Three-Dimensional Velocity Obstacle Method for UAV Deconflicting Maneuvers
AIAA Guidance, Navigation, and Control Conference, 2015 Autonomous systems are required in order to enable UAVs to conduct self-separation and collision avoidance, especially for flights within the civil airspace system. A method called the Velocity Obstacle Method can provide the necessary situational awareness for UAVs in a dynamic environment, and can help to generate a deconflicting maneuver.This paper ...

Unmanned Surface Vehicle Collision Avoidance Trajectory Planning in an Uncertain Environment
IEEE Access, 2020 Unmanned surface vehicles (USVs) can encounter undetected moving obstacles while sailing along a planned global path. USVs need to plan collision avoidance trajectories for moving obstacles. In this paper, an algorithm based on the Gaussian mixture model

Optimized Dynamic Collision Avoidance Algorithm for USV Path Planning
Sensors, 2023 Ship collision avoidance is a complex process that is influenced by numerous factors. In this study, we propose a novel method called the Optimal Collision Avoidance Point (OCAP) for unmanned surface vehicles (USVs) to determine when to take appropriate ...

Proactive Collision Avoidance for ASVs using A Dynamic Reciprocal Velocity Obstacles Method [PDF]
2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018 We propose a collision avoidance method that incorporates the interactive behavior of agents and is proactive in dealing with the uncertainty of the future behavior of obstacles. The proposed method considers interactions that will be experienced by an autonomous surface vessel (ASV) in an environment governed by the international regulations for ...

Periodic shedding of vortex dipoles from a moving penetrable obstacle in a Bose-Einstein condensate
, 2015 We investigate vortex shedding from a moving penetrable obstacle in a highly oblate Bose-Einstein condensate. The penetrable obstacle is formed by a repulsive Gaussian laser beam that has the potential barrier height lower than the chemical potential of ...
