All kinds of intelligent car market in the toy also accounted for a large proportion. The hightech content of electronic interactive toys has bee the mainstream of the toy industry development. Therefore, remote control and intelligent technology research, application are useful and have high market value. Paper outlines based infrared detection of the road obstacles, and use a AT91SAM7S64 singlechip as the controlling core for the speed and direction of CDS5500, A electronic drived, which can avoid the obstacle, was designed and fabricated. The main contents include AT91SAM7S64 microcontroller, infrared sensors also CDS5500 motor works, as well as a description of each part of the circuit. Software module introduces several important debugging process.
