Robotic Locating System

Abstract

The Robotic Locating System (RLS) is a multisensor laboratory test bed designed to evaluate the feasibility of measuring target range and orientation in various robotic environments. The targets are considered to be cooperative and typically have LEDs or reflective material placed on them. Laser illumination in combination with video sensing is the primary sensor system. A pair of optical position sensors and an array of ultrasonic ranging sensors to augment system performance. This paper will report on the sensitivity study being done to determine the resolution and accuracy of the measurement process. In particular, details of measuring all six degrees of freedom (DOF) of a rectangular target with four LEDs or four spots of reflective tape will be presented.
