Collision Avoidance Algorithm of Mobile Robots at Grid Map Intersection Point

Cooperative collision avoidance between multiple mobile robots

This paper presents a new collision avoidance technique, called cooperative collision avoidance, for multiple mobile robots. The detection of the danger of collision between two mobile robots is discussed with respect to the geometric aspects of their paths as are cooperative collision avoidance behaviors. The direction control command and the velocity control command for the cooperative collis...

Development of Intersection Collision Avoidance Algorithm for B2V Safety Service

In this paper, we proposed the intersection collision avoidance (ICA) algorithm for bicycle to vehicle (B2V) safety service and analyzed its performance by using ‘PreScan’ and ‘MATLAB’. As typical type accidents related with bicycles, we consider the bicycle to vehicle (B2V) communication. The derived analytical approach can explain the condition and effect of bicycle collisions. Furthermore, p...

Collision and Turnover Avoidance of Mobile Robots with Force Reflection

Collision and turnover are fatal to mobile robots. Control methods are suggested for solving the fatal problems of mobile robots maneuvered by an operator. Speed reduction and wall following are applied for collision avoidance using ultrasonic sensor data. Modified Hough transform is suggested to obtain a wall model from sonar data overcoming limitations of ultrasonic sensors. The robot is also...

Survey of collision avoidance and ranging sensors for mobile robots

A Hybrid Collision Avoidance Method for Mobile Robots

This paper proposes a hybrid approach to the problem of collision avoidance for indoor mobile robots. The DWA (short for: model-based dynamic window approach) integrates sensor data from various sensors with information extracted from a map of the environment, to generate collision-free motion. A novel integration rule ensures that with high likelihood, the robot avoids collisions with obstacle...
