There is no "need" to remove the gearboxes or use magnets to make a sub 2 sec minibot.

Gearboxes that are modified to a 10.4 to 1 ratio, custom PVC pipe wheels, weight around 3lbs and rubber bands to provide the normal force for traction is how we made very consistent ~1.8 sec minibots that do reliably trigger.

We did try a couple of iterations of rod wheel minibots but they were no where near as consistent for us....yet.
