A Smart Artificial Hand For Amputees Merges User And Robotic Control

EPFL scientists have successfully tested new neuroprosthetic technology that combines robotic control with users’ voluntary control, opening avenues in the new interdisciplinary field of shared control for neuroprosthetic technologies.

This interdisciplinary proof-of-concept between neuroengineering and robotics was successfully tested on three amputees and seven healthy subjects. The results are published in today’s issue of Nature Machine Intelligence.read more: EPFL

The amputee must perform a series of hand movements in order to train the algorithm that uses machine learning. Sensors placed on the amputee’s stump detect muscular activity, and the algorithm learns which hand movements correspond to which patterns of muscular activity. Once the user’s intended finger movements are understood, this information can be used to control individual fingers of the prosthetic hand.

The algorithm developed kicks in as soon as the user tries to grasp an object. It tells the hand to close its fingers when the object comes in contact with the sensors. The above video shows this artificial robotic hand in action.via/read more: EPFL
