Body Integrated Programmable Joints Interface
summary
A wearable, reconfigurable joint array built from 11 servomotors straps onto the forearm and folds into a wristband disengage state, driven by muscle EMG signals picked from the forearm. EMG shows low correlation with finger gestures so the machine joints control independently, enabling demonstrated uses: extra fingers that hold objects, a structural support for one-handed note-taking, and a programmable haptic joystick for VR. A small user study and cited monkey work suggest rapid neural adaptation.
