SuperMan Wheel Fix By Jose

Task: 3D model a fix for Superman using Fusion 360

During the Discovery Faire Icarus' Superman wheel broke as the gears were skipping, rendering most robot articulations useless. For reference, Icarus was our robot for the 2019 World Championship and the Superman wheel is a mechanum wheel fixed to the base of the robot that, when extended, allows the robot to stand upright to a height of approximately 5 feet. The problem was the top gears were separating from each other and that caused them to also separate from the SuperMan gear. There is an easy fix for this, use a bar to join the motors together, effectively doing the same to the gears.

This part was modeled by measuring the distance between the motors and the holes of the gearbox to hold the bar down. This ended in a bar 163.5mm long with holes spaced accordingly. This was simply extruded and the edges were made round. After the bar was printed it was proven to be tool long, the issue being the space between the motors is 62mm not 102.5mm.

Next Steps

We need to test the part on the Superman Wheel to see if its able to perform its articulations functionally.
