The Micro Swarm Robots Outdoor Localization System And The Approach

With the continuous development of science and technology，Robot manufacturingtechniques constantly improving，Because of the micro swarm robots has the advantages ofsmall size，high intelligence and low cost. It has been widely used in all walks of life. Becauseof the robot has so many advantages，in recent years，Researchers on research in the swarmrobots are gradually deepened. But the positioning problem of swarm robots has not been ableto be effectively solved.Outdoor localization in the traditional swarm robots mainly depends on a single GPS.But the accuracy is low, and it’s easily affected by obstacles in the cities and complexcountryside environments, which makes it impossible to get accurate position. In this paper,based on the DGPS technology and RSSI wireless location technology, a combinedlocalization systems is presented. The AVR microcontroller and XBee communicationnetwork is employed in the control platform. Experiments and simulations demonstrate thatthe positioning accuracy is greatly improved, the blind spots are eliminated, and the moreexact location can also be obtained in the complex environment. Furthermore, it is low powerconsumption, low cost, and high stability.Overall system adopts the Arduino platform， positioning system using a combination ofmultiple algorithms for positioning, solute positioning use pseudorange difference GPS，Which is completely satisfied the requirements of system，the assistant positioning systembased on a weighted average and least squares estimate algorithm of the wireless sensornetwork (WSN),It has solved the specific problems in the practical application before，hasgreat value in reality.
