Robot Communications System Based on Embedded Linux

Based on embedded Linux,this paper presents how to realize long-distance or short-distance double control mode of robot system. The communications system is made of terminal of embedded Linux system and robot system.By using the technology of GSM/GPPS expander board and Qt/Embedded software,through GPRS network and serial communication separately,it makes long-distance or short-distance control robot go ahead,go back and move the four axes machine-arm.
