Folding


Folding is the process or reducing the volume occupied by a structure. Folding tensegrities requires a different approach from conventional or pantographic folding.

Tensegrity Folding Classifications


Folding can be divided into the following three steps (following Motro)
  • Algorithm or mechanism selection
  • Verification of system compatibility during folding
  • Stabilizing or re-stressing the system after folding

Three modes may also be abstracted, again following Motro
  • Strut mode
  • Tendon mode
  • Mixed mode

Motro's Discussion of Folding

Motro notes in his book Tensegrity , chapter 6-2 "Folding Principle" that folding requires modifying element lengths and granting the corresponding degrees of freedom to the vertices. As the tensegrity is folded the nodes follow a trajectory through space.
