An improved time discretized non-linear velocity obstacle method for multi-ship encounter detection
Ocean Engineering, 2020Abstract Ship collision is one of the major contributors of maritime accidents. Quantitative risk analysis of such accidents is an effective tool for maritime safety administrations to understand the current risk level and propose risk mitigation measures. In this paper, an improved Time Discretized Non-linear Velocity obstacle (TD-NLVO) algorithm is

Velocity obstacle–based conflict resolution and recovery method
The Aeronautical Journal, 2021ABSTRACTConsidering the shortcomings of current methods for real-time resolution of two-aircraft flight conflicts, a geometric optimal conflict resolution and recovery method based on the velocity obstacle method for two aircraft and a cooperative conflict resolution method for multiple aircraft are proposed.

Traffic Regulation Velocity Obstacles method
2019 20th International Carpathian Control Conference (ICCC), 2019The goal of this paper is to show a new concept of the reactive motion planning algorithms for mobile robots in dynamic environment using the main rules of the Traffic Regulation. At the presented solution the algorithm uses the velocity vectors and positions of the obstacles and the robot so the Velocity Obstacles (VO) method seems to be a good choice

Cooperative conflict resolution by velocity obstacle method
2014 UKACC International Conference on Control (CONTROL), 2014© 2014 IEEE. Automated and more efficient methods for resolution of conflicts between aircraft are necessary to support the sustained growth of air traffic. Distributed optimization is one of the proposed conflict resolution methods which can improve efficiency; but, sometimes it imposes an unequal burden on involved agents.

Development of an optimal velocity selection method with velocity obstacle
Journal of Mechanical Science and Technology, 2015The Velocity obstacle (VO) method is one of the most well-known methods for local path planning, allowing consideration of dynamic obstacles and unexpected obstacles. Typical VO methods separate a velocity map into a collision area and a collision-free area.

Three-Dimensional Velocity Obstacle Method for UAV's Uncoordinated Avoidance Maneuver
AIAA Guidance, Navigation, and Control Conference, 2016This paper proposes a novel avoidance method called the Three-Dimensional Velocity Obstacle (3DVO) method. The method is designed for Unmanned Aerial Vehicle (UAV) applications, in particular to autonomously handle uncoordinated encounters in an integrated airspace, by exploiting the limited space in a three-dimensional manner.

The curvature-velocity method for local obstacle avoidance
Proceedings of IEEE International Conference on Robotics and Automation, 2002We present a new method for local obstacle avoidance by indoor mobile robots that formulates the problem as one of constrained optimization in velocity space. Constraints that stem from physical limitations (velocities and accelerations) and the environment (the configuration of obstacles) are placed on the translational and rotational velocities of ...

Motion planning for mobile robots using the safety velocity obstacles method
2018 19th International Carpathian Control Conference (ICCC), 2018The main purpose of our work was to develop and implement a motion planning algorithm that can ensure the avoidance of static and moving obstacles in the workspace of the robot. We used the Velocity Obstacles method, which is suitable for motion planning of mobile robots in a dynamic environment.

Hybrid Motion Planner Integrating Global Voronoi Diagrams and Local Velocity Obstacle Method
2018 European Control Conference (ECC), 2018Global and local path planning are a classic research field in robotics and are key elements for the development of automated warehouse. Velocity Obstacle (VO) and Voronoi Diagrams (VD) are well known methods in autonomous navigation. VO provides for each autonomous vehicle a set of available velocities ensuring collision-free trajectory for multi ...
