Role Definition and Task Allocation for a Cooperative EVA and Robotic Team 2009-01-2529

Employing a cooperative human and robotic team has the potential to greatly reduce human workload during space missions and create more efficient operational teams. The Hubble Space Telescope Servicing Mission 3A tasks were assessed and modeled with three different human and robot team pairings to elucidate the difference to team performance. Tasks were allocated to the standard two-human EVA crew and a robotic agent for each of the cases. The schedules reduce the human crew's involvement time in each EVA day's activities by rearranging subtasks to minimize the human crew's wait time. This work examines three agent participation scenarios and their effect on the expected efficiency of the cooperative team during mission activities.
