ROBOT SYSTEM AND ROBOT OPERATION METHOD

The present invention addresses the issue of providing a robot system and a robot operation method whereby, even if an issue occurs with an EOAT (a tool attached to the tip of a robot arm) and repair is required during application processing work by a robot, that repair does not take a lot of time or effort, errors do not occur during restoration work, and the restoration can be conducted quickly. This issue is solved by the present invention being configured so as to enable application processing work to be resumed by a user program that had been interrupted, after: returning back along the path recorded during progress by the robot tool; causing the tool to exit the work region; removing the cause of the error; then moving forward again along the recorded tool path to return to the point at which the error occurred.
