Paper Abstract

An angular scan triangulation range sensor using an integrated array of light-emitting diodes (LEDs) and a lateral-effect position-sensing detector is described in the paper. A range map is obtained by means of fast electronic scanning of the LEDs of the array. No moving parts are needed for the scanning. The sensor output is a set of object surface coordinates or other parameters describing the shape, size and position of the object. A compact version of the sensor was manufactured and tested to perform angle measurements and surface profile determination for obstacle detection and collision avoidance in the blasting robot applications. Based on the experimental tests of the sensor within the range 0.2 - 2 m, it is found that the performance of the sensor is sufficient for many applications in profile measurement and obstacle detection in robotics and machine automation.
