Abstract
Disclosed is a system, method and apparatus for dynamic management of haptic module mechanical offset with gravity-induced position offset tracking. In an embodiment, a method comprises: determining, by a processor, a gravity-induced position offset of a mass in a haptic module; generating, by the processor, a position command for moving the mass from a sensor reference position to a mechanical resting position based at least in part on the gravity-induced position offset; and moving, by a closed-loop controller, the mass from the sensor reference position to the mechanical resting position in accordance with the position command.
