This paper presents the ROBOT MODAPTS(Modular Arrangement of Predetermi- ned Time Standards) technique which can be applied to the robot motion analysis. Robot motions are easily divided into several movement activities and terminal activi- ties by means of the ROBOT MODAPTS technique Each link of robot arm is numbered such that finger is 1, hand is 2, elbow is 3, and so on. The robot motion time of each link is counted by multipling its given number to some time values observed at the finger movement. We can easily estimate robot teaching task time with this technique. This technique can be applied efficiently to establishing an adaptable robot motion ergonomically.
