This proceedings volume documents recent cutting-edge developments in multi-robot systems research. This volume is the result of a workshop on Multi-Robot Systems that was held in March 2002 at the Naval Research Laboratory in Washington, D.C. This workshop was held as part of the NATO working group IST-032/RTG-014 on Multi-Robot Systems and preceded this group's formal meeting. 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.
