Six degrees of freedom compliant flexure and autonomous assembly using same

Abstract

A flexure having six degrees of freedom is disclosed. The constraint and compliance of the flexure in all six degrees of freedom may be independently tuned for an application. The flexure may include various combinations of sections including, for example, straight arm and curvilinear sections. The constraint and compliance of the flexure is determined by the geometry, cross-sectional area, cross-sectional shape, and material used to form the various sections. A coupling mechanism and a corresponding method for using the coupling mechanism for automated or autonomous assembly of elements using tuned flexures is disclosed. The automated or autonomous assembly of elements employs a coupling mechanism having a motor driven grip and a coupler, in which the coupler includes a six degrees of freedom flexure. The motor driven grip and coupler may optionally include electrical or optical interconnections and self-aligning features.
