Summary

As a member of SJSU Robotics' Mechanical Design Engineering team, I worked on the design and manufacturing of the Chassis & Suspension for the rover ("Nessie"). I also developed CADs of sheet metal parts to be used for the Chassis as well as acrylic pegboards (that are integrated onto the Chassis) while minding adherence to mechanical specifications. The acrylic pegboards were used to hold the electrical components.

Project Nessie was SJSU's competitive rover for the 2016 University Rover Challenge, an international collegiate challenge where universities competed in Hanksville, Utah, to see who designed the most "Mars-ready" rover!
