Use a MiniCIM in a VersaPlanetary instead. Will save your bacon at your first regional.

I fail to see how a bag motor isn't robust enough for an intake roller. MiniCIM is more robust for sure (based on it's power/weight ratio), but that doesn't mean the bag is a bad choice.

We burnt out one on an intake-related mechanism last year. Granted, part of this was to suboptimal friction within the system, but we ultimately just needed more power. Because the motor allowances are the way they are, MiniCIMs generally carry more advantages this year.

Have you checked out the dual motor input for the VexPlanetary? The BAG motor runs much cooler than a Banebot motor. We have had to fan cool the Banebot motors being used in a high torque on/off process.

A cool design would be to use one transmission to ready the catapult, shift and lower the collector arm then run the roller.

Anybody ever build a 3 speed with neutral dual motor PTO transmission?

Roy,

Why do need a 3 speed? A 2 speed with a neutral/3 position would work for almost any first application.

RC,

Just thinking out loud.

Engage gear to arm the launcher,
turn gear to bring launcher arm back
at load position lock the arm with cam
shift to engage intake arm gear, two belts are driven at 15:1 to hit the sweet spot for the bag motors.
to forward roller arm, and turn the roller . The belt for the arm is on a clutch once the hard stop is reached it clutches the belt but the roller keeps rolling to intake.

Two motors + 1 transmission=cool design

PS> RC the Versa blocks are super cool. Great idea. You could extrude the design to reduce the manf. costs. All you need to do is obround slot the tubes and teams wouldn't even need to cut holes into the tube. I could have a tool made to progressive punch the slots.
