    About Swarm Robots

    Swarm robots is a system consisting of large numbers of simple robots. Under the control of swarm intelligence principles, it is supposed that a desired collective behavior emerges from the interactions between the robots and interactions of robots with the environment. Mostly, these principles are inspired by insects or birds, which have swarm behaviors. Swarm robots also have the function of perception, memory and information processing. With these characteristics above, swarm robots can be able to complete some complex tasks.

    Research on Coordination Behavior of Swarm Robots Based on Stigmergy

    Stigmergy is kind of biological information coordination mechanism. Individuals in the swarm affect the behaviors of other individuals indirectly through leaving pheromones in the environment without central control and direct information communication. Finally, systematic activity characteristics are supposed to emerge in the swarm. Using stigmergy in the control of coordination behaviors, e.g., aggregation, foraging, of swarm robots helps to avoid the disadvantages of central control and "information explosion" of direct communication when population size is large.

    Swarm Robots Search for Multiple Targets Simultaneously Guided by Particle Swarm Optimization

    Particle Swarm Optimization regards the space where particles move as the solution space of the problem to be solved. Particles communicate with each other and continuously approach the best solution. When utilizing swarm robots to search for multiple targets simultaneously, we can regard every robot as a particle, group these robots dynamically and use Particle Swarm Optimization to guide every group to search for the target nearby. Finally, the swarm of robots are able to find multiple targets in the environment.

    Development of Swarm Mobile Robots

    A kind of small omni-directional mobile robot and a experimental platform of swarm robots are developed by our lab. The small mobile robot has functions of omnidirectional moving, light strenght sensing, obstacle avoidance using infrared sensors, reading and writing RFID tag, wireless communicating using Wi-Fi module and so on. The experimental platform consisting of many this kind of robots is utilized to study, realize and validate various swarm intelligence algorithms.
