The final project for ENGS 146: Computer Aided Mechanical Design was a diwheel, a pedal-powered vehicle with two wheels sharing a common axis.  Teams of four competed in challenges of maneuverability, stability, and speed.

Each team was provided with a finite amount of steel stock, two hoop wheels, and two bicycles from which to cannibalize parts.  My design contribution focused on the "anti-gerbilling" mechanisms in the front and rear, which allowed the driver to remain (more or less) upright.  I also served as the primary welder for my team.

A primary feature of our diwheel was adjustability.  We were able to shift gears, move the seat and pedals, and change the angle of the rear stabilizing member to allow for more or less layback.  We also included a differential for improved steering and spring loaded our rear "anti-gerbilling" member to reduce jolting when the rider rolled backwards.

My team finished third overall, and won the stability challenge.
