Based on TPRAI educational objectives, this study developed a TPRAI educational robot system, which can interact with children learners in a multimodal manner through remote control, image recognition, and voice dialogue. In this study, we adopt MIAT methodology to design the TPRAI educational robot system. We decompose the complex robot system functions into four subsystem modules, such as audio and video detection, WIFI communication, audio and video recognition, and robot control, and conduct discrete event modeling and high-level software synthesis for each subsystem. Based on open source hardware and low-cost peripheral components, the TPRAI educational robot can interact with learners in a friendly multimodal manner through image recognition and voice recognition, and can provide further development of early childhood information education applications such as computational thinking, programming, and AI in the future.
