Communication in Schools of Submersible RobotsFelix Schill (Research School of Information Sciences and Engineering)DATE: 2006-05-12 TIME: 11:00:00 - 12:00:00 LOCATION: RSISE Seminar Room, ground floor, building 115, cnr. North and Daley Roads, ANU ABSTRACT: Effective communication mechanisms are a key requirement for schools of submersible robots and their meaningful deployment. Large schools of identical submersibles require a fully distributed communication system which scales well, and optimises for "many-to-many" communication (omnicast, a.k.a. gossiping). As an additional constraint, communication channels under water are typically very low bandwith and short range. This talk introduces possible electro-magnetic communication channels suitable for under water environments. Theoretical findings on the omnicast communication problem are presented, as well as the implementation of a distributed time division multiple access (TDMA) scheduling algorithm in simulation and in hardware. Experiments were carried out on digital longwave radio and optical link modules, developed here at ANU. The results of the experiments are used to revisit the initial assumptions on communication in multi-hop wireless networks.
Felix Schill studied computer science at the University of Karlsruhe (Diplom der Informatik, 2003), with additional courses in electrical engineering and microsystems. He commenced studies as a PhD student at The Australian National University in 2003, as a team member of the Autonomous Underwater Vehicles Group. Previous research includes the areas of mobile robotic platforms, humanoid robots and computer vision. His current research is on submarine robotics and swarm communication methods.
