"Mars Rover"
From September 2015 to April 2016 I was part of the University of Toronto's Robotics for Space Exploration (RSX) design team. The team was constructing a rover for the 2016 University Rover Challenge, which was a competition in a simulated Martian terrain in Utah. My role on the team was to design the wheels and part of the suspension system for the rover, with the primary objective of minimizing weight. I designed the wheels as hard polyurethane rubber tires molded onto drums that would be fastened to motor shafts with custom made hubcaps. This gave the wheels a large surface are with a deformable surface to damp vibrations while traveling over rough terrain, while keeping the wheels light. While designing the components I created 3D CAD models in SolidWorks, which I then imported into ANSYS for stress analyses under different loading conditions. This allowed me to trim unnecessary material in order to reduce weight, resulting in wheels that were 40% lighter than the previous year's rover.
