1. A robot system comprising:
a robot that includes a motor;
a first storage unit comprising a memory that is provided to correspond to the motor and stores identification information of the motor;
a second storage unit comprising a memory that is provided separately from the first storage unit and stores the identification information of the motor; and
a control unit comprising a hardware controller that detects whether or not the motor attached to the robot is a motor to which the identification information has been assigned in advance, by comparing the identification information of the motor stored in the first storage unit and the identification information of the motor stored in the second storage unit, and sets a performance restriction mode in which performance is restricted as compared with performance in a normal operation mode, in response to detecting that the motor is not the motor to which the identification information has been assigned in advance, the performance restriction mode not including stopping the operation of the robot.
