Guided Hand Robotic 3D Printer
3D pens are nothing new. Many use them to build models quickly. They are not always easy to control or accurate. The Guided Hand 3D printer is a robotic system that allows artists and designers control a 3D pen in a more efficient, accurate manner. It relies on a haptic feedback device, the Geomagic Touch, to allow users the sensation of touching digital models.
The above video shows how Guided Hand works. Yelizk.com has more on the story.
