On Segregative Behaviors Using Flocking and Velocity Obstacles [PDF]
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.

Formation-preserving trajectory planning for USV swarms via risk-aware velocity obstacles [PDF]
Maintaining a rigid geometric formation for unmanned surface vehicles (USVs) in real-world waters is challenging, especially when the swarm executes sharp turns or encounters external disturbances.

Test on methane flame velocity in horizontal tube with obstacles
To test flame propagation velocity of gas explosion in a horizontal tube,a set of flame velocity testing system is designed.The system is composed of two parts:a horizontal tube used for methane burning and a flame detection system.The effect of ...

Realtime Multilevel Crowd Tracking Using Reciprocal Velocity Obstacles [PDF]
We present a novel, realtime algorithm to compute the trajectory of each pedestrian in moderately dense crowd scenes. Our formulation is based on an adaptive particle filtering scheme that uses a multi-agent motion model based on velocity-obstacles, and takes into account local interactions as well as physical and personal constraints of each ...

Proactive Collision Avoidance for ASVs using A Dynamic Reciprocal Velocity Obstacles Method
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.

In this paper, we present "IVO: Inverse Velocity Obstacles" an ego-centric framework that improves the real time implementation. The proposed method stems from the concept of velocity obstacle and can be applied for both single agent and multi-agent system. It focuses on computing collision free maneuvers without any knowledge or assumption on the pose

Pedestrian velocity obstacles: pedestrian simulation through reasoning in velocity space
We live in a populous world. Furthermore, as social animals, we participate in activities which draw us together into shared spaces -- office buildings, city sidewalks, parks, events (e.g., religious, sporting, or political), etc. Models that can predict how crowds of humans behave in such settings would be valuable in allowing us to analyze the ...

V-RVO: Decentralized Multi-Agent Collision Avoidance using Voronoi Diagrams and Reciprocal Velocity Obstacles [PDF]
We present a decentralized collision avoidance method for dense environments based on buffered Voronoi cells (BVC) and reciprocal velocity obstacles (RVO).
