Abstract

A robot diagnosing method of detecting a deviation amount caused by a lost motion includes: a first step of preparing a robot and a line sensor, the robot including a robot arm including one or a plurality of joint portions including a first joint portion, the line sensor including a detecting portion configured to detect a position of a detected portion based on a light receiving state of a light receiver, the detected portion being inserted between a light emitter and the light receiver; and a sixth step of detecting the deviation amount caused by the lost motion at the first joint portion based on (i) the position of the detected portion based on the position of the detected portion detected in a third step and a command value from a robot control portion in a fourth step and (ii) the position of the detected portion detected in a fifth step.
