In a robot controlling system including a robot unit having a robot arm and a servomotor into which the robot ann is incorporated, a servo amplifier unit to drive the servo motor, and a controlling unit to control the robot arm by sending commands to the servo amplifier unit, and transmit-receive means between the controlling unit and the robot unit is incorporated into transmit-receive means between the controlling unit and the servo amplifier unit as well as into trasmmit-receive means between the servo amplifier unit and the robot unit, transmission and reception between the controlling unit and the robot unit is conducted via the servo amplifier unit. A command to be sent from the controlling unit to the robot unit as well as communication on feedback signals and detection signals to be sent from the robot unit to the controlling unit is conducted via the servo amplifier unit, which as a result may serve to make it possible to omit cables connecting between the control unit and the robot unit, and to decrease in terms of kinds of length of cables and number of cables to be prepared to comply with placement conditions of the controlling unit, the servo amplifier unit, and the robot unit.
