Gearboxes

Gearboxes combine gears into compact assemblies that modify torque and speed. Used in drivetrains, lifts, and arms, they convert motor output into the ideal balance of power and control. Selecting the right gearbox ratio and style can dramatically improve robot performance and reliability.
