Its basic principle is to monitor the arc light automatically by the photosensors; the photoelectric signal is analysed and processed automatically by the microprocessor, then it drives the liquid crystal light valve to turn from a "clear state" into a "dark" protective state rapidly . Meanwhile , when the arc light disappears, the system makes the liquid crystal light valve resumed the bright attitude by auto-delay,and microprocessor adjusts eye protection circuit intelligently to reduce the consumption in the maximal degree, which make the working time achieved one or two years by ordinary button cell cooperates with photocells .

In this paper RoboCup Mid-size Robot are the object of study from the two sides of the robot system and the system of multi-robot cooperation, the main research results are as follows: First, this paper reasearches the problom of the hardware and software architecture of Mid-size robots. According to the real-time requirements of the competition, the paper designs the mechanism of omni-direction wheels, which achieves a great improvement on the traditional mechanism of two wheels robot, and a more flexible response. This mechanism can adapt well to the increasingly rapid pace of the competition. In allusion to the mechanism of omni-direction wheels, this paper designs the electrical control system of three nodes in the bottom, which could communicate fast to the laptop with serial port and match the real-time requirements well. According to the problom of hitting power and speed of robot when shooting, this paper designes a motor-driven tongue-shaped spring shooting mechanism, which has a simple mechanical structure, smaller space in size and simple control circuit. This shooting mechanism meets the real-time requirements of the competition better.

Two GFRF system model identify algorithms based respectively on Signal Flow Graph/Driving Point Impedance and EDA simulation are proposed. In order to solve the problem of fault diagnosis that the inner structure and parameters of the Object under Test cannot be able to determine, a new fault diagnosis method based on the phase space reconstruction and GFRF general formula is investigated. This method builds up a bridge between the chaos theory and Volterra series analysis, which does not strongly depend on the topological structure and the testing data length, is sensitive to the fault property, traces monotonously the change of system fault, and possesses some significant predominance compared with conventional fault diagnosis methods of analog circuits.
