Multi-Robot Collaborative SLAM (Multi-SLAM) With Distributed Lightweight Predictive Frontier Exploration (LPFE)

RA-L 2026

Autonomous mobile robot systems have been extremely useful in exploration tasks for inspection and surveying of unknown environments, where map quality and exploration speed are often important factors. To effectively increase the exploration speed, multi-robot systems and collaborative exploration

Target Localization and Following Based on LiDAR and Ultra-Wideband Ranging with Consideration of Target Visibility

IROS 2025

To perform target-following tasks in unknown environments, a robot must identify the target’s position and plan an efficient path to reach it. Traditional LiDAR-based localization systems face challenges in distinguishing the target from objects with similar appearances. Meanwhile, existing target-f

Distributed Ranging SLAM for Multiple Robots with Ultra-WideBand and Odometry Measurements

IROS 2022poster

To accomplish task efficiently in a multiple robots system, a problem that has to be addressed is Simultaneous Localization and Mapping (SLAM). LiDAR (Light Detection and Ranging) has been used for many SLAM solutions due to its superb accuracy, but its performance degrades in featureless environmen…

Multi-AGV's Temporal Memory-Based RRT Exploration in Unknown Environment

RA-L 2022

With the increasing need for multi-robot for exploring the unknown region in a challenging environment, efficient collaborative exploration strategies are needed for achieving such feat. A frontier-based Rapidly-Exploring Random Tree (RRT) exploration can be deployed to explore an unknown environmen
