The sequence of operations of the gripping and locomotive modules can be controlled such that the robotic apparatus can crawl through the enclosed space in an inchworm-like fashion and is capable of navigating turns and traversing inclines.

Abstract: A linear drive unit has a threaded rod, and in combing engagement with same a threaded nut (2), from the outer circumference of which a number of equally spaced cogs (3) project in a radial direction. Furthermore, connecting links (4, 5), which extend parallel to the axis of the threaded rod inside a housing, are driven via hydraulically or pneumatically actuated pistons, causing the connecting links (4, 5) to move in an axial direction. During this oscillating movement the connecting links act upon cogs (3) that project from the threaded nut (2). The force exerted via the cogs (3) located on the outer circumference of the threaded nut (2) causes the threaded nut (2) to be put into an incremental rotation, which, in turn, causes an incremental linear shifting of the threaded rod (1).

Abstract: A push-pull coupling for coupling a valve spool to a coaxial cable includes a lost-motion connection which operatively disconnects the coaxial cable from the valve spool when in a first mode and positively connects the coaxial cable to the valve spool when in a second mode. Switching from the first mode to the second mode is accomplished by energizing an electromagnetic actuator within the coupling which locks components to one another to transmit push and pull motion. When the actuator is deenergized, the components move relative to one another, disconnecting the coaxial cable from the valve spool. The push-pull coupling is used in hydraulic machines to prevent operation of hydraulic cylinders when a driver is not seated on the machine so as to close a seat operated switch which energizes the electromagnetic actuator.
