This is something we have very little experience with. Any ideas?
We had the same issue with andymark being out of stock on our drive gearboxes, but they should be in by the bext three days

as for your problems., i have seen some teams using the transmissions, not the motors, off of power drills. double check the rules on this but i think the transmissions off of a drill are legal. double check this though.

also, your robot looks a bit top heavy, and excessively tall. maybe consider a shorter superstructure. like this you will probably fall as you cross the bump. also, i dont see another option to lower the ramp. maybe consider moving elements for a lower center of gravity

that being said, you are probably further ahead than we are, but by this weekend we should be back on track. the shooter looks great, and i applaud all teams who are successfully using mechanums, as nobody on my team agrees to use them.

all in all, design looks great, nice to see teams doing robots in full CAD early on. Good Luck to you.
