AI Can Literally Lend You a Hand #kurzgesagt #shorts

AI can literally lend you a hand, but hands are complicated. If your hand were a video game character, you'd need 27 buttons to control it. Millions of possible button combinations need to be translated to a robotic hand in real time, with as little delay as possible.

So for the past 60 years, researchers have basically been working through one combination at a time. AI comes in handy by speeding up the process. Learning the move set from a healthy hand and adapting it to a robotic hand is much faster now.

So how does it work? What you need is one healthy hand to wear a data glove and a microchip riddled with a bunch of electrical sensors in your residual limb. Many of the movements of your hand are made in tandem with muscles in the rest of your arm.

When you try to move your missing hand, the sensors on the chip read these movements and send them to a machine learning algorithm. After an initial training phase, it can translate these signals into moving a robotic hand that's connected via Bluetooth. And just like that.
