A Collision Avoidance Method for Intelligent Ship Based on the Improved Bacterial Foraging Optimization Algorithm

open access: yesJournal of Robotics, 2021
The bacterial foraging optimization algorithm (BFOA) is an intelligent population optimization algorithm widely used in collision avoidance problems; however, the BFOA is inappropriate for the intelligent ship collision avoidance planning with high ...

Continuous-Time Collision Avoidance for Trajectory Optimization in Dynamic Environments [PDF]

open access: yes2019 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2019
Common formulations to consider collision avoidance in trajectory optimization often use either preprocessed environments or only check and penalize collisions at discrete time steps. However, when only checking at discrete states, this requires either large margins that prevent manipulation close to obstacles or dense time discretization increasing ...

Exploration, Path Planning with Obstacle and Collision Avoidance in a Dynamic Environment

open access: yesCoRR, 2022
If we give a robot the task of moving an object from its current position to another location in an unknown environment, the robot must explore the map, identify all types of obstacles, and then determine the best route to complete the task. We proposed a mathematical model to find an optimal path planning that avoids collisions with all static and ...

Collision avoidance for multiple Lagrangian dynamical systems with gyroscopic forces [PDF]

open access: yesInternational Journal of Advanced Robotic Systems, 2017
This article introduces a novel methodology for dealing with collision avoidance for groups of mobile robots. In particular, full dynamics are considered, since each robot is modeled as a Lagrangian dynamical system moving in a three-dimensional environment. Gyroscopic forces are utilized for defining the collision avoidance control strategy: This kind
