pumps for hydraulic or pneumatic valves.
