Perhaps the world's most powerful mechanical arm was developed several years ago in America. Named "O-Man" (for Overhead-MANipulator), this 15-ton remote-controlled giant makes possible the assembly or dismantling of large machinery by the twist of a knob or the flick of a lever. This mechanical "Tarzan" was built as the answer to the need for a device with several times the lifting power of existing mechanical arms, yet with equal verstility.
By comparison, if a man were as strong as "O-Man" he would be able to carry 5,000 Lb. on his back, lift 3,000 lb. from the floor, hold 1,000 lb. with his arm extended horizontally, or lift and manipulate a piano with is forearm and wrist.
"O-Man's" chief job is to pick up heavy parts, position them and fasten them into place. It can drill and tap holes, use power wrenches, hammers, or riveters, and if need be, can handle a sheet metal saw.
While its grip lacks the flexibility of human fingers, it otherwise posesses the same degree of motion as the human hand and arm, plus the ability to telescope its "forearm" and revolve its wrist.
In a special test, it twisted an iron bar into a corkscrew then tied it into a neat knot. Yet, although not intended for delicate tasks, "O-Man", with its twin steel fingers, can whip up, slice, and serve a cake or pick up and pour a glass of water, so refined can its touch be made.
Resembling a gun turret, the big device operates from a crane bridge, its vertical manoeuvrability ranging from floor level to the height of the crane bridge. Power control is supplied by means of 140 separate wires in multi-festooned cable. The heart of the control mechanism is a system of 8 amplidynes–devices that provide automatic control giving smooth operation and limiting all motions to prevent damage to equipment.





General Mills later made the O-Man called Model 700 Manipulator.

1956 – GE Yes-Man Teleoperator – Ralph Mosher (American)

Life Magazine 28 May 1956 p 125.

The disembodied device graciously helping the girl with her coat (above) is one of the most dexterous robots yet designed. Its arms have elbows that bend, wrists that swivel and three-clawed hands. Still being perfected by G.E., it is an electro-mechanical slave called the Yes Man which does the bidding of a human master who acts out the desired motions in pantomine. Attached in the master's hands are a pair of arms matching the robots. When the man moves his fingers, electric signals activate hydraulic pistons which move the Yes Man's claws the same way. Through a feedback system, the operator can feel what the robot is doing. Yes Man has a serious purpose. By watching it through TV, a technician sitting some distance away could safely guide the Yes Man through intricate tasks in an atomic laboratory.

The above article from "The Herald Journal", 24 May 1956.

Schenectady 5, N. Y.
SCHENECTADY, N. Y. — "Yes-Man," the most dexterous mechanical slave ever developed, helps pretty Ruth Feldheim into her coat during a demonstration at General Electric's General Engineering Laboratory. As Ralph Mosher, a G. E. engineer operating the "master," goes through the motions of helping Ruth into her coat, some distance away, the "slave" does the real job deftly and politely. The master-slave manipulator, designed to perform mechanical tasks in hazardous radioactive areas, is the strongest and most dexterous yet developed. It was built in the engineering laboratory for G. E.'s Aircraft Nuclear Propulsion Department under an Air Force contract.

The above GE press photo says that Ralph Mosher is responsible for this machine. See below for other, similar machines by GE and Ralph Mosher.

I have very little information on this teleoperator.  From what I have found, only the Goertz manipulators were earlier with force-feedback.
