Fully floating, self-aligning, self-adjusting gimbal assembly for an active human machine interface

A human-machine interface assembly is implemented with a gimbal assembly that includes a roll hub, a pitch hub, and a main hub. The gimbal assembly further includes a plurality of bearings, and is mounted via a plurality of bearing sets, that are each disposed in a free floating manner. As a result, each of the bearings is self-aligning and self-adjusting when the gimbal assembly is assembled and mounted. The gimbal assembly additionally includes a plurality of integral stops that mechanically limit movement of a user interface to predetermined pitch and roll angles.
