Capability-Aware Task Allocation and Team Formation Analysis for Cooperative Exploration of Complex Environments

摘要

To achieve autonomy in complex real-world exploration missions, we consider deployment strategies for a team of robots with heterogeneous capabilities. We formulate a multi-robot exploration mission and compute an operation policy to maintain robot team productivity and maximize mission success. The environment description, robot capability, and mission outcome are modeled as a Markov decision process (MDP). We also include constraints, such as sensor failures, limited communication coverage, and mobility-stressing elements. The proposed operation model is applied to the DARPA Subterranean (SubT) Challenge. The deployment policy is also compared against the human-based operation strategy in the final competition of the SubT Challenge.
