[Abstract]:With the development of artificial intelligence technology and robot technology, robots will have a wide range of knowledge coverage and highly intelligent level. It provides a possibility for individualized teaching and teaching students according to their aptitude, and will certainly bring subversive changes to the field of education. In the research direction of educational robot, the research of robot assisted instruction is still in its infancy, and some research institutions at home and abroad have carried out related research. Robot technology is the means of auxiliary teaching, and "auxiliary teaching robot", as one of the main tools to implement robot auxiliary teaching, is only a conceptual product at present. The application of robot in teaching process will change the traditional way of classroom teaching and learning, and will also promote the transformation of teachers' work. In this paper, robot assisted instruction is taken as the research object, which is studied from the point of view of theory and practice, and the ideas and schemes of robot application in classroom teaching practice are explored in order to bring breakthrough and development to the field of robot assisted instruction. The main research work of this paper is as follows: 1. In order to solve the problem of lack of teaching idea guidance in robot assisted instruction at present, a robot aided instruction design mode based on constructivism is proposed on the basis of constructivism teaching design and combined with the functional characteristics of robot. With the help of the idea of system dynamics model, the variable set of teaching design system is constructed, and the quantitative model of teaching design pattern is established by using structural equation model modeling method. 2. This paper analyzes the core elements of robot aided instruction system and their relationship, refines the two parts of C-RAI teaching design: "establishing learning orientation point" and "inquiry learning". Combined with robot technology and multimedia technology, the robot classroom teaching mode and robot online question answering mode are put forward respectively. Based on the comprehensive analysis of the functional requirements of robots in RAI teaching, an auxiliary teaching robot suitable for RAI is designed. The humanoid structure design of "fixed base of robot torso" is adopted, and the hierarchical control idea is adopted to construct the robot control system to realize the basic teaching functions such as robot mechanical motion and speech synthesis. ROS MoveIt is used to build the robot motion planning platform, and the robot motion is simulated and simulated. 4. According to the basic framework of C-RAI teaching design mode, the detailed teaching case design is completed. The auxiliary teaching robot is used as the auxiliary teaching tool, which is applied to the C-RAI teaching case and the RAI teaching practice is carried out. By means of comparative analysis and investigation and analysis, the teaching results are analyzed. The practice proves that RAI, a new teaching form, is feasible and realizes a new way of teaching and learning, which is learner-centered, teacher-led and robot-guided.
