Programmable Anthropomorphic Articulation

US Patent:

40005640, Jan 4, 1977
Filed:

Jan 7, 1976
Appl. No.:

5/647317
Inventors:

Mark P. Haffner - New Carrollton MD
Robert S. Pizer - Washington DC
Assignee:

The United States of America as represented by the Secretary of the
Department of Transportation - Washington DC
International Classification:

G09B 2332
US Classification:

35 17
Abstract:

An anthropomorphic programmable joint joins two limb portions. The joint may simulate the knee joint and the portions may correspond to the upper and lower leg portions about the knee. A magnetic particle brake is attached to the upper portion with a shaft that carries the pinion gear of a bevel gear set located at the joint. The ring gear of the bevel gear set is fixed to the lower limb portion so that rotation of the lower limb portion about the joint causes the shaft to rotate the magnetic brake fixed to the upper portion. The brake resistance to this rotation, and therefore the resistance of the joint to rotation, may be programmed in correspondence to electrical current applied to the brake.
