Swarm robotics is inspired by insects and their colony and is applied to solve real- world problems utilizing autonomous agents. Research in the field of swarm robotics has revealed the competency of such robot systems to assemble, inspect, disperse, aggregate and follow trails. Swarm robots are autonomous, self-sufficient, oblivious, memoryless robots and have very restricted capabilities .These can form simple patterns in the environment they inhabit. These simple patterns can be used by the robots to achieve some real-time or high-level tasks. In this paper, the focus is on finding the algorithm of circle formation of swarm robots. Relevant circle formation methods are reviewed and compared. The objective of this review is to provide an overview about circle formation using swarm robots, limitations and considerations on dealing with the swarm of robots.
