Design Of Intelligent Mobile Robot Based On NI MyRIO

With the rapid development of information technology,such as mobile Internet,cloud computing and Internet of things,the new generation of information technology such as big data and Internet of things has been integrated into industrial production.Modern industrial production and social services have put forward intelligent and networked requirements for mobile robots.Research on mobile robot based on multi-sensor information fusion,navigation and path planning technology,design,intelligent mobile robot platform based on NI control system design of myRIO and the design of color recognition algorithm based on the analysis,the omnidirectional mobile Mecanum wheel,and complete the verification and analysis of the function of the mobile robot in the experiment site.The main contents of this paper can be summed up in the following aspects:Analysis of mobile robot multi sensor information fusion technology,navigation and path planning technology;complete design and selection of mobile robot body structure,driving system,sensor system;3D modeling of mobile robot,the parts between the interference check.Analysis of Mecanum wheel and the installation form;to establish the mathematical model of double measuring wheel steering and mobile robot,analysis of the relationship between the two measuring wheel speed,angle and four Mecanum wheel speed and vehicle speed and vehicle omnidirectional geometric center angle theoretically;considering kinematic equations of slip factor,the omnidirectional driving direction,different car the driving distance in the specified displacement deviation of horizontal and vertical,and ultimately determine the Mecanum wheel,radial slip rate.The mobile robot control requirements,formulate control system hardware design scheme of the intelligent mobile robot NI based on myRIO;design of the mobile robot,omnidirectional mobile pose adjustment,lifting and clamping mechanism of the structure of the program,complete the preparation of the experimental procedure;analysis of color recognition algorithm,designed the color recognition module of mobile robot.Complete the assembly and debugging of intelligent mobile robot system NI based on myRIO,with the help of a world-class mobile robot competition venues to contest the functional verification and testing of mobile robot system.The experimental results show that the mobile robot can complete the omnidirectional mobile billiards crawl,positioning and posture adjustment,color recognition functions according to the predetermined target,experimental error exists in the testing process,but the errors are within a reasonable range,to verify the rationality of the design of mobile robot.
