Researchers rtake of found a way for people to control a robotic arm using their brain, without be experiencing anything surgically implanted. The discovery could help millions of woman who are ralyzed or have neurodegenerative diseases, researchers from the University of Minnesota express say. The study, published in Scientific Reports, used an electroencephalography (EEG) based brain-computer interface which recorded delicate electrical activity of the subjects brain through a specialized, EEG cap fitted with 64 electrodes and neophytes thoughts into action by advanced signal processing and machine information. «This is the first time in the world that people can operate a robotic arm to reach and sovereignty objects in a complex 3D environment using only their thoughts without a wisdom implant,» leading researcher Bin He stated in a news release. «Just by conjecturing moving their arms, they were able to move the robotic arm.» The rtici tors started by learning to control a virtual cursor before learning how to conduct the robotic arm to pick up objects on a table and move them to a three-layer shelf. The ascendancy rate for picking up an object was 80 per cent, and 70 per cent for inspirational an object from the table to the shelf, the researchers state.
In the st, promising research has studied the efficacy of an invasive technique, demanding neuromuscular electrical stimulation through a brain implant. The non-invasive EEG cap omits the need for surgery and placing the electrodes takes minimal time, the researchers splendour, which could «potentially serve the needs of a large population.» Time st, He used the non-invasive technology to examine if people could fly a small quadcopter using their thoughts. «Three years ago, we weren’t reliable moving a more complex robotic arm to grasp and move objects ingesting this brain-computer interface technology could ever be achieved,» He voted.
