Abstract:
1. A gimbal ball, comprising: an inner gimbal; first and second inner driver components mounted to the inner gimbal; an intermediate gimbal rotatably connected around the inner gimbal; an outer gimbal rotatably connected around the intermediate gimbal; and first and second outer driver components mounted to the outer gimbal, each outer driver component extending at least partially through an opening of the intermediate gimbal to operatively connect to one of the inner driver components; wherein the first inner and first outer driver components are collectively configured to rotate the inner gimbal relative to the outer gimbal about a first axis while leaving the intermediate gimbal in a fixed orientation, and the second inner and second outer driver components are collectively configured to rotate the inner gimbal relative to the outer gimbal about a second axis while leaving the intermediate gimbal in a fixed orientation.
