Abstract
This paper presents a method for planning the motions of a mobile robot navigating in a known environment with uncertainty in control and sensing. The robot is equipped with sensors which, if properly used, may provide information to overcome the uncertainty accumulated during the motions. The planner produces robust motion strategies composed of sensor-based motion commands which guarantee that the robot can reach the goal with an error lower than a pre-specified value. Relocalizations can occur in landmark regions or by matching detected features of the environment against the workspace model. The approach is based on a numerical potential field function for propagating the position uncertainty. A geometric analysis of the workspace is also performed in order to generate relocalization strategies on obstacles. We present at the end of the paper several examples run with the planner illustrating some of its capabilities.
