Abstract

Origami combination is reliable because of great stabilization and controllable deployable. Potential and extensive applied in medical field, as a soft robot gripper. To investigate a possible stabilization structure, this design contained a combination of three four-crease vertexes, one five-crease vertex and one six-crease vertex. The design theory is based on waterbomb pattern design and obey the two design principles. The degree of freedom in this combination would be proof is zero, which demonstrates an over-constrained structure, and also the poor control performance and reliability. The reason might be the compelling in five-crease vertex and multiple Dof in the four-crease vertexes (which might be one Dof), which cause the overall outputs dihedral angles could not be controlled by overall inputs. Additionally, this design has faster equilibrium state because of smaller dihedral angle (smaller than 90 degrees) in each vertex, as an overstrained structure. The future improvement might be done by reduce the Dof in the four-crease vertex and promotion in five-crease vertex.
