USS-Nav: Unified Spatio-Semantic Scene Graph for Lightweight UAV Zero-Shot Object Navigation
Weiqi Gai, Yuman Gao, Yuan Zhou +6
Zero-Shot Object Navigation in unknown environments poses significant challenges for Unmanned Aerial Vehicles (UAVs) due to the conflict between high-level semantic reasoning requi…
Number Adaptive Formation Flight Planning via Affine Deformable Guidance in Narrow Environments
Yuan Zhou, Jialiang Hou, Guangtong Xu +1
Formation maintenance with varying number of drones in narrow environments hinders the convergence of planning to the desired configurations. To address this challenge, this paper…
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…
Tracailer: An Efficient Trajectory Planner for Tractor-Trailer Robots in Unstructured Environments
Long Xu, Kaixin Chai, Boyuan An +11
The tractor-trailer robot consists of a drivable tractor and one or more non-drivable trailers connected via hitches. Compared to typical car-like robots, the addition of trailers…
