Abstract/Summary
Our project is the third iteration of a design to create a small Mars rover. Our main challenge was to change the existing rover structure into something that could survive the harsh conditions of Mars. This meant altering the design so that it could resist the large temperature fluctuations while still maintaining the structural stability and interface to support driving functions and the projects of the other rover teams. Our team accomplished this goal by altering the design of the existing rocker bogey from completely 3D printed to a tube and joint system. The longer portions of the rocker bogey system were changed to square carbon fiber tubing connected by 3D printed attachment points. This allowed us to use a stronger, space grade material From Carbon 3D called CE 221 for all the joints. Through our testing, we were able to conclude that the design chosen will be able to easily withstand the expected loading conditions. However, due to outsourcing issues, we were unable to complete the temperature testing; but have included plans for testing once the parts arrive.
