The Internet of Things (IoT) in the education sector has provided new learning opportunities. This paper discusses an IoT-based Assistant Teacher Robot that assists teachers in monitoring activities, such as student attendance, delivering instructions, and communicating with students. The robot is constructed using an ESP32 microcontroller with components such as an LCD, ultrasonic sensor, camera, Wi-Fi and Bluetooth modules, DC motors, an RFID module, and an L298N motor driver. The robot utilizes IoT connectivity to access online learning materials, respond to students' queries, and provide real-time feedback. The camera and sensors enable navigation, obstacle detection, and classroom monitoring while enabling smooth Teacher and student interaction. Remote updating and control are facilitated by wireless communication. This assistant robot minimizes the teacher’s workload, and students become more active. This Assistant Teacher Robot facilitates an interactive and productive learning process. The system exhibits the potential of IoT and robotics in the contemporary education sector, facilitating intelligent classrooms.
