SLAM: Decentralized and Distributed Collaborative Visual-inertial SLAM System for Aerial Swarm
Hao Xu, Peize Liu, Xinyi Chen +1
Collaborative simultaneous localization and mapping (CSLAM) is essential for autonomous aerial swarms, laying the foundation for downstream algorithms such as planning and control.…
RACER: Rapid Collaborative Exploration with a Decentralized Multi-UAV System
Boyu Zhou, Hao Xu, Shaojie Shen
Although the use of multiple Unmanned Aerial Vehicles (UAVs) has great potential for fast autonomous exploration, it has received far too little attention. In this paper, we presen…
Neither Fast Nor Slow: How to Fly Through Narrow Tunnels
Luqi Wang, Hao Xu, Yichen Zhang +1
Nowadays, multirotors are playing important roles in abundant types of missions. During these missions, entering confined and narrow tunnels that are barely accessible to humans is…
BDPGO: Balanced Distributed Pose Graph Optimization Framework for Swarm Robotics
Hao Xu, Shaojie Shen
Distributed pose graph optimization (DPGO) is one of the fundamental techniques of swarm robotics. Currently, the sub-problems of DPGO are built on the native poses. Our validation…
Control of a Tail-Sitter VTOL UAV Based on Recurrent Neural Networks
Jinni Zhou, Hao Xu, Zexiang Li +2
Tail-sitter vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAVs) have the capability of hovering and performing efficient level flight with compact mechanical struct…
Omni-swarm: A Decentralized Omnidirectional Visual-Inertial-UWB State Estimation System for Aerial Swarms
Hao Xu, Yichen Zhang, Boyu Zhou +4
Decentralized state estimation is one of the most fundamental components of autonomous aerial swarm systems in GPS-denied areas yet it still remains a highly challenging research t…
Decentralized Visual-Inertial-UWB Fusion for Relative State Estimation of Aerial Swarm
Hao Xu, Luqi Wang, Yichen Zhang +2
The collaboration of unmanned aerial vehicles (UAVs) has become a popular research topic for its practicability in multiple scenarios. The collaboration of multiple UAVs, which is…
EU H2020 Gauss project. Geo-Fencing Software System
Hao Xu
The Geofencing system is the key to operate the Unmanned Aerial Vehicle (UAV) within the safe and appropriate zone to avoid public concerns and other privacy issues. The system is…
