The main objective of this research is to study a teaching robot with humanized control interface and interactive teaching method with children. The program, circuit, and mechanism will be studied and an interactive teaching robot will be designed based on object recognition and servo motor, with a tablet computer as a point-and-click interaction. The hardware architecture of this study is divided into: 1. main controller (Jetson AGX Xavier), 2. interactive interface (Android device), 3. power supply system, and 4. motor unit. The robot has five degrees of mobility of the arms; the head is a tablet computer as the English teaching control interface. The main controller is Jetson AGX Xavier Developer Kit, and the program is mainly in Python language, and is transmitted through Android and Bluetooth. The robot also incorporates a recognition system to increase interactivity. The robot will play the role of a teacher's assistant in the classroom, and the target group will be a small group of students. The content is mainly based on word teaching and highly interactive and fun English games, and the purpose of supplementing learning is to enhance children's interest in learning through the tablet interface control and recognition interaction system.
