Abstract:
This robot diagnosis method is characterized by the inclusion of: a first step of preparing a robot comprising a robot arm having at least one joint part, and a detection target part moving as one body with a wrist part from the robot arm, and preparing a line sensor containing a light projector for projecting a light beam, a light receiver for receiving the light beam projected from the light projector, and a detection unit for detecting, based on the light reception state at the light receiver, the position of the detection target part inserted between the light projector and the light receiver; a second step of operating, based on the command values from a robot control unit, the wrist part to travel rectilinearly in such a manner as to intersect with the light beam, while detecting the position of the detection target part with the line sensor; and a third step of diagnosing, based on the position of the detection target part detected in the second step, the rectilinear travelling ability of the wrist part.
