Characterization of a relatively simple optical sensor used for recognition of the desired fixed trajectory for an automated guided vehicle, painted on an industrial shop floor, is described. The optical sensor consists of 14 infrared emitter-detector pairs arranged in two columns and is fixed underneath the vehicle chassis. A microcomputer-based test platform for evaluation of the proposed sensor is also described. The sensor performance is evaluated using two geometrical algorithms and one based on neural networks, with the latter giving better results.
