Abstract: A proximity detection system includes a proximity sensor that is a capacitive sensor mounted on a mounting position on a robot, the proximity sensor being configured to detect proximity between the mounting position and an object; and a shield signal output unit configured to apply a shield signal for preventing the proximity sensor from detecting proximity of another position of the robot other than the mounting position.
