UWB Radar SLAM: an Anchorless Approach in Vision Denied Indoor Environments
H. A. G. C. Premachandra, Ran Liu, Chau Yuen +1
LiDAR and cameras are frequently used as sensors for simultaneous localization and mapping (SLAM). However, these sensors are prone to failure under low visibility (e.g. smoke) or…
Exploiting Radio Fingerprints for Simultaneous Localization and Mapping
Ran Liu, Billy Pik Lik Lau, Khairuldanial Ismail +6
Simultaneous localization and mapping (SLAM) is paramount for unmanned systems to achieve self-localization and navigation. It is challenging to perform SLAM in large environments,…
Clustering and Analysis of GPS Trajectory Data using Distance-based Features
Zann Koh, Yuren Zhou, Billy Pik Lik Lau +3
The proliferation of smartphones has accelerated mobility studies by largely increasing the type and volume of mobility data available. One such source of mobility data is from GPS…
Multi-AGV's Temporal Memory-based RRT Exploration in Unknown Environment
Billy Pik Lik Lau, Brandon Jin Yang Ong, Leonard Kin Yung Loh +4
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…
Distributed Ranging SLAM for Multiple Robots with Ultra-WideBand and Odometry Measurements
Ran Liu, Zhongyuan Deng, Zhiqiang Cao +6
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)…
NLOS Ranging Mitigation with Neural Network Model for UWB Localization
Muhammad Shalihan, Ran Liu, Chau Yuen
Localization of robots is vital for navigation and path planning, such as in cases where a map of the environment is needed. Ultra-Wideband (UWB) for indoor location systems has be…
