We were tasked to research, design and assemble a purely mechanical AGV as a group. It had to transport an item forward, stop, release it and return to its original position. As the team leader in I divided the tasks between the five team members, and constrained by both materials and a budget a low-cost, smooth and efficient prototype was developed. When designing the release mechanism I 3D printed and tested prototypes to find its flaws, increase my CAD skills and experiment with 3D printing.
