Abstract


Planning under uncertainty faces a scalability problem when
considering multi-robot teams, as the information space scales
exponentially with the number of robots. To address this issue,
this paper proposes to decentralize multi-robot Partially Observable
Markov Decision Processes (POMDPs) while maintaining cooperation
between robots by using POMDP policy auctions. Auctions provide a
flexible way of coordinating individual policies modeled by POMDPs
and have low communication requirements. Additionally,
communication models in the multi-agent POMDP literature severely
mismatch with real inter-robot communication. We address this issue
by exploiting a decentralized data fusion method in order to
efficiently maintain a joint belief state among the robots.
The paper presents results in two different applications: environmental monitoring
with Unmanned Aerial Vehicles (UAVs); and cooperative tracking, in which
several robots have to jointly track a moving target of interest.
