%A Van Nam Tran %A Anh Quy Hoang %A Minh Trien Pham %T Design and Implementation of a Multi-Robot System Based on Zigbee Network %X Multi-robot system is widely used for collecting environmental data, patrolling in factories or boundaries, searching and rescuing. In this paper, a multi-robot system (MRS) was designed and implemented. The robots in this system communicate over a Zigbee network. This MRS is capable of avoiding collision; detecting light sources; getting information on temperature and humidity in its work space, as well as the position of each robot using GPS antennas. The collected data are sent to and stored in a server for further analysing and predicting environment condition. The MRS could be used in monitoring factories. A prototype system consisting of three mobile robots was developed and it has successfully detected light source in laboratory condition. %C Hanoi, Vietnam %D 2016 %L SisLab2277
