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.

Motion planner of mobile robots for obstacles in occluded areas
Nihon Kikai Gakkai ronbunshu, 2019 Motion planning for mobile robots considering occluded obstacles is a navigation challenge in dynamic environments. If an obstacle suddenly appears from the occluded area, a robot might collide with the obstacle. This is the occlusion problem. Therefore,

Obstacle Boundary Point and Expected Velocity‐Based Flocking of Multiagents with Obstacle Avoidance
International Journal of Intelligent Systems, 2023 Obstacle avoidance is a key technology of multiagents flocking control. However, most existing research studies assume that the agent can obtain global information about obstacles and have specific constraints on the shape and boundary of obstacles, which easily limit their practical applications.
