Development of Teaching Material for Robot Mechanisms Applying Projection Mapping Technology

Abstract

Teaching materials that can interactively display the vectors of forces and velocities as well as the trajectories and graphs of remarkable points, which are invisible in actual mechanical movements, should be capable of effectively supporting the learning of complex robot mechanics. In this study, we aim to acquire knowledge about the design principles for building teaching materials for robot mechanics, applying projection mapping technology (PM). We have first studied the components required in teaching material systems on the following candidate mechanisms: transmission mechanism with spur gears and quadric crank chain as two basic mechanisms and serial two-link mechanism as a representative subject of robot mechanisms. We have constructed systems and conducted experiments to evaluate their performance. In this study, we propose a fundamental method for designing teaching materials on mechanisms applying PM, establish the effectiveness of the proposed method, and indicate problems with the current systems.
