Communication-Aware Multi-robot Coordination with Submodular Maximization
Guangyao Shi, Ishat E Rabban, Lifeng Zhou +1
Submodular maximization has been widely used in many multi-robot task planning problems including information gathering, exploration, and target tracking. However, the interplay be…
Risk-Aware Submodular Optimization for Multi-objective Travelling Salesperson Problem
Rishab Balasubramanian, Lifeng Zhou, Pratap Tokekar +1
We introduce a risk-aware multi-objective Traveling Salesperson Problem (TSP) variant, where the robot tour cost and tour reward have to be optimized simultaneously. The robot obta…
Robust Multiple-Path Orienteering Problem: Securing Against Adversarial Attacks
Guangyao Shi, Lifeng Zhou, Pratap Tokekar
The multiple-path orienteering problem asks for paths for a team of robots that maximize the total reward collected while satisfying budget constraints on the path length. This pro…
Risk-Aware Planning and Assignment for Ground Vehicles using Uncertain Perception from Aerial Vehicles
Vishnu D. Sharma, Maymoonah Toubeh, Lifeng Zhou +1
We propose a risk-aware framework for multi-robot, multi-demand assignment and planning in unknown environments. Our motivation is disaster response and search-and-rescue scenarios…
Risk-Aware Submodular Optimization for Multi-Robot Coordination
Lifeng Zhou, Pratap Tokekar
We study the problem of incorporating risk while making combinatorial decisions under uncertainty. We formulate a discrete submodular maximization problem for selecting a set using…
