Hello All,
Team 1511 has been working on a summer drivebase project to help improve our competitive edge in upcoming years. These pictures show the current progress of the project, which is mostly in CAD at the moment. I have added captions just to clarify what each view entails.
We are using VexPro 3-CIM Ballshifters as our gearboxes. There are two CIMs on each side along with a Banebots RS-775 in a CIM-ile gearbox. The four pneumatic cylinders on the corners cause the bellypan assembly to drop down and greatly increase the amount of frictional force needed to move the base.

Isometric view of the whole drivebase from the front right corner.

Right side assembly. The outer wheels are using dead axles, the output shaft and center wheel are using live hex axles. The nylon cams are for chain tensioning.

Shows the top of the transmissions, the breaker, and the cylinder mounting plate.

A view from the bottom, shows the cool belly-pan lattice and rivet holes.

The separate bellypan assembly, electronics included free of charge.
Thank you for any feedback on the design work, your insight is greatly appreciated.
Sincerely,
Elliot Dowd
