Robot control system

A robot control system, comprising:

• a robot controller configured to control a robot;
• a first operation device configured to manually operate the robot, the first operation device connected to the robot controller;
• and
• a second operation device configured to manually operate the robot, the second operation device connected to the robot controller,
• wherein each of the first operation device and the second operation device has a request switch configured to switch between a request state in which an operation right for the robot is requested and a non-request state in which the operation right is not requested, and
• the robot controller is configured to:
• start providing the operation right to one of the first operation device and the second operation device only when the request switch of the one of the operation devices is in the request state and the request switch of the other of the operation devices is in the non-request state, allow the one of the operation devices that is granted the operation right to operate the robot and forbids the other of the operation devices from operating the robot while the operation right remains granted to the one of the operation devices, and
• after the operation right is granted to the one of the operation devices, keep the operation right granted without an operation-right setting using a changeover switch which is provided in a device other than the first operation device and the second operation device until the request switch of the one of the operation devices is switched to the non-request state even when the request switch of the other of the operation devices is switched to the request state.
