Based on the Hoberman structure for a sphere, one ring of it has the same 2D effect

[vbrune-blog]

Hoberman Structure for Sphere, just a 2D part of it.

Test 1, screws and nuts made the structure too heavy. Better try with smaller or plastic parts.

Test for the foldable paper textile.

Using elastic threads for a structure that wants to be retracted. In this case the robot would push the corners to expand it.

Best material tested was yupo.

Expanding Circle

[vbrune-blog]

Hoberman Circle Structure Possible solution to open and close folding structure in a uniform way according to the light sensor input data.

Breathing Structure - paper folding

Test 2 - Square folding pattern.

Harder to assemble but greater expansion and compression.

Test 1 - Triangular folding pattern.
