The origami “magic-ball” 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
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.
The origami “magic-ball” can exhibit a significant radialcontraction with a volume reduction of more than 90% .Furthermore, if one end of the origami “magic-ball” is fixedand closed, then the other end can be opened to form ahollow hemispherical shape

Croatian waters are home to several shipwrecks and local heritage organizations are leveraging the performance of 3D scanning to document and even restore ships that were lost so long ago.
Paravan has already been using Creaform 3D measurement technology for several years and has recently added the Go!SCAN SPARK white light scanner to its measurement technology portfolio.
Virtual reality (VR) is no longer the sci-fi dream promised to many for decades, but never quite delivered. In fact, 2016 could even be the year of VR. CNN Money, among others, named it one of its only two biggest tech trends this year
