The devices are floating engageable means which may be a floating nut or a floating driver for use in hostile environment, such as space. The device includes a housing with a cross-shaped opening, each arm of the cross receiving a wing of a floating member. A spring between the base of the housing and the back of the floating member urges the wings against the top surface of the arms of the cross-shaped opening in the housing. The cross-shaped openings may have a rectangular configuration with a thread surface forming the top surface of the opening. This permits the floating member to maintain a lateral offset. Alternatively, the arms may have a triangular outline with the vertex forming the top surface of the arms. With this configuration, a force will be provided to center the floating member in the housing. The floating member terminates in a an outwardly facing taper guiding surface which tapers to the engaging means of the floating member. With this arrangement, off axis and off angle mating is possible.

Floating Matable element

An extensible articulated manipulator arm is described in which the distal end is movable in a straight line relative to the proximal end thereof. The articulated arm includes a first arm which incorporates a first parallelogram linkage and a second arm which includes a second parallelogram linkage, the adjacent ends of the parallelogram linkages are drivingly connected to one another whereby rotation of the first arm about the first end support alters the geometry of the first parallelogram linkage which in turn effects a corresponding alteration in the geometry of the second parallelogram linkage, thereby to cause movement of the distal end of the second arm in a straight line relative to the proximal end of the first arm.

Mechanical arm assembly

A grappling device that is light-weight is formed with a light weight head. The interior of the head has three cables attached to two spaced rings so that rotary movement of the rings move the cables to open or closed configuration.
