Summary

Introduction

Mobile robots have become a more fundamental part of the industry. In general, obstacle avoidance has turned out to be pre-requisite to mobile robots and this has resulted in the introduction of a large variety of algorithms to support obstacle avoidance. The leadership exchange is the backbone of the leader-follower system [6], [7] This was utilized in the present work to design an efficient multi robot obstacle avoidance strategy. This new strategy assumes that the robots in the system possess only basic sensing and movement capabilities allowing other robots to take over and complete the task in case of breakdown of the leader robot. The concept of information exchange across multiple robots [8], [9] was implemented to achieve better path navigation This new strategy is a modified BUG-1 strategy which is implemented across multiple robots for improving travel time and energy expenditure of robots and providing a better success probability of task at hand.
