CL-CoTNav: Closed-Loop Hierarchical Chain-of-Thought for Zero-Shot Object-Goal Navigation with Vision-Language Models
Yuxin Cai, Xiangkun He, Maonan Wang +3
Visual Object Goal Navigation (ObjectNav) requires a robot to locate a target object in an unseen environment using egocentric observations. However, decision-making policies often…
Realm: Real-Time Line-of-Sight Maintenance in Multi-Robot Navigation with Unknown Obstacles
Ruofei Bai, Shenghai Yuan, Kun Li +3
Multi-robot navigation in complex environments relies on inter-robot communication and mutual observations for coordination and situational awareness. This paper studies the multi-…
Multi-Robot Reliable Navigation in Uncertain Topological Environments with Graph Attention Networks
Zhuoyuan Yu, Hongliang Guo, Albertus Hendrawan Adiwahono +4
This paper studies the multi-robot reliable navigation problem in uncertain topological networks, which aims at maximizing the robot team's on-time arrival probabilities in the fac…
Piecewise Linear De-skewing for LiDAR Inertial Odometry
John Henawy, Zhengguo Li, Wei Yun Yau +2
Light detection and ranging (LiDAR) on a moving agent could suffer from motion distortion due to simultaneous rotation of the LiDAR and fast movement of the agent. An accurate piec…
Toward Underground Localization: Lidar Inertial Odometry Enabled Aerial Robot Navigation
Jiun Fatt Chow, Basaran Bahadir Kocer, John Henawy +4
Localization can be achieved by different sensors and techniques such as a global positioning system (GPS), wifi, ultrasonic sensors, and cameras. In this paper, we focus on the la…
Accurate IMU Preintegration Using Switched Linear Systems For Autonomous Systems
John Henawy, Zhengguo Li, Wei Yun Yau +2
Employing an inertial measurement unit (IMU) as an additional sensor can dramatically improve both reliability and accuracy of visual/Lidar odometry (VO/LO). Different IMU integrat…
