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…
Reactive Aerobatic Flight via Reinforcement Learning
Zhichao Han, Xijie Huang, Zhuxiu Xu +5
Quadrotors have demonstrated remarkable versatility, yet their full aerobatic potential remains largely untapped due to inherent underactuation and the complexity of aggressive man…
Shape-Adaptive Planning and Control for a Deformable Quadrotor
Yuze Wu, Zhichao Han, Xuankang Wu +4
Drones have become essential in various applications, but conventional quadrotors face limitations in confined spaces and complex tasks. Deformable drones, which can adapt their sh…
Model-Based Planning and Control for Terrestrial-Aerial Bimodal Vehicles with Passive Wheels
Ruibin Zhang, Junxiao Lin, Yuze Wu +5
Terrestrial and aerial bimodal vehicles have gained widespread attention due to their cross-domain maneuverability. Nevertheless, their bimodal dynamics significantly increase the…
Ring-Rotor: A Novel Retractable Ring-shaped Quadrotor with Aerial Grasping and Transportation Capability
Yuze Wu, Fan Yang, Ze Wang +4
This letter presents a novel and retractable ring-shaped quadrotor called Ring-Rotor that can adjust the vehicle's length and width simultaneously. Unlike other morphing quadrotors…
