Design And Optimization Of Graphical Programming Module For Educational Robot

Graphical programming means that functional code is encapsulated into a module,and the programmer can complete the logical design only by generating,assembling,and linking modules.Graphical programming has the characteristics of low threshold and simple operation,and has broad application prospects.Based on the existing problems of the educational robot graphical programming software in module development and module layout,this paper focuses on the design of the graphical programming module of the educational robot,the design of the module operation and the layout optimization of the module.The main work is as follows1)Modeling and design of graphical programming module for educational robot: By studying the appearance and function of modules,a model of four element model and element combination is proposed.The four element module model is used to organize the module information,and the element composition model is used for the construction and implementation of the module class.Among them,the four yuan module model can describe the organizational structure of modular information,which is convenient for the expansion of modules.2)The definition and design of educational robot graphical programming module operation: By studying module operation,the module operations are formally defined based on predicate logic.The module operations definition includes all the details from user input to software processing.Through the definition and design of module operation,it is easy to manage and track all module operations.3)Education robot graphical programming module layout optimization: Based on the shortage of the existing educational robot programming software on the display,this paper presents a module arrangement and connection algorithm of obstacle avoidance algorithm management module and the module of all relations,which do not overlap between modules,connection is not covered on the display module,module layout optimization.
