Smart Delivery Bot: An Autonomous Indoor Delivery System Using Embedded Technology

The increasing demand for efficient, contactless deliveries in indoor environments has highlighted the challenges in last-mile logistics, particularly in cost, scalability, and operational efficiency. To tackle these challenges, we have developed the Smart Delivery Bot (SDB)—an autonomous robot designed to seamlessly transport items within indoor spaces such as offices, hospitals, and restaurants. The SDB is powered by an Arduino Uno microcontroller, which serves as the central processing unit, coordinating various sensors and actuators to ensure smooth navigation and obstacle avoidance. Additionally, the bot is equipped with a camera that provides a live video feed to monitor its surroundings in real-time. This smart system decreases human involvement, speeds up workflows, and boosts productivity by simplifying the transport of goods indoors. The system uses Bluetooth for communication, detects obstacles in real-time, and streams live video to ensure deliveries are accurate, quick, and safe. The bot uses infrared (IR) sensors for following paths, ultrasonic sensors for avoiding obstacles, and an ESP32-CAM module for constant real-time monitoring.
