ABSTRACT:
A sealed joint having two adjacent, axially aligned sleeves separated by a rotating seal, one joint being movable with respect to the other. The joints contain a tubular passageway surrounded by a motor and a harmonic drive. A tachometer and a brake help to control the motor and a position encoder measures rotational motion between the sleeves. All components are mounted in sealed relation with respect to the outside of the sleeves. A sealable port communicates with the interior of the tubular passageway for each sleeve so that control cables and fluid conduits may pass into the joint through one port, along the tubular passageway and out of the other port.
