With the increasing level of automation in industry and agriculture, the demand for material transport vehicles becomes higher and higher. In order to solve these shortcomings of the accuracy, speed and stability of the material transport mini vehicle, some better design methods are proposed for it. A photoelectric tracking transport mini vehicle was developed using two methods. One is that the chassis structure contains the universal wheel and the tire, and the other is that the motion path contains two parts: backward and forward. The vehicles developed in this paper have greatly improved the above-mentioned deficiencies and good practical effects. Further, the proposed methods can also be slightly supplemented and applied to larger vehicles in addition to the miniature ones.
