Researchers sponsored by the Pentagon developed an artificial hand that communicates bidirectionally with the brain like a human hand.
After decades of research, a artificial hand that is controlled with the mind and has sense of touch. According to its developers I was able to function as a human hand since it connects to bidirectional nervous system.
Research published in ArXiv highlighted that hand robot is a breakthrough since it is capable of transmitting the touch sensation and has a near perfect response time.
“It can transmit the sense of touch using electrical stimulation over the same Scorpius nerve interface, which has both neuronal and stimulatory receptors,” says Dr. Anh Tuan Nguyen, from the Department of Biomedical Engineering at the University of Minnesota.
The artificial hand It is part of the project called Draco and it is the third generation to come forward. It is part of the studies sponsored by DARPA, the advanced research arm of the Pentagon.
Its developers highlighted that there is still work to be done since at the moment it does not have the flexibility and sophistication of a human hand.
How does the artificial hand that is controlled with the mind work?
The artificial hand It has an interface called Scorpius, it is a series of microelectrodes implanted and connected to the peripheral nervous system.
Scorpius picks up the electrical impulses sent by the brain to the amputated hand and transmits them to the electronic circuit. Here the artificial intelligence is in charge of interpreting these impulses.
For this, the AI is based on previous learning to be able to get each finger to move individually according to the wishes of the user. Its developers emphasize that artificial hand I was able to move with an accuracy of 95 to 99%.
Draco would have a latency (time from when the brain issues the command to the finger’s reaction) is 50 to 120 milliseconds, somewhat slower than a human hand.
The artificial hand it also has touch sensors built into the fingertips.
“The neural processor receives the signals from the sensors and performs a reverse translation job, ordering Scorpius to send nerve signals that the brain interprets as the sense of touch”
The creators emphasize that the learning models are developed on a computer so they can be automatically downloaded to the artificial hand with a wireless connection. In this way, its operation is improving.
Its developers highlighted that artificial hand It still lacks work in both its appearance and its function, as it has durability problems.
