Magic-ball  Soft  Gripper

The origami “magic-ball” &nbsp;is a well-established origami design. It is folded from a rectangular piece of paper pre-creased with a repeating waterbomb pattern that is offset by a half-unit on every new row. The waterbomb pattern features a square with folds along its diagonals and a vertical axis of radial symmetry. This “magic-ball” structure can be reversibly changed between a spherical shape and a cylindrical shape, therefore it has been utilized previously in the development of morphing robots&nbsp;The gripper-to mount connector is surrounded with silicone skin. When the gripper closes in on an object, a vacuum collapses the silicone around it, effectively grasping the item without crushing it—and it’s capable of doing so for objects that are up to a hundred times its own weight.&nbsp;The origami “magic-ball” can exhibit a significant &nbsp;radialcontraction with a volume reduction of more than 90% [30].Furthermore, if one end of the origami “magic-ball” is fixedand &nbsp;closed, &nbsp;then &nbsp;the &nbsp;other &nbsp;end &nbsp;can &nbsp;be &nbsp;opened &nbsp;to &nbsp;form &nbsp;ahollow &nbsp;hemispherical &nbsp;shapeRead the article about this project <a href="https://www.wevolver.com/article/a.soft.and.strong.robotic.hand" rel="noopener noreferrer" target="_blank">here</a>.
