Our team is using motor sharing with pneumatics (sliding PTO). This allows us to power the catapult and H-Drive using 1 motor (we’re at the max 6). The movement of the pneumatics and gears works fine, the input motor power correctly transfers to one of 2 drive shafts.
The problem is the one of the shafts has a 90 degree turn and there we get the bevel gears slipping (we’re using bevel gears). We kept the catapult straight, and have the 90 degree turn assigned to the H-Drive so the catapult is not low on torque. There’s a clicking noise at the bevel gears and they slip, the H-Drive doesn’t move. If the robot is lifted in the air so there’s no friction then the H-Drive wheels turn.
I have tried regular gears at the 90 degree angle, crown gear + regular gear, and finally bevel gears - all are clicking at the turn. What can we do?
We have a tournament on this Saturday and don’t know what to do. The H-drive is critical to helping the robot align with the goal in autonomous and the kids on our team have also been using that extensively during driving skills so we don’t want to ditch it. Any and all ideas would be very appreciated!
