The dynamic window approach to collision avoidance [PDF]

open access: yesIEEE Robotics & Automation Magazine, 1997
This approach, designed for mobile robots equipped with synchro-drives, is derived directly from the motion dynamics of the robot. In experiments, the dynamic window approach safely controlled the mobile robot RHINO at speeds of up to 95 cm/sec, in populated and dynamic environments.

Obstacle avoidance in a dynamic environment: a collision cone approach [PDF]

open access: yesIEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 1998
A novel collision cone approach is proposed as an aid to collision detection and avoidance between irregularly shaped moving objects with unknown trajectories. It is shown that the collision cone can be effectively used to determine whether collision between a robot and an obstacle (both moving in a dynamic environment) is imminent. No restrictions are

Chance-Constrained Collision Avoidance for MAVs in Dynamic Environments

open access: yesIEEE 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.

Trajectory Tracking and Collision Avoidance Switching Control for Multi-UAV Based on DMPC [PDF]

open access: yesHangkong bingqi, 2023
Multi-unmanned aerial vehicle (UAV) system often encounters sudden static or dynamic obstacle threats during flight. How to realize obstacle avoidance is one of the key problems that must be solved for multi-UAV system.

Multi-ship Coordinated Collision Avoidance Decision Based on Improved Twin Delayed Deep Deterministic Policy Gradient [PDF]

open access: yesJisuanji kexue, 2023
At present,most models of collision avoidance algorithms take ships as single agent to make collision avoidance decisions,without considering the coordinated avoidance between ships.In the scenario of multi-ship meeting,it will lead to poor avoidance ...

Path Planning of an Unmanned Surface Vessel Based on the Improved A-Star and Dynamic Window Method

open access: yesJournal of Marine Science and Engineering, 2023
In order to ensure the safe navigation of USVs (unmanned surface vessels) and real-time collision avoidance, this study conducts global and local path planning for USVs in a variable dynamic environment, while local path planning is proposed under the ...

Dynamic Vibrotactile Signals for Forward Collision Avoidance Warning Systems [PDF]

open access: yesHuman Factors: The Journal of the Human Factors and Ergonomics Society, 2014
Objective: Four experiments were conducted in order to assess the effectiveness of dynamic vibrotactile collision-warning signals in potentially enhancing safe driving. Background: Auditory neuroscience research has demonstrated that auditory signals that move toward a person are more salient than those that move away. If this looming effect were found

Verifying collision avoidance behaviours for unmanned surface vehicles using probabilistic model checking [PDF]

open access: yes, 2016
Collision avoidance is an essential safety requirement for unmanned surface vehicles (USVs). Normally, its practical verification is non-trivial, due to the stochastic behaviours of both the USVs and the intruders.
