Abstract:The robot techniques development is making over in an astonished velocity. Today ,all kinds of robots have different shape and function appear in everywhere. The robot that used the turning theory of human being and the motion theory of cankerworm is introduced. Micro-robot is an important offset of robot technique. This paper has solved three problems of this kind of micro-robot. One is the mechanical structure design, and the second is controlling circuit design, the third is measurement system design. Two new pattern micro-robots have been made which not only can move on the smooth armor plate, but also can turn its body quickly and freely. This new pattern micro-robot has strongly driving power, which also can be refitted another walking-type robot. At the same time, it also succeeded in controlling the robot through the microprocessor AT89C52 and the other new type controlling circuit. Taking the chip of LG9110 as the positive and negative driver, and the chip of SN75451B as the driver of the other parts, not only the design of circuits become easily, but also circuit board become simply. It provides some diagrams of program. In short, through the experiment, it gains some important data of making this kind of robot on the other hand, the experiment proves that the project not only can control the robot freely, but also offers a new idea for the studying of this kind of micro-robot.
