There are now countless versions of 3D printed prosthetics out in the world, so many so that we come across new ones each day. Just yesterday, one solid Metal Gear Solid fan actually had his own 3D printed prosthetic made, versioned after the game. Now, two researchers of University of Washington, Zhe Xu and Emanuel Todorove, have directed their focus on the biomimetic functioning of the human hand, creating what may be the many “human” anthropomorphic robotic hand at any time made. Before constructing the robotic hand, the duo started with a laser-scanned human skeleton hand. Xu and Todorove and so 3D printed artificial bones that were versioned after the scan, that enabled them to duplicate the hard unfixed joints we have in our hands.
“We 3D print artificial bones of the laser-scanned version of a cadaver skeleton hand and connect them with artificial finger joints whose range of motion, stiffness, and dynamic behaviors are quite close to their human counterparts,” said Zhe Xu. “Our robotic hand create uniquely preassists the significant biomechanical information of the human hand on anatomical level.”
In addition to the 3D printed artificial bones, the researchers made joint ligaments, extensor, and flexor tendons for the hand with Spectra string, that is a lightweight and high-strength fiber-based gel, and replicated soft issue with laser-cut rubber sheets. The final piece introduced the biomimetic hand were the ‘muscles’ that were replicated by the cables of 10 Dynamixel servos, that are capable of replicating the carpal tunnel of the human hand.
What’s awe-inspiring of this anthropomorphic robotic hand is not only that it’s created like an actual human hand, but it operates as one as well. This exact biomechanical function has much additional to do with the high end construction of the hand, that is based upon the 3D printed artificial bones, additional so the any type of programming. But the hand is regulated by the researchers through telemanipulation, that allows for them to control the robotic hand with their own hand movements, they in addition feel as if the robotic hand research can soon be utilized in limb regeneration research. The researchers feel that their biomimetic hand may be utilized as 3D scaffolding for biocompatible materials, that may assist the human brain to advantageous control prosthetics in the near next.
“All of the these promising technologies need suitable scaffolds for the growth of grafted cells,” introduced Xu. “We are going to collaborate with researchers of biology and tissue engineering to additional explore its future to assist as a bio-fabricated device/scaffold in the emerging fields of neuroprosthetics and limb regeneration.”
The full research report, that is entitled “Design of a Highly Biomimetic Anthropomorphic Robotic Hand Towards Artificial Limb Regeneration”, can be presented at ICRA in Stockhold, Sweden, this coming May.
