Abstract
A robot includes: links, connected in series to a base via joints; actuators, driving the joints to relatively displace a corresponding pair of links connected to each other; control devices, distributedly arranged in the base and the links and controlling the actuators; a communication cable, comprising an optical fiber connecting the control devices to each other and transmitting information; and light amount measurement devices, measuring the amount of light of an optical signal transmitted to the control devices via the communication cable. Each control device monitors the amount of light measured by the light amount measurement device corresponding thereto, and determines a state of the communication cable corresponding thereto based on the amount of light.
