By using infrared sensor to locate the
3、 trace、photoelectricity sense to measure the light、 metal sensor to detect the metal and ultrasonic wave sensor to avoid the barrier. Based on the reliable hardware and software designing,this design is well fulfilled. In addition, such extended functions as measuring thedistance and recording the r
4、unning-time are completed well. On the level of machine structure, we use a perfect wheel to make the car turning more convenience.
