Multi-Agent Exploration of an Unknown Sparse Landmark Complex via Deep Reinforcement Learning
Xiatao Sun, Yuwei Wu, Subhrajit Bhattacharya +1
In recent years Landmark Complexes have been successfully employed for localization-free and metric-free autonomous exploration using a group of sensing-limited and communication-l…
Pursuer Assignment and Control Strategies in Multi-agent Pursuit-Evasion Under Uncertainties
Leiming Zhang, Amanda Prorok, Subhrajit Bhattacharya
We consider a pursuit-evasion problem with a heterogeneous team of multiple pursuers and multiple evaders. Although both the pursuers (robots) and the evaders are aware of each oth…
Landmark-based Distributed Topological Mapping and Navigation in GPS-denied Urban Environments Using Teams of Low-cost Robots
Mohammad Saleh Teymouri, Subhrajit Bhattacharya
In this paper, we address the problem of autonomous multi-robot mapping, exploration and navigation in unknown, GPS-denied indoor or urban environments using a swarm of robots equi…
Multi-Robot Path Deconfliction through Prioritization by Path Prospects
Wenying Wu, Subhrajit Bhattacharya, Amanda Prorok
This work deals with the problem of planning conflict-free paths for mobile robots in cluttered environments. Since centralized, coupled planning algorithms are computationally int…
Path Homotopy Invariants and their Application to Optimal Trajectory Planning
Subhrajit Bhattacharya, Robert Ghrist
We consider the problem of optimal path planning in different homotopy classes in a given environment. Though important in robotics applications, path-planning with reasoning about…
Approximate Structure Construction Using Large Statistical Swarms
Subhrajit Bhattacharya
In this paper we describe a novel local algorithm for large statistical swarms using "harmonic attractor dynamics", by means of which a swarm can construct harmonics of the environ…
