Rotational flexure pivot

A structure operable to perform compensation movements, the structure comprising:

• an outer member comprising:
• a substantially spherical shape;
• and
• an outer member (OM) cavity;
• an inner member comprising:
• a substantially platonic shape having inner member (IM) corners;
• and
• an IM cavity;
• wherein the inner member is at least partially within the OM cavity;
• wherein the compensation movements comprise the inner member and the outer member moving with respect to one another;
• a flexure system comprising:
• an OM flexure system mechanically coupled to the outer member;
• and
• an IM flexure system mechanically coupled to the inner member;
• wherein the OM flexure system comprises OM flexures having first OM flexure endpoints;
• wherein the IM flexure system comprises IM flexures having first IM flexure endpoints;
• and
• a common flexure endpoint comprising the first IM flexure endpoints co-located with the first OM flexure endpoints;
• wherein the OM flexures comprise a first OM flexure;
• wherein the OM flexure system mechanically coupled to the outer member comprises the first OM flexure mechanically coupled to the outer member;
• wherein the IM corners comprise a first IM corner;
• wherein the IM flexures comprise a first IM flexure;
• and
• wherein the IM flexure system mechanically coupled to the inner member comprises the first IM flexure mechanically coupled to the first IM corner.

A method of forming a structure operable to perform compensation movements, the method comprising using an additive manufacturing device to perform additive manufacturing operations comprising:

• forming a flexure system comprising:
• an outer member (OM) flexure system associated with an outer member;
• and
• an inner member (IM) flexure system associated with an inner member;
• wherein the OM flexure system comprises OM flexures having first OM flexure endpoints;
• wherein the IM flexure system comprises IM flexures having first IM flexure endpoints;
• and
• forming a common flexure endpoint comprising the first IM flexure endpoints co-located with the first OM flexure endpoints;
• wherein the IM flexures comprise a first IM flexure mechanically coupled to the inner member;
• wherein the OM flexures comprise a first OM flexure mechanically coupled to the outer member;
• and
• wherein the compensation movements comprise the inner member and the outer member moving with respect to one another.
