Flexy-Hand is a 3D printed prosthetic hand with stretchable artificial tendons
Prosthetic hands give the unfortunate people who have lost their limb in accident or those who have some deformity from birth, a new lease of life as they thank technology for making their life normal. In the past few months we have seen lots of prosthetic hands developed by geeks who want to change the world for better and some have even provided open source information on how others can improve and make a better version of their prosthetic hands. Combining the possibilities of 3D printing and robotic hand, Steve Wood has made his own version of a prosthetic hand known as Flexy-Hand that looks amazingly close to what a real hand would be like. It took only 20 hours to 3D print this open source prosthetic hand after a day’s design routine.
World’s first artificial hand with flexible tendons that ensure smooth movement just like a real hand.
Not only does it look like a real human hand but also functions like one. Wood used flexible filament that function as tendons to operate each finger separately for a much more realistic approach to making a prosthetic hand. These artificial tendons are so flexible that they can’t be broken in any case, giving flexibility in movement and the servo motors actuate their movement for perfect human-machine interaction. Wood calls it the adaptive grip technique with frictionless articulation which makes the prosthetic hand grip objects much like our real hands do.
Flexy-Hand is made from self-securing 3D printed parts that eliminate any bulky nuts or bolts to secure the different parts together. This makes the hand completely flexible without the need of any rubberized parts or springs.
