The Mechanical Arm

The mechanical arm is the means used by the robot to move its end effector to the desired points, in a manner similar to that of the human arm. Since most of today’s robots are stationary, the arm is generally the only part of the robot that moves. In the future, with mobile robots coming into use, it is possible that additional parts — such as artificial legs — will be called upon to execute motions. This will require the use of mechanical legs (or wheels), additional motors, and the robot “brain” capable of controlling the motion of the mechanical legs as well as that of the arm (arms).
