Autonomous Tail-Sitter Flights in Unknown Environments
Guozheng Lu, Yunfan Ren, Fangcheng Zhu +5
Trajectory generation for fully autonomous flights of tail-sitter unmanned aerial vehicles (UAVs) presents substantial challenges due to their highly nonlinear aerodynamics. In thi…
Swarm-LIO2: Decentralized, Efficient LiDAR-inertial Odometry for UAV Swarms
Fangcheng Zhu, Yunfan Ren, Longji Yin +8
Aerial swarm systems possess immense potential in various aspects, such as cooperative exploration, target tracking, search and rescue. Efficient, accurate self and mutual state es…
Trajectory Generation and Tracking Control for Aggressive Tail-Sitter Flights
Guozheng Lu, Yixi Cai, Nan Chen +3
We address the theoretical and practical problems related to the trajectory generation and tracking control of tail-sitter UAVs. Theoretically, we focus on the differential flatnes…
Online Whole-body Motion Planning for Quadrotor using Multi-resolution Search
Yunfan Ren, Siqi Liang, Fangcheng Zhu +2
In this paper, we address the problem of online quadrotor whole-body motion planning (SE(3) planning) in unknown and unstructured environments. We propose a novel multi-resolution…
