Strategies of locomotor collision avoidance [PDF]
Gait & Posture, 2013 Collision avoidance during locomotion can be achieved by a variety of strategies. While in some situations only a single trajectory will successfully avoid impact, in many cases several different strategies are possible. Locomotor experiments in the presence of static boundary conditions have suggested that the choice of an appropriate trajectory is ...

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
