Reconstructing the First “Iron Hand” of Knight Götz von Berlichingen and Its Derived Modern Developments: Back to the Future

Low-cost 3D-printed motorized hands, controlled by optical see-through glasses and driven by energy-efficient neural network platforms, could have an impact. Furthermore, personalization has yet to become a topic, and therefore we developed personalized hand prostheses, in which the healthy (real) hand is scanned using a 3D light scanner, the data mirrored to replace the amputated hand, processed in computer-aided design (CAD), and then 3D-printed from flexible material (Figure 3) [6,7] or used to create a personalized, 3D-printed mold for casting. The prosthesis markers (in red) are tracked with the camera integrated into the AR glasses, enabling the evaluation of relative movements between the AR glasses and the prosthesis.
