In response to the policy of developing smart education proposed in New Generation Artificial Intelligence Development Plan published by the state, the work aims to accelerate the popularization and development of STEM education in primary and secondary schools, search and analyze relevant domestic and foreign documents and explore the development status by focusing on the development goals of STEM education and teaching. Case analysis, usage scenarios, questionnaire analysis and other methods are applied to analyze the functional form characteristics of STEM education products, and summarize relevant user needs and data in the smart classroom. By extracting the needs of the smart classroom STEM course, a set of modular and emotional intelligent robot product “AMIGO” based on physical interaction is designed and developed. It is composed of more than ten kinds of sensors, electronic components and motherboards. It integrates multiplayer competitions and cooperation of online programming courses.
