Ground-Effect-Aware Modeling and Control for Multicopters
Tiankai Yang, Kaixin Chai, Jialin Ji +3
The ground effect on multicopters introduces several challenges, such as control errors caused by additional lift, oscillations that may occur during near-ground flight due to exte…
Primitive-Planner: An Ultra Lightweight Quadrotor Planner with Time-optimal Primitives
Jialiang Hou, Neng Pan, Zhepei Wang +4
It is a significant requirement for a quadrotor trajectory planner to simultaneously guarantee trajectory quality and system lightweight. Many researchers focus on this problem, bu…
Fast Iterative Region Inflation for Computing Large 2-D/3-D Convex Regions of Obstacle-Free Space
Qianhao Wang, Zhepei Wang, Mingyang Wang +7
Convex polytopes have compact representations and exhibit convexity, which makes them suitable for abstracting obstacle-free spaces from various environments. Existing generation m…
Adaptive Tracking and Perching for Quadrotor in Dynamic Scenarios
Yuman Gao, Jialin Ji, Qianhao Wang +7
Perching on the moving platforms is a promising solution to enhance the endurance and operational range of quadrotors, which could benefit the efficiency of a variety of air-ground…
Catch Planner: Catching High-Speed Targets in the Flight
Huan Yu, Pengqin Wang, Jin Wang +8
Catching high-speed targets in the flight is a complex and typical highly dynamic task. In this paper, we propose Catch Planner, a planning-with-decision scheme for catching. For s…
