RoboticsMicrocomputer-based optical sensor for seam tracking robot

One of the present application of robots in industry is for continous motion along a seam path. The purpose of this paper is to illustrate a microprocessor-based optical sensor for an input or feedback device to guide the robot along a complex 3-dimentional path. A linear array detector was used for fast detection of the seam, and several microprocessors are used to control the robot. The elements of the developed system with performance evaluation data obtained, are presented in this paper.
