COMPLIANT JOINT WITH THREE DEGREES OF FREEDOM

Disclosed herein is a compliant joint that is movable in three degrees of freedom (DOF), as well as systems including the compliant joint, and a process for assembling the compliant joint. The compliant joint may comprise an elongate arm, a ball joint, and a carrier. The ball joint is configured to couple to the carrier, and the elongate arm is configured to couple to the ball joint. The ball joint may have a cross section that is ellipsoidal, an outer surface that is convex, and a first hole. The carrier may comprise a second hole that is ellipsoidal, and an inner surface that is concave. The elongate arm, when disposed within the first hole, is movable axially through the first hole, and the ball joint, when disposed within the second hole, is movable with at least one of pitch rotation or yaw rotation.
