A modified dynamic window algorithm for horizontal collision avoidance for AUVs [PDF]
2016 IEEE Conference on Control Applications (CCA), 2016 Much research has been done on the subject of collision avoidance (COLAV). However, few results are presented that consider vehicles with second-order nonholonomic constraints, such as autonomous underwater vehicles (AUVs). This paper considers the dynamic window (DW) algorithm for reactive horizontal COLAV for AUVs, and uses the HUGIN 1000 AUV in a ...

Decentralized constructive collision avoidance for multi-agent dynamical systems [PDF]
2016 European Control Conference (ECC), 2016 This paper describes the principles of a decentralized framework for the guaranteed collision avoidance of Multi-Agent dynamical systems sharing a common working space. The results are constructive and can be effective in the certification of mission safety.

Chance-Constrained Collision Avoidance for MAVs in Dynamic Environments
IEEE Robotics and Automation Letters, 2019 Safe autonomous navigation of microair vehicles in cluttered dynamic environments is challenging due to the uncertainties arising from robot localization, sensing, and motion disturbances. This letter presents a probabilistic collision avoidance method for navigation among other robots and moving obstacles, such as humans.

Pedestrian collision avoidance with a local dynamic goal
Collective Dynamics, 2020 We present here a general formalism for equipping simulated pedestrians with an avoidance mechanism. The central idea is to use a short-range target which is adjusted dynamically depending on the environment and thus modulating the desired velocity of the agent. This formulation can be implemented over any type of existing pedestrian model, being force-

Path planning method with obstacle avoidance for manipulators in dynamic environment
International Journal of Advanced Robotic Systems, 2018 Obstacle avoidance is of great importance for path planning of manipulators in dynamic environment. To help manipulators successfully perform tasks, a method of path planning with obstacle avoidance is proposed in this article.
