Abstract
A robot system includes a motor provided at a joint, a regenerative resistor that consumes a back electromotive force generated by rotation of the motor as heat, and a controller configured or programmed to predict a life of the regenerative resistor based on a period of time during which the regenerative resistor is consuming heat.
