Abstract: This thesis investigates the use of multiple mobile sensors to guide the motion of a distributed manipulation system. In our system, multiple robots cooperatively place a large object at a goal in a dynamic, unstructured, unmapped environment. We take the system developed in [Rus, Kabir, Kotay, Soutter 1996], which employs a single mobile sensor for navigational tasks, and extend it to allow the use of multiple mobile sensors. This allows the system to perform successful manipulations in a larger class of spaces than was possible in the single scout model. We focus on the development of a negotiation protocol that enables multiple scouts to cooperatively plan system motion. This algorithm enhances the previous' system's scalability and adds greater fault-tolerance. Two alternate algorithms for cooperation: a modification of negotiation and a bidding protocol, are also discussed. Finally, an implementation of the negotiation protocol is described and experimental data produced by the implementation is analyzed.
