This proceedings volume documents recent cutting-edge developments in  multi-robot systems research. This volume is the result of the Third  International workshop on Multi-Robot Systems that was held in March  2005 at the Naval Research Laboratory in Washington, D.C. This workshop  brought together top researchers working in areas relevant to designing  teams of autonomous vehicles, including robots and unmanned ground, air,  surface, and undersea vehicles. The workshop focused on the challenging  issues of team architectures, vehicle learning and adaptation,  heterogeneous group control and cooperation, task selection, dynamic  autonomy, mixed initiative, and human and robot team interaction.
