Research On The Design And Application Of Assisted Teaching Robot Based On Constructivism

With the development of artificial intelligence technology and robot technology,the robot will have wide coverage of knowledge and highly intelligent level.It provides a possibility that will bring disruptive change in the field of education and achieve the personalized teaching and teaching students according to their aptitude.The research of robot assisted teaching is still in the initial stage in the research direction of educational robot.Some research institutions at home and abroad have carried out relevant research.Robot technology is a means of teaching,and "auxiliary teaching robot" as one of the main tools to implement robot assisted teaching,is only a conceptual product.The application of robot in the teaching process will change the traditional way of teaching and learning,and it will also promote the transformation of teachers' work.In this paper,the robot assisted teaching as the research object,carries out research from the perspective of theory and practice,exploring the ideas and schemes of robot applied in classroom teaching practice,in order to bring a breakthrough and development for the field of robot assisted teaching.The main research work of this paper is as follows:1.Aiming at the problem of lack of teaching idea in robot aided teaching,this paper puts forward a constructive teaching model based on constructivism and the constructive teaching design and the function of robot.The set of variables in the teaching design system is constructed by means of the system dynamics model,and the quantitative model of the teaching design pattern is established by using the structural equation model modeling method.2.This paper analyzes the key elements of robot assisted teaching system and their relations,the establishment of C-RAI in the design of "learning oriented teaching" and "learning" the two part detailed exploration,combined with the robot technology and multimedia technology,putting forward teaching mode and online answering mode of classroom robot.3.Based on the comprehensive analysis of the functional requirements of the robot in RAI teaching,a teaching assistant robot for RAI is designed.The humanoid structuredesign of "robot torso + fixed base" is designed,and the robot control system is adopted to realize the robot Mechanical movement and voice synthesis and other basic teaching functions.And use ROS MoveIt to build the robot movement planning platform,the robot movement simulation and simulation.4.The software design of the control system is divided into three parts: the software design of the host computer,the software design of the lower computer and the design of the speech synthesis system.ROS MoveIt is used to build the movement planning platform of the helper robot,and the robot movement is simulated.5.According to the basic framework of C-RAI teaching design pattern,we will complete the detailed teaching case design,and use the assistant robot as the auxiliary teaching tool,apply it to C-RAI teaching case and implement RAI teaching practice.This paper analyzes the teaching results by means of comparative analysis and investigation and analysis.It is proved that the new teaching form of RAI is feasible and the way of learner-centered,teacher-oriented and robot-oriented new teaching and learning is realized.
