This paper describes some experiments in sensor-based mobile robot navigation conducted at Oak Ridge National Laboratory over the past several years. Two implemented systems are described. One uses a laser range camera as the sole sensor. The other uses, in addition, an array of sonars and a stereo vision system. We discuss a communication system for heterogeneous LAN-connected multiprocessor systems, useful in reasonably large development projects such as these. We also describe some work on the estimation of curvature in range images which introduces a new variational principle motivated by minimization of the change of curvature. Application of this principle is shown to produce results which are more desirable in some respects than those obtained using standard quadratic variation.
