  • Publication number: 20210039264
    Abstract: A robot system and method for controlling a robot, wherein during learning, a detection unit detects, as waveform data for learning, the contact state when a socket is caused to contact a set position of the head of a bolt and is caused to rotate around the set position within a set movement range. A learning unit learns a plurality of detected sets of the waveform data for learning and writes the learning results to a determination unit. During practical operations, the determination unit recognizes the amount that the socket slips with respect to the bolt on the basis of actual waveform data indicating the change in the contact state when the socket is in contact with the head of the bolt and the written learning results.
