1. A method comprising:
accessing a target value for a gear system, wherein the target value comprises a target backlash or a target preload, and wherein the gear system comprises a driving gear configured to rotate about an axis, a driven gear, a preloading actuator coupled to the driving gear, and a preloading actuator controller;
determining a measured value for the gear system, wherein the measured value comprises a measured backlash or a measured preload;
determining that an error value between the measured value and the target value exceeds a threshold error; and
sending, by the preloading actuator controller, instructions to the preloading actuator to adjust the driving gear by translating the axis of the driving gear in response to determining the error value between the measured value and the target value exceeds the threshold error.
