The human collaboration robot have attracted in recent year. The proximity sensor on the robot is important for safety. In this paper, we propose a ToF (Time-of-Flight) and capacitance combined proximity sensor for human collaboration robot. ToF sensor can detect the distance between the sensor and an object. However, the detection accuracy in close proximity range is reduced. On the other hand, the self-capacitance proximity sensor can detect object before contact, and the sensitivity in close proximity range is high. Proximity measurement with high sensitivity and wide range is possible to combine ToF sensor and self-capacitance sensor. Thus, this proximity sensor will assure the safety and workability of the robot.
