Ship Collision Avoidance Based on the Vulnerability Assessment for Small Vessels in Bad Weather

open access: yesIEEE Access, 2023
In the conditions of bad weather, the small vessels maneuvering ability of collision avoidance is seriously reduced and the vulnerability to maritime accidents increases due to the influence of strong wind and wave.

Reactive collision avoidance for navigation with dynamic constraints [PDF]

open access: yesIEEE/RSJ International Conference on Intelligent Robots and System, 2003
We address the problem of applying reactive navigation methods for collision avoidance to systems where the dynamics cannot be neglected: mobile robots with slow dynamic capabilities, or systems working at high speeds. Rather than embedding the motion constraints when designing a navigation method, we propose to introduce the robot dynamic constraints ...

Dynamic Obstacle Avoidance for Unmanned Underwater Vehicles Based on an Improved Velocity Obstacle Method

open access: yesSensors, 2017
In view of a dynamic obstacle environment with motion uncertainty, we present a dynamic collision avoidance method based on the collision risk assessment and improved velocity obstacle method.

An autonomous dynamic collision avoidance control method for unmanned surface vehicle in unknown ocean environment

open access: yesInternational Journal of Advanced Robotic Systems, 2019
There are many unknown obstacles in the sea, so the autonomous navigation of unmanned surface vehicle needs to avoid them as soon as possible even under the condition of low control ability of the controller.

A Dynamic Localized Adjustable Force Field Method for Real-time Assistive Non-holonomic Mobile Robotics [PDF]

open access: yes, 2015
Providing an assistive navigation system that augments rather than usurps user control of a powered wheelchair represents a significant technical challenge.

Habitual Criminal Statutes: Shield or Sword [PDF]

open access: yes, 1954
An essential part of future collision avoidance systems is to be able to predict road curvature. This can be based on vision data, but the lateral movement of leading vehicles can also be used to support road geometry estimation.

Decentralized 3D Collision Avoidance for Multiple UAVs in Outdoor Environments [PDF]

open access: yes, 2018
The use of multiple aerial vehicles for autonomous missions is turning into commonplace. In many of these applications, the Unmanned Aerial Vehicles (UAVs) have to cooperate and navigate in a shared airspace, becoming 3D collision avoidance a relevant ...

Dynamic collision avoidance using local cooperative airplanes decisions [PDF]

open access: yesCEAS Aeronautical Journal, 2019
In the near future, air traffic control (ATC) will have to cope with a radical change in the structure of air transport [1]. Apart from the increase in traffic that will push the system to its limits, the insertion of new aerial vehicles such as drones into the airspace, with different flight performances, will increase its heterogeneity.
