Pattern formation using multiple robots

Pattern formation is one of typical problems in the field of multi-robot cooperation. It can be applied to complex application scenarios such as region coverage and path exploration. Compare to traditional multi-robot coordination algorithm, the method based on swarm robots to solve the issue of pattern formation has better scalability and dynamic adaptability and robustness. In this demo, we propose a scalable algorithm using a modified gradient descent technique which allows a swarm of robots to form a letter, such as `A´. In this demo, we verify our algorithm through experimentation in a team of self-organized robots, in which communication with each other is through Zigbee network.
