At the same time, considering the jumpiness or incline caused inaccuracy and pretermission when the capsule moving ahead, two couples of infrared ray and electron transducer were designed to detect the light signal of the corresponding parts of the capsule. After the addition operation compensation and differential coefficient, turning the little different simulation signals of the body and cap of the capsule into digital signals for detection. It is more accurate for detection and stable to the disturbance. Step electromotor was used for the capsules direction turning which solved this problem efficiently. The capsules were ranged in order according to their colors with the cap at the same direction.
