Abstract
A fixture comprising three plates capable of exercising decoupled motion along three angular axes. A first end of a connecting rod is mounted, by way of a spherical bearing in one of the plates, while an opposite end is secured to the peripheral center of a spherical sector platform. The periphery of the platform is supported on bearings mounted to a rotatable gear which imparts yaw motion to the spherical section. Displacement of the connecting rod causes tilting of the spherical section in roll and pitch directions. Three linear and three rotational degrees of freedom are possible for the platform while maintaining a constant pivot point at the center of the sector's radius of curvature, on the system axis. The pivot point lies above the unobstructed mounting surface of this fixture.
