Here is the first iteration. I decided to go a different direction this time given the suggestions received in the linked thread.
Here* is the second iteration.
Specs:
68 lbs including pneumatics, and all electrical components. This number is before any pocketing is considered.
Everything can be built with simple power tools plus a mill (lots of milling...).
10 Wheels including six 4" Omni wheels and four 2.5" custom wheels fabricated from Delrin.
In omni mode: the drivetrain has a 14:64 gear ratio which equates to about 16.5 ft/s Adjusted Speed according to the JVN Calculator.
In traction mode: There is an additional 18:30 reduction which, along with the difference in wheel size equates to 6ft/s Adjusted Speed.
The strafe wheels are pneumatically actuated, powered by a cim motor, and geared at 12:64 which is around 14 ft/s Adjusted Speed based on the JVN calculator.
Improvements over Iteration 1:
- The strafe wheels are now pneumatically actuated so as to main in constant and consistent contact with the ground
- I hid basically everything, maximizing space for other components
- The new frame is much easier to mount things to
- No weird moments to worry about as nothing is cantilevered... or double cantilevered...
Huge shout out to Aren Hill and 3928 Team Neutrino. A lot of this design was inspired by their 2013 drivetrain.
What am I missing? Where am I going wrong? What can I improve? Thanks for the feedback!
*Sorry for the lack of a quality render. It's 3AM and I'm bad enough at rendering when I'm wide awake.
