Scientists develop robotic hand for people with quadriplegia

The battery-driven hybrid EEG/EOG-based brain-machine interface. Solid gel electrodes – attached to a noninvasive mesh cap worn on the head – sent measurements of electric brain activity and eye movement to a computer tablet, which then translated these quantities to control signals for the robotic hand attachment.

The low-cost device was tested in Spain on six people with quadriplegia affecting their ability to grasp or manipulate objects.
By wearing a cap that measures electric brain activity and eye movement the users were able to send signals to a tablet computer that controlled the glove-like device attached to their hand.
Participants in the small-scale study were able to perform daily activities better with the robotic hand than without, according to results published Tuesday in the journal Science Robotics.The video will load shortlySurjo R.
