Bluetooth RSSI based collision avoidance in multirobot environment

Abstract

Multi-robot system is gaining its importance in robotic research. One critical issue in multi-robot system is collision among the mobile robots while sharing same workspace. This paper deals with the collision-free path planning for multiple mobile robots using Bluetooth RSSI value. In the proposed collision avoidance algorithm a decentralized approach with fixed priority level for robots is considered. A variable speed technique based on the RSSI value of robots is used and the obstacle avoidance is implemented based on State based Obstacle Avoidance Algorithm. Proposed algorithm is implemented and tested using Webots 3D simulator.
