Robot system

A robot system comprising:

• a robot;
• a sensor that detects entry of a person into a peripheral region of the robot;
• and
• a control device that controls the robot and the sensor,
• wherein the control device is provided with:
• a robot control unit that controls the robot on the basis of an operation program;
• an operating-region prediction unit that sequentially predicts an operating region of the robot up to a predetermined time later, on the basis of the operation program;
• and a detection-region control unit that sets to enabled a detection result of the sensor in a region, of the peripheral region, that includes the operating region, which is predicted by the operating-region prediction unit, and sets to disabled a detection result of the sensor in the other region of the peripheral region;
• and
• the robot control unit limits the operation of the robot when entry of a person is detected in the region where the detection result of the sensor has been set to enabled.
