Cloud based Real time Multi robot Collision Avoidance for Swarm Robotics
Nowadays, Cloud Computing has brought many new and efficient approaches for computation intensive application areas. One typical area is Cloud based real time device control system, such as the IoT Cloud Platform. This kind of platform shifts computation load from devices to the Cloud and provides powerful processing capabilities to a simple device. In Swarm robotics, robots are supposed to be small, energy efficient and low cost, but still smart enough to carry out individual and swarm intelligence. These two goals are normally contradictory to each other. Besides, in real world robot control, real time on line data processing is required, but most of the current Cloud Robotic Systems are focusing on off line batch processing. However, Cloud based real time device control system may provide a way that leads this research area out of its dilemma. This paper explores the availability of Cloud based real time control of massive complex robots by implementing a relatively complicated but better performed local collision avoidance algorithm. The Cloud based application and corresponding Cloud driver, which connects the robot and the Cloud, are developed and deployed in Cloud environment. Simulation tests are carried out and the results show that, when the number of robots increases, by simply scaling computation resources for the application, the algorithm can still maintain the preset control frequency. Such characteristics verify that the Cloud Computing environment is a new platform for studying massive complex robots in swarm robotics.
