The Convex Uncertain Voronoi Diagram for Safe Multi-Robot Multi-Target Tracking Under Localization Uncertainty

Jun Chen, Philip Dames# (# corresponding author)

Journal of Intelligent & Robotic Systems 2023

In this paper, we introduce the convex uncertain Voronoi (CUV) diagram, a generalization of the standard Voronoi diagram that accounts for the uncertain pose of each individual robot. We then use the CUV diagram to develop distributed multi-target tracking and coverage control algorithms that enable teams of mobile robots to account for bounded uncertainty in the location of each robot.

Distributed Multi-Target Tracking for Heterogeneous Mobile Sensing Networks with Limited Field of Views

Jun Chen, Philip Dames# (# corresponding author)

2021 IEEE International Conference on Robotics and Automation (ICRA) 2021

This paper introduces the normalized unused sensing capacity to measure the amount of information that a sensor is currently gathering relative to its theoretical maximum. This is then used to develop a distributed coverage control strategy for a team of heterogeneous sensors that automatically balances the load based on the current unused capacity of each team member.
