Gripping hand for a manipulator
First Claim
1. A gripping hand for a manipulator, said gripping hand comprising:
- a plurality of hollow members simulating the human hand, including finger members and a hand back member said plurality of hollow members being interconnected in an articulated manner,a reversibly actuated positioning drive and a sensor being associated with each of said plurality of hollow members, said sensors detecting, for programming purposes, movements of said plurality of hollow members derived from a human hand inserted in said plurality of hollow members and signals generated by said sensors determining a program to be later performed by said plurality of hollow members, as controlled by a particular positioning drive,an arm, said plurality of hollow members being detachably connected on said arm and said arm being programmable by the movements of said hand back member, if a human hand performing movements is inserted in said plurality of hollow members and said arm is able to perform movements in three axes which are perpendicular to one another and also rotary movements,a programming means mounted on said arm,a rigid connecting piece connected to said arm, an end of said connecting piece remote from said arm having a first coupling,an end of said programming means remote from said arm being connected to said hand back member facing said arm and said hand back member being detachably connected via said first coupling to said rigid connecting piece, said programming means being detachably connected to said arm, and said rigid connecting piece including a coupling member detachably connected via a third coupling to said connecting piece and carrying said first coupling.

Abstract
A gripping hand for a manipulator which consists of several hollow elements, simulating the human hand, which are linked to one another by articulations, whereby each member has a corresponding, reversibly actuated positioning drive and a sensor. For programming, the sensors detect the movements of the elements which are derived from a human hand inserted in the gripping hand, and the signals from the sensors determine the program which the elements perform, controlled by the relevant positioning drive. The gripping hand is associated with an arm which can be programmed by the movements of the gripping hand, if a human hand describing these movements is inserted in the gripping hand, and this arm can perform movements in three mutually perpendicular axes and rotary movements.

11. A gripping hand on a manipulator adapted to be manipulated by a human operator to perform a task during a programming mode of operation, wherein different portions of said gripping hand and said manipulator are moved during said programming mode and signals representative of the movements are recorded for purposes of later driving said different portions to effect like movements during an operating mode of operation, said gripping hand of said manipulator comprising:
-
a hollow central hand member, a plurality of hollow finger members interconnected sequentially to one another and to said central hand member by a plurality of pivotal joints forming hollow articulated finger units which receive fingers of a human operator and which is capable of movements about said joints through a range of movement corresponding to those of the human fingers during said programming mode, a plurality of finger member sensor elements for sensing movements of said finger members to generate signals representative of said movements during said programming mode, a plurality of finger member driving means responsive respectively to said signals for moving said finger members relative to one another and relative to said central hand member during said operating mode, a rigid connecting piece on an arm of said manipulator, a coupling member which is detachably connected via a first coupling to said connecting piece and via a third coupling to said hand, and programming means on said arm parallel to said connecting piece for programming movements of said arm in three perpendicular axes and around said axes during said programming mode, the end of said programming means remote from said arm being connected to said central hand member. - View Dependent Claims (12, 13)
