D2CoPlan: A Differentiable Decentralized Planner for Multi-Robot Coverage

Vishnu Dutt Sharma, Lifeng Zhou, Pratap Tokekar

Centralized approaches for multi-robot coverage planning problems suffer from the lack of scalability. Learning-based distributed algorithms provide a scalable avenue in addition t…

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…

Resilient Active Target Tracking with Multiple Robots

Lifeng Zhou, Vasileios Tzoumas, George J. Pappas +1

The problem of target tracking with multiple robots consists of actively planning the motion of the robots to track the targets. A major challenge for practical deployments is to m…
