Vehicle Safety of the Velocity Obstacle Algorithm [PDF]
2020 59th IEEE Conference on Decision and Control (CDC), 2020 This paper presents a mathematical analysis of the velocity obstacle algorithm applied to a nonholonomic vehicle for avoiding a moving obstacle in the plane. The velocity obstacle algorithm can be used for local navigation among dynamic obstacles by continually computing a set of unsafe velocities, and avoid the velocities inside of this set.

The Hybrid Reciprocal Velocity Obstacle [PDF]
IEEE Transactions on Robotics, 2011 We present the hybrid reciprocal velocity obstacle for collision-free and oscillation-free navigation of multiple mobile robots or virtual agents. Each robot senses its surroundings and acts independently without central coordination or communication with other robots.

Velocity Obstacle Based 3D Collision Avoidance Scheme for Low-Cost Micro UAVs
Sustainability, 2017 An unmanned aerial vehicle (UAV) must be able to safely reach its destination even, when it can only gather limited information about its environment. When an obstacle is detected, the UAV must be able to choose a path that will avoid collision with the ...

Generalized Velocity Obstacles
2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009We address the problem of real-time navigation in dynamic environments for car-like robots. We present an approach to identify controls that will lead to a collision with a moving obstacle at some point in the future. Our approach generalizes the concept of velocity obstacles, which have been used for navigation among dynamic obstacles, and takes into ...

Avoidance of High-Speed Obstacles Based on Velocity Obstacles
2018 IEEE International Conference on Robotics and Automation (ICRA), 2018For obstacles moving with high speeds, existing motion planning methods can rarely guarantee collision avoidance. This paper proposes a viable two-period velocity obstacle algorithm where one period predicts potential collisions within a limited time horizon, and the second period foresees collisions beyond that horizon.
