Abstract
Abstract An artificial hand device, particularly for use in robotics, comprises an assembly of substantially parallel pins (1, 2) mounted on a carrier (3, 4) so that the free ends of pins pressed against a given object may move axially to conform to the profile of the object. Means to move lateral surfaces of the pins (1, 2) laterally allows the device to grip the object. Means to detect pin position allows sensing of the shape of the object.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
38 words
An artificial hand device comprising an assembly of substantially parallel pins mounted on a carrier, so that the free ends of pins pressed against a given object may move axially to conform to the profile of the object.
Claim 2
Dependent Claim
38 words
An artificial hand device comprising an assembly of substantially parallel pins mounted on a carrier, so that the free ends of pins pressed against a given object may move axially to conform to the profile of the object.
Claim 3
Dependent Claim
28 words
An artificial hand device as claimed in claim 1, in which means are provided to move pin lateral surfaces adjacent to the object laterally to grip the object.
Claim 4
Dependent Claim
40 words
An artificial hand device as claimed in claim 2 in which the assembly of pins is divided into two or more sets of pins, lateral movement of the sets of pins providing the lateral movement of the pin lateral surfaces.
Claim 5
Dependent Claim
29 words
An artificial hand device as claimed in claim 2 in which each pin may be expanded laterally so as to provide the lateral movement of the pin lateral surfaces.
Claim 6
Dependent Claim
22 words
An artificial hand device as claimed in claim 1, in which means are provided to urge the pins to a datum position.
Claim 7
Dependent Claim
35 words
An artificial hand device as claimed in claim 1, in which pin movement sensor means are provided to enable the profile of an object against which free ends of pins are pressed to be determined.
Claim 8
Dependent Claim
84 words
An artificial hand device as claimed in claim 6, in which the pin movement sensor means are switches; switches for individual pins being in a first state when the pin is at a datum position, and in a second state when the pin has moved from that datum position, means being provided to determine the profile of an object by correlating the distribution of switches in said first and second states with the position of the device in the direction of the pin axes.
