ABSTRACT:
In a system for detecting an angle of a joint coupled through a reduction mechanism to a drive motor, an absolute type rotation angle detector and an incremental-type rotation number detector are coupled to the motor for detecting the rotational angle and the rotation number of the motor, respectively. The detected rotational angle and the detected rotation number are used to calculate the rotational angle of the joint. The incremental-type rotation number detector is provided with a battery for energization during interruption of a power supply.
