Title The Construction and Control Algorithm Research of Lego Robot with NXT Controller

Abstract Robot is a frontier research field of photoelectric signal and the integration of computer control with high technical and difficulty, is one of the important symbol of the levels of high-tech research and development。 Robot can be realized in severe danger environment maintenance, rescue, detection, etc。, can also play an important role in service, entertainment industry。 Robot has a broad application prospect。 So the overall design, control algorithm of robot research and the simulation experiment are very important in scientific research。 This paper uses 9797 lego education suit and 45560 supplementary package, based on the NXT controller, servo motor and the multi-sensor information fusion, builds model independently by selecting appropriate control algorithm to complete the specific tasks (such as obstacle avoidance, patrol, automatic approach) and realize the control purpose。 This article mainly includes the following aspects:

(1)The building of Lego robot according to the needs of social development at this stage, through the analysis of the characteristics of each sensor, selecting the appropriate sensors to install, building the robot's body structure;

(2)The ues of Lego programming software, combined with the control requirements, the use of suitable control algorithm, to achieve obstacle avoidance, patrol line, automatic approach , etc。;

(3)Learning the use of the fuzzy PID algorithm, and the theoretical research of fuzzy PID algorithm, and the research of the possibility of its application。 Using matlab/simulink to simulate the control algorithm , selecting the appropriate control parameters combined with the simulation results and the actual working environment, adjusting the control parameters。
