Generating ExpectedTime Efficient Trajectories for Rapidly Finding an Object in Known Environments (200412)This work addresses the problem of generating a motion strategy for solving a visibilitybased task with a mobile robot equipped with sensors. In particular, the problem is to find a static object  modeled with a probability ...
