bobby lets me test drive the mpl. first, he places arm band sensors on me. like my prosthetic arm, these bands contain electrodes, which record andranslate the muscle activity in my little arm. - we use electrodes that can pick up what's called the bio-potentials of the human body, it's sort of the electricity that is flowing through your body to send commands to and from your brain. - with eight times as many electrodes as my arm, these bands allow for much finer pattern recognition from my muscles. - instead of just piing up gross muscles, so these big muscle movement it's picking up smaller, fin things. today, i'm getting a feel for some novel gestures and new capabilities. - all right, so when you're ready, you're gonna start recording. no movement orest state. - okay. (hand whirs) - well that's okay, it's learning the first time. so it may sort of confuse what you're doing, 'cause it's never seen this pattern before. you're introducing something new. - a computer inside the mpl reads the muscle movements from my arm and translates these complex patterns
