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.

Journal of Marine Science and Engineering, 2022 A ship collision risk assessment model is an essential part of ship safety navigation. At present, the open water collision risk assessment model (such as the closest point of approach) is applied, but a ship collision risk model suitable for inland ...

Collision-Avoidance Decision System for Inland Ships Based on Velocity Obstacle Algorithms
Journal of Marine Science and Engineering, 2022 Due to the complex hydrology and narrow channels of inland rivers, ship collision accidents occur frequently. The traditional collision-avoidance algorithms are often aimed at sea areas, and not often at inland rivers. To solve the problem of inland-ship

Analysis of an average velocity of a pipe with flowing fluid in case of a hydraulic obstacle
Lietuvos Matematikos Rinkinys, 2000 Calculation of average velocity of a fluid flow inside a pipe with an asymmetrical obstacle was carried out. Calculations consider flow maximum velocity co-ordinate to move in proportion with the obstacle thickness.
