Scientists and engineers have gone one step beyond creating replacement robotic limbs via the amazing contraption you can check out below.
Science and technology have come so far in so many ways over the last couple of decades, but the most important advancements by far are the ones made in the medical field. The curing of diseases and the overall improvement of health care. Life expectancies continue to improve and modern medicine obviously has an awful lot to do with that.
Another field that continues to excel is robotics, and there are actually a few ways in which that world and the medical one can work together. Perhaps the most remarkable advancements in the area where these two spheres cross is the progression of artificial limbs. Those who have lost an arm or a leg no longer have to rely on crude, plastic replacements that aren't really like the real thing at all.
The robotic limbs being developed are pretty incredible, and now there's a brand new limb that isn't even necessarily for those who have one missing. It's a robotic double hand, and how it works is pretty astounding. As you can see from the video below, the wearer has the ability to control both hands at the same time depending on how he or she moves their fingers.
The 3D printed extra limb has been created by Youbionics, and the above clip of it in action comes courtesy of Mashable. It works by using flex sensors on the user's fingers and as you can see, even though it is only attached to one real hand, both robotic hands are in play. Which hand you control and what you make them do depends on how you move your fingers and also the speed at which you move them.
The movements and controls for the double hand all seem pretty complex and elaborate, but it is an extra limb after all. If it was easy to control then it would have been created years ago and we would all already have them. While right now it's just a great way of grabbing multiple things at once, Youbionics believes that it may be the next step towards creating the first augmented human.
