Robot control device and numerical control system

A numerical control system comprising:

• a robot control device which controls operation of a robot system including a robot and a mobile body to which the robot is equipped;
• and
• a numerical control device including a first processor which is communicably connected with the robot control device and controls operation of a machine tool provided within an operation range of the robot system based on a numerical control program,
• wherein the robot control device includes a second processor configured to execute instructions to implement:
• a storage unit that stores a plurality of programs establishing the machine tool and the numerical control device as a manipulation target and prescribed for every operation of the robot system on the manipulation target,
• a state acquisition unit that acquires a state of the manipulation target,
• an analysis unit that analyzes a state acquired by the state acquisition unit,
• a program selection activation unit that selects and activates a program according to an analysis result by the analysis unit from among a plurality of programs stored in the storage unit, and
• an operation control unit that controls operation of the robot system based on a program activated by the program selection activation unit, and
• wherein the robot system includes a motion sensor that detects presence of a person within the operation range, and
• the operation control unit controls operation of the robot under a cooperation mode in a case where the presence of a person is detected within the operation range by the motion sensor, and controls operation of the robot under a high-speed mode with a faster operation speed than the cooperation mode in a case where the presence of a person is not detected within the operation range by the motion sensor.
