Robust Trajectory Planning for Spatial-Temporal Multi-Drone Coordination in Large Scenes
Zhepei Wang, Chao Xu, Fei Gao
In this paper, we describe a robust multi-drone planning framework for high-speed trajectories in large scenes. It uses a free-space-oriented map to free the optimization from cumb…
STD-Trees: Spatio-temporal Deformable Trees for Multirotors Kinodynamic Planning
Hongkai Ye, Chao Xu, Fei Gao
In constrained solution spaces with a huge number of homotopy classes, stand-alone sampling-based kinodynamic planners suffer low efficiency in convergence. Local optimization is i…
Meeting-Merging-Mission: A Multi-robot Coordinate Framework for Large-Scale Communication-Limited Exploration
Yuman Gao, Yingjian Wang, Xingguang Zhong +6
This letter presents a complete framework Meeting-Merging-Mission for multi-robot exploration under communication restriction. Considering communication is limited in both bandwidt…
Distributed Swarm Trajectory Optimization for Formation Flight in Dense Environments
Lun Quan, Longji Yin, Chao Xu +1
For aerial swarms, navigation in a prescribed formation is widely practiced in various scenarios. However, the associated planning strategies typically lack the capability of avoid…
Elastic Tracker: A Spatio-temporal Trajectory Planner Flexible Aerial Tracking
Jialin Ji, Neng Pan, Chao Xu +1
This paper proposes Elastic Tracker, a flexible trajectory planning framework that can deal with challenging tracking tasks with guaranteed safety and visibility. Firstly, an objec…
GPA-Teleoperation: Gaze Enhanced Perception-aware Safe Assistive Aerial Teleoperation
Qianhao Wang, Botao He, Zhiren Xun +2
Gaze is an intuitive and direct way to represent the intentions of an individual. However, when it comes to assistive aerial teleoperation which aims to perform operators' intentio…
