In recent years, automation in logistics and material handling has gained significant momentum, particularly with the rise of smart infrastructure and Industry 4.0. This paper presents the design and implementation of an Autonomous Delivery Robot that leverages a compact and efficient control system based on the Raspberry Pi Zero. The robot is engineered to perform end-to-end delivery tasks without human intervention--picking up material from a designated source and transporting it to a specific destination where it autonomously dumps the payload. The robot incorporates a GPS module for real-time geolocation tracking, a camera module for visual feedback and object detection, and ultrasonic sensors for collision avoidance, enabling reliable navigation and obstacle avoidance. The Raspberry Pi Zero processes data from these modules and coordinates movement using dual motor driver circuits--one for robotic mobility and another for controlling the headlamp or dumping mechanism. Furthermore, the system incorporates IoT-based communication, allowing external devices or users to assign delivery tasks, monitor robot status, and receive real-time updates. The proposed robot system is scalable and cost-effective, suitable for indoor and outdoor applications such as warehouse automation, hospital supply delivery, or campus logistics. This project demonstrates the viability of autonomous material transport using low-power embedded systems and lays the foundation for future enhancements involving AI-based path planning and autonomous fleet coordination.
