Abstract
A robot diagnosing method detects a deviation amount caused by a lost motion and includes: a first step of preparing a robot including a robot arm having at least one joint portion, a work conveyed by the robot, and a prealigner including a processing portion configured to detect a center position of the work; and after the first to fifth steps, a sixth step of detecting the deviation amount caused by the lost motion at the one joint portion based on (i) the center position of the work based on the center position of the work detected in the second step and a command value from a robot control portion in the fourth step and (ii) the center position of the work detected in the fifth step.
