Another message can be sent to the robot s arms and the robot moves its arms. Robots can be programmed to do many kinds of work. They can fold themselves in half, and turn their heads clear around. Other robots are used for dangerous tasks, such as disarming bombs. Outer space is another place robots can work.
Automobile manufacturers use robots in crash tests.
They are also used to test firefighting equipment and clothing and space suits. Once a robot is correctly programmed, it can perform tasks on its own. However, the robot must always be programmed by a person, so it is never totally independent. They have arms, legs, a head and a body. Other robots are only an arm or hand, if that is all that is necessary to perform their work.
