Current wireless robot system is usually composed by a micro controller system, bare micro controller constrained by hardware characteristics, it is difficult to satisfy many complex control while ensuring system real-time. View of this, the article based ARM9-structured processor and embedded Linux system, optimized and improvement the versatility and real-time capacity of wireless remote control car. The robot system collected the data by sensors and transmits the data to the PC console which designed as the main calculate and determine center in the system by WIFI. PC sent the final commends to robot and the robot executes them. Through a simple hand signal recognition test, with several times experiments, as a consequence, has proven the wireless remote control car system might accomplish the complex multi-task controls under the safeguard timely premise. So long as in the WIFI hot spot coverage area, the infinite distant place server can apply current intelligent algorithms in the real life rely on the wireless remote control car system.
