Re: Shifting while not going straight
For logomotion, my team had a shifting and braking mecanum drivetrain. We used AM Supershifters with 1 cim on each wheel, and went for the pneumatic option to shift. I don't remember having any issues with shifting while the robot was rotating or doing anything else. The lower gear was mostly used for fine control while hanging game pieces. A student on our team also made brake pads for each wheel out of extra mecanum wheel plates, which immobilized the rollers to increase traction, and were also engaged by small air cylinders. Lots of pneumatics, but it did what it was supposed to do, and we won a Creativity Award for it.
