This study presents the design, development, and testing of an innovative 3D printed warehouse elevator prototype controlled by Arduino Uno. The prototype addresses efficiency challenges in modern warehouse operations by automating vertical transport systems. Utilizing accessible manufacturing techniques, the elevator mechanism combines custom 3D printed components with standard hardware to create a cost-effective solution scalable for various warehouse configurations. The Arduino Uno microcontroller serves as the central control unit, managing motor functions, floor detection, and operational sequences through custom programming. Testing demonstrates the prototype's ability to carry scaled loads between multiple levels with precise positioning accuracy and consistent performance metrics. Power consumption analysis indicates significant energy efficiency compared to conventional hydraulic systems, while the modular design allows for rapid assembly and maintenance. This project contributes to the growing field of smart warehouse management by providing an open-source foundation that can be adapted across different industrial applications.
