The research describes how to build an autonomous delivery system which operates in educational environments with their structured and predictable environments. The system operates through two navigation systems which allow users to control it manually using Bluetooth and enable the vehicle to follow lines for turning within school environments. The system depends on basic ultrasonic sensors which work with servo-controlled scanning to detect obstacles automatically. The ESP32-CAM module allows video streaming which enables the vehicle mission supervisor to monitor operational time for maintaining continuous safety. The system design follows Internet of Things (IoT) principles through embedded controllers (Arduino UNO and ESP32-CAM) which enable sensor integration and mobile app development using MIT AppInventor. The system consists of easy-to-maintain and affordable hardware and software components which operate as separate modules. The system enables unrestricted movement through standard Vietnamese school buildings. The system operates reliably at Uông Bí secondary school (Quảng Ninh, Vietnam) during testing experiments which demonstrate its ability to detect obstacles and change operation modes on the concourse. The solution demonstrates excellent potential for educational logistics and internal document delivery and STEM and hands-on STEM and IoT education programs
