Success for the robot arm controlled by thought of Chalmers University

Prothese robotique ChalmersIn January 2013, an amputated right arm Swedish was the first man to see graft a robotic arm controlled by thought. Nearly two years later, the balance is surprisingly positive. Placed directly on the humerus and connected with his nerves and muscles interface seems to work perfectly. Not only the patient can now operate the front arm robot by thought, but its interface allows him to regain a certain sensitivity. The time of cyborgs is well and truly arrived.

A major step forward in the control by the thought of robotic prostheses

The neuromuscular interface developed by Max Ortiz Catalan, researcher at the University of technology of Chalmers (Sweden), seems to be a success. Through this interface, the robotic prosthesis wearer can grab objects, tie his shoelaces, lead a normal life. Just it ” plugger ” his forearm robotic interface referred to the bone in his arm to regain the use of this member amputated more than 10 years ago. The patient even demonstrated that he was fit to hold a physical occupation such as truck driver with his prosthesis. The interface created by Max Ortiz Catalan is bidirectional: bearer can not only control the hand, but also feel the sensations from sensors placed on the prosthesis. It is allowing it to be able to take an egg without breaking it or using a drill.

The bearer of the robotic arm was able to perform the physical tasks of a truck driver with its robotic arm.

The results presented by researchers at Chalmers are extremely impressive if compared to the experiments carried out in recent years from brain activity sensors (EEG) or results obtained with a chip implanted in the brain as tempted by DARPA. ” We see this technology as an important step towards a more natural to artificial limb control ,” said Max Ortiz Catalan in the official communiqué of the University. “This is the missing link that will allow interfaces neural take control of sophisticated, hearing what was possible only in short experiments in controlled environment so far ” concludes the researcher.
