It is a well-known fact that the position and attitude of an object placed on a plane surface can be precisely adjusted by applying small impacts to its ends. But such a phenomenon has scarcely been applied in automatic control, because an apparatus that can supply appropriately controlled impacts has not been obtained yet. In this research, electromagnetic impulsive force is used for precise positioning. Electromagnetic impulsive force is obtained between a coil and a conductive plate, when an impulsive current flows through the coil. The impulsive current is generated by a discharge circuit. Two different mechanisms are developed for positioning. In the first one, the impulsive force is an external force, and in the other one, the impulsive force is an internal force. The idea has been evaluated through the simulation of motion, and some experiments, and it has been proven that a mass of several kgs can be moved from several nanometers up to several hundred microns by one shot of electric discharge according to the charged energy.
