Abstract
Abstract A deformable remote center compliance device including operator means, at least a portion of which is deformable, and having a first motion center; and a deformable support means for supporting the operator means to permit rotation about a projected second center and providing in conjunction with the operator means a remote center of compliance between the first and second centers at, near, or beyond the end of the operator means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
A deformable remote center compliance device comprising: a base; an intermediate member; deformable support means disposed along radii from a first motion center interconnected between said base and said intermediate member; and operator means having a first upper rigid portion interconnected with said intermediate member and a second lower deformable portion having a second motion center for establishing a remote center of compliance between said first and second centers of motion at, near or beyond the end of said operator means; said lower deformable portion having a reduced cross-section relative to said upper rigid portion.
Claim 2
Dependent Claim
95 words
A deformable remote center compliance device comprising: a base; an intermediate member; deformable support means disposed along radii from a first motion center interconnected between said base and said intermediate member; and operator means having a first upper rigid portion interconnected with said intermediate member and a second lower deformable portion having a second motion center for establishing a remote center of compliance between said first and second centers of motion at, near or beyond the end of said operator means; said lower deformable portion having a reduced cross-section relative to said upper rigid portion.
Claim 3
Dependent Claim
21 words
The remote center compliance device of claim 1 in which said lower deformable portion is tapered to produce said reduced cross-section.
Claim 4
Dependent Claim
22 words
The remote center compliance device of claim 1 in which said lower deformable portion is centrally bored to produce said reduced cross-section.
Claim 5
Dependent Claim
19 words
The remote center compliance device of claim 1 in which said deformable support means includes a plurality of elements.
