Technology of Robot is a new technology which has developed rapidly for about 30 years. It delegates the tiptop achievement of the system of mechanics and electronics.
The machinist can imitate the manpower and arm's certain holding function, with by presses the fixed routine to capture, the transporting thing 'OR' operation tool's automatic operation installment. It may replace person's strenuous labor to realize the production mechanization and the automation, can operate under the hostile environment protects the personal safety, thus widely applies in departments and so on machine manufacture, metallurgy, electron, light industry and atomic energy.The whole system is composed of manipulator hand, manipulator arm, joints and stepper motor driving system. By stepper motor’s driving of each degree of freedom, it completes location change of manipulator hand and manipulator arm.particularlydiscusses principle of mechanism,design of hardware interface,and programme of software
