Abstract
Certain embodiments of a system for reducing backlash include a member geared for rotation in first and second directions. In various implementations, a first motor causes rotation in the first direction with an output biased to preclude space between mating gear components in the first direction, and a second motor, which is mechanically independent of the first motor, causes rotation in the second direction with an output biased to preclude space between mating gear components in the second direction.
