Abstract: An articulating multi-body system includes first, second and third bodies, and a displacement clutch. The clutch is mounted to the second body, and includes first and second spools, and first and second cables. The first and second spools include respective first and second mating threads centered about the centerline. The first and second spools are each adapted to rotate about the centerline between fully spooled states, mid-states, and unspooled states. The first and second cables extend between, and are connected to, the respective first and third bodies and the respective first and second spools for cable spooling. A maximum axial distance exists between the first and second spools when in the fully spooled states, and the first and second spools make axial contact with one-another when one is in the fully spooled state and the other is in the unspooled state.
