For the first time successfully built robotic arms with human touch

Tactile will be used as an alternative arm for the disabled, besides it helps to get closer to creating a robot that feels natural like a human.

A woman who had an accident and lost her arm 20 years ago received an artificial arm, through tiny electrodes and sophisticated sensors, she regained the feeling of touching or touching one object.

This technology uses sensors at the tip of the artificial hand to receive information when touching objects, and then uses an internal computer to convert them into languages ​​that the brain can understand. and inserted into the human body through electrodes.

This breakthrough is the result of many years of robot research done by researchers from Italy, Switzerland and Germany. Almerina Mascarello, who was chosen for this creative experiment, went with the team for 6 months.

Sharing with the BBC, the girl said: 'With this artificial arm, I have regained the joys in life. Simple tasks like dressing or tying my shoes, now I have done it myself. Although it's simple, it means something to me. '

Paolo Rossini, neurologist at Agostino Gemelli University Hospital in Rome, saw the great potential of this technology. He said: 'Once we can control these artificial parts and make the brain understand, then we will go further with complex activities and not simply hands with five fingers. '.

This artificial tactile technology has been developed since 2014, but at this time, the auxiliary devices are too big in size, making the arm unable to guarantee mobility or even being unable to carry it. out of the lab.

Dennis Aabo Sorensen, who lost his arm in a firework 2014, said it was great to have the touch back.'I can feel different materials, knowing that the object is hard or soft, or even I can handle it in my hand.'

The researchers found Dennis could distinguish the rigidity or softness of a true object by up to 78% during the test. In addition, he can accurately describe the size and shape of the right object up to 88%, specific objects such as baseball, glass jars or oranges.

He was in the trial in 2014, at which time he had to carry a large computer in his backpack behind his back to transmit signals from the artificial hand.(Photo: Cattolica News).

Researcher Silvestro Micera of neurology at EPFL in Lausanne said: 'We aim to be as creative as science fiction films, artificial parts like Luke Skywalker's arms but can hold grip and touch like a human hand '.

After testing on humans, Almerina must return the design to the researchers. Even so, the girl still hopes that the official version will soon be released and commercialized, she will buy a set and wish every disabled person in the world will be able to use it.
