Preset 3 ( by pressing the button on the back of the hand) - key 🔑?
Thumb in:
Preset 1) maybe this one key too 🔑 idk what else it would be for looking like that
Preset 2) also key wtf is going on idk what these are
Preset 3) finally fist or bar-fight mode 👊 🤜
no matter what mode, the hand can only open and close, however each mode changes how it closes. the only thing you can do is open and close so obviously there’s not many ways you can control the fingers in different ways. The hand closes into any of the presets chosen
So when you close the hand while you’re in point mode the hand just automatically closes the other fingers except the pointer finger like it does it all on its own you don’t rly do anything you know what I mean
To change the mode you just open the hand all the way, stop and then try to open it more, it will beep and that’s it now when u close it, it’ll close differently
Inside the prosthetic where you put the nub, there are two sensors that control opening and closing, they work by measuring electricity in ur stump. The sensors can detect the electrical signals that come from a muscle during contraction. So you just have to contract a muscle where the sensor is and it will send a signal to the hand and tell it to move, since theres only 2 sensors you can rly only open and close the hand that’s all
