Since we cut the prototype last week, I've been hard at work improving the design. We'll be fabricating this iteration tomorrow.


Full size here!

Some information and a partial change log:

-Weighs 36.7 lbs with everything shown except bumpers and battery
-Contains 34 plywood parts, which weigh a total of 15.9 lbs
-Gearbox removable from top or bottom with 4 bolts. Drive pod removable from side with 5 bolts
-Improved gearbox with stronger design, easier mounting, more choice in ratios and a slightly increased top speed of ~12fps adjusted
-Modified encoder mount for 3D printing
-Revised powertrain to use wheels and pulleys from AM14U so we don't have to order more parts
-Designed sturdy and easy to change bumpers
-Reinforced battery mount
-Added removable center belly pan section that allows access to the middle box
-Revised joint layout for improved strength and easier design changes
-Added lightening holes in larger wood parts

We plan on sharing photos and the latest version of the CAD files tomorrow afternoon and our engineering journal at the completion of the project.

Any questions or ideas?
