We study the following multi-robot coordination problem: given a graph, where each edge is weighted by the probability of surviving while traversing it, find a set of paths for K robots that maximizes the expected number of nodes collectively visited, subject to constraints on the probabilities that each robot survives to its destination. We call this the Team Surviving Orienteers (TSO) problem, which...
Consider a setting where robots must visit sites represented as nodes in a graph, but each robot may fail when traversing an edge. The goal is to find a set of paths for a team of robots which maximizes the expected number of nodes collectively visited, while guaranteeing that the paths satisfy a notion of “independence” formalized by a matroid (e.g. limits on team size, number of visits to regions),...

Collaborative beamforming promises important advantages for networks of power-constrained nodes. Realizing these gains requires significant levels of synchronization among transmitters which limits the applications of the technology and increases complexity. This paper considers a selection combining approach to relax synchronization requirements for intercluster beamforming. Simulations demonstrate...
