Need a hand?
Well, unless you live really close to where I am, my arm probably reach you in time even if I shipped it by air. BUT, that’s why I have made this instructable on how to make a robotic hand using 3D printed components. Fully actuated, individually controllable fingers! Now, you can make your own robotic hand that’s ready to lend everything it has at your aide (well, it is just a hand), so that you don’t have to go around borrowing hands from other people.”
