Learning Decentralized Strategies for a Perimeter Defense Game with Graph Neural Networks

Elijah S. Lee, Lifeng Zhou, Alejandro Ribeiro +1

We consider the problem of finding decentralized strategies for multi-agent perimeter defense games. In this work, we design a graph neural network-based learning framework to lear…

Multi-Robot Localization and Target Tracking with Connectivity Maintenance and Collision Avoidance

Rahul Zahroof, Jiazhen Liu, Lifeng Zhou +1

We study the problem that requires a team of robots to perform joint localization and target tracking task while ensuring team connectivity and collision avoidance. The problem can…

Robust Multi-Robot Active Target Tracking Against Sensing and Communication Attacks

Lifeng Zhou, Vijay Kumar

The problem of multi-robot target tracking asks for actively planning the joint motion of robots to track targets. In this paper, we focus on such target tracking problems in adver…

Adaptive and Risk-Aware Target Tracking with Heterogeneous Robot Teams

Siddharth Mayya, Ragesh K. Ramachandran, Lifeng Zhou +2

We consider a scenario where a team of robots with heterogeneous sensors must track a set of hostile targets which induce sensory failures on the robots. In particular, the likelih…

Resilient Coverage: Exploring the Local-to-Global Trade-off

Ragesh K. Ramachandran, Lifeng Zhou James A. Preiss, Gaurav S. Sukhatme

We propose a centralized control framework to select suitable robots from a heterogeneous pool and place them at appropriate locations to monitor a region for events of interest. I…
