Distributed Relative Localization Based on Ultra-WideBand and LiDAR for Multi-robot with Limited Communication

Zhiqiang Cao, Ran Liu, Billy Pik Lik Lau et al. · 2026

Relative localization is crucial for a multi-robot system to collaboratively perform tasks, such as exploration and formation. However, this is highly challenging for homogeneous robots with similar appearance in GPS-denied and communication-limited environments. In this paper, we propose a fully distributed relative p …

Distributed Relative Localization for Homogeneous Multi-Robot Systems through UWB Ranging and Limited Communications

Zhiqiang Cao, Ran Liu, Billy Pik Lik Lau et al. · 2026

Accurate and reliable relative localization is crucial for multi-robot applications like exploration, search, and rescue missions. LiDAR-based solutions offer high accuracy in localizing surrounding objects; however, distinguishing homogeneous robots with similar appearances remains challenging due to the lack of disti …
