A Comparison between CARS and ROMUM based on Human Interface Technology

Abstract

This research compared CARS based on a computer system and ROMUM based on manual operation to measure the robot work. Time, accuracy, and usability of the analysis were selected as an evaluation index. In general, even though test results showed that the difference of the analysis time and the rate of error between computer work (CARS) and manual work (ROMUM) increased as the difficulty increased, there was not a certain linear relationship between these two works. This research discussed CARS developed as a computer supported system to measure the work time of a robot by attempting human-interface aspect to substitute the manual work measurement method based on PTS. The CARS was constructed as computer supported user oriented menu-driven type by taking advantage of ROMUM techniques. Therefore, compare to existing analytical method based on detailed basic motion, CARS could pursue the usability for user by selecting a module of unit motion according to the work content, minimize the analysis effort, and prevent errors as an effective work measurement system. Also, it might recognize unnecessary motion in advance and prevent execution of unnecessary motion by employing the analysis method according to the work content
