Strategies of locomotor collision avoidance

Strategies for Pre-Emptive Mid-Air Collision Avoidance in Budgerigars

We have investigated how birds avoid mid-air collisions during head-on encounters. Trajectories of birds flying towards each other in a tunnel were recorded using high speed video cameras. Analysis and modelling of the data suggest two simple strategies for collision avoidance: (a) each bird veers to its right and (b) each bird changes its altitude relative to the other bird according to a pres...

Collision Avoidance Strategies for a Three Player Game

Collision avoidance strategies for a game with three players, two pursuers and one evader, are constructed by determining the semi-permeable curves that form the barrier. The vehicles are assumed to have the same capabilities, speed and turn-rates. The game is assumed to be played on a two-dimensional plane. The usable part and its boundary are first determined along with the strategy along the...

Finding aircraft collision-avoidance strategies using policy search methods

Collision avoidance between two walkers: role-dependent strategies.

This paper studies strategies for collision avoidance between two persons walking along crossing trajectories. It has been previously demonstrated that walkers are able to anticipate the risk of future collision and to react accordingly. The avoidance task has been described as a mutual control of the future distance of closest approach, MPD (i.e., Mininum Predicted Distance). In this paper, we...

Collision Avoidance System Proreta - Strategies Trajectory Control and Test Drives

Methods and experimental results of a collision avoidance driver assistance system are described with automatic object detection, trajectory prediction, and path following with controlled braking and steering. The objects are detected by a fusion of LIDAR scanning and video camera pictures resulting in the location, size and speed of objects in front of the car. A desired trajectory is calculat...
