Swashplateless-elevon Actuation for a Dual-rotor Tail-sitter VTOL UAV
Nan Chen, Fanze Kong, Haotian Li +6
In this paper, we propose a novel swashplateless-elevon actuation (SEA) for dual-rotor tail-sitter vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAVs). In contrast…
Snapp: An Agile Robotic Fish with 3-D Maneuverability for Open Water Swim
Timothy J. K. Ng, Nan Chen, Fu Zhang
Fish exhibit impressive locomotive performance and agility in complex underwater environments, using their undulating tails and pectoral fins for propulsion and maneuverability. Re…
Perch a quadrotor on planes by the ceiling effect
Yuying Zou, Haotian Li, Yunfan Ren +5
Perching is a promising solution for a small unmanned aerial vehicle (UAV) to save energy and extend operation time. This paper proposes a quadrotor that can perch on planar struct…
Occupancy Grid Mapping without Ray-Casting for High-resolution LiDAR Sensors
Yixi Cai, Fanze Kong, Yunfan Ren +3
Occupancy mapping is a fundamental component of robotic systems to reason about the unknown and known regions of the environment. This article presents an efficient occupancy mappi…
Bubble Explorer: Fast UAV Exploration in Large-Scale and Cluttered 3D-Environments using Occlusion-Free Spheres
Benxu Tang, Yunfan Ren, Fangcheng Zhu +4
Autonomous exploration is a crucial aspect of robotics that has numerous applications. Most of the existing methods greedily choose goals that maximize immediate reward. This strat…
Tight Collision Probability for UAV Motion Planning in Uncertain Environment
Tianyu Liu, Fu Zhang, Fei Gao +1
Operating unmanned aerial vehicles (UAVs) in complex environments that feature dynamic obstacles and external disturbances poses significant challenges, primarily due to the inhere…
ROG-Map: An Efficient Robocentric Occupancy Grid Map for Large-scene and High-resolution LiDAR-based Motion Planning
Yunfan Ren, Yixi Cai, Fangcheng Zhu +2
Recent advances in LiDAR technology have opened up new possibilities for robotic navigation. Given the widespread use of occupancy grid maps (OGMs) in robotic motion planning, this…
ImMesh: An Immediate LiDAR Localization and Meshing Framework
Jiarong Lin, Chongjiang Yuan, Yixi Cai +5
In this paper, we propose a novel LiDAR(-inertial) odometry and mapping framework to achieve the goal of simultaneous localization and meshing in real-time. This proposed framework…
