Currently, there is a lack of an in-home automatic lifting mechanism in the hand truck industry that is low in weight and cost. This project aimed to create an original design of an automatic hand truck, suitable for in-home use, particularly assisting the elderly or injured individuals with heavy lifting. The steps taken to achieve this goal included, calculating values necessary for proper operation of the product, creating a CAD model of the design, manufacturing a scaled prototype of the design, testing the prototype, and proposing recommendations for full scale manufacturing. At the conclusion of the project, qualitative testing demonstrated that the ball screw assembly used within the hand truck operated successfully, providing a proof of concept.
