Abstract

Our project regarded making a design for a cart that is able to move items up a flight of stairs in an efficient manner. This project was meant to resolve was the lack of a cart currently on the market that could be used by moving companies in order to perform jobs involving heavier loads, as well as avoiding injuries such as chronic joint pain. In order to test the designs generated, a contruction of the cart on a smaller scale using VEX parts, was utlized to try different tread designs as well as test a breaking system. To test the micro scaled cart, a smaller wooden mockup of a stair case was created using quarter-inch thick plywood, and featured 8 steps. The smaller wooden steps and the smaller cart allowed to a simulation of the cart on a larger scale. The test were done in trials where force to move up the flight of steps and weight held while breaking was calculated in orde rto determine the best design. The simulation on a smaller scaled allowed for the safety risk to be mitigated, that otherwise would have been present in a full scale model. After the test, the design feature triangle pieces for the treads was chosen as it showed the most positive results. Once chosen the cart was then built at a full scale and tested on an actual stairs case. Furthermore any noticeable flaws in the design on the full scale model were adjusted.
