Velocity Obstacle Approaches for Multi-Agent Collision Avoidance [PDF]
Unmanned Systems, 2019 This paper presents a critical analysis of some of the most promising approaches to geometric collision avoidance in multi-agent systems, namely, the velocity obstacle (VO), reciprocal velocity obstacle (RVO), hybrid-reciprocal velocity obstacle (HRVO) and optimal reciprocal collision avoidance (ORCA) approaches.

UAV dynamic obstacle avoidance based on improved reciprocal velocity obstacle
Journal of Physics: Conference Series, 2022 Abstract This paper aims to solve the problem that when the UAV flies from the starting point to the target point in the velocity space, the obstacle avoidance speed provided by the mutual velocity obstacle method will appear too large turning angle in order to avoid dynamic obstacles.

On Segregative Behaviors Using Flocking and Velocity Obstacles [PDF]
, 2014 This paper presents a novel approach to swarm navigation that combines hierarchical abstractions, flocking behaviors, and an efficient collision avoidance mechanism. Our main objective is to keep large groups of robots segregated while safely navigating in a shared environment.
