Scientists have successfully developed brain-controlled robotic hands

People who are busy often complain that they need one more arm to do all the work, but now, that may be about to come true. Brain-controlled prostheses have long been developed for people with disabilities, but its next level will be to improve the workability of ordinary people.

Researchers at the Advanced Telecommunications Research Institute International (Advanced Telecommunications Research Institute International) have demonstrated that healthy people can also use robotic arms to "multitask" more effectively. .

The experiment uses the brain to control a robot arm while they still use their hands to do other things.

According to ZDNet, in the article published in Science Robotics, the researchers described an experiment: for healthy people to use the brain to control a robot arm while they still use their hands to do other things.

This experiment can erase the boundaries between people and machines as well as provide an overview of how the capabilities of machines can help people in real life. Currently, cyborgs have existed around us - for example, color-blind people have implanted antennas into their brains to distinguish colors, or biohacker (the term for self-implanters). suffer from technology into the body) embed RFID, NFC chips into their hands to open doors, make payments, or store personal data. We can now add a third arm to the list of ways to integrate technology with exotic but particularly effective biology.

In the experiment, the participants will have an electrode-mounted hat and sit in a chair with a robot arm like a human hand on the side. The purpose of the robot arm user will be decoded through brain waves, and the fake arm will be programmed to grab a bottle.

The robotic arm is positioned at shoulder height and wearing normal clothes, because previous studies have shown that the console of the brain and the machine (eg brain-controlled robots) will work. Better if users can feel robots as part of their biological body.

With this setup, the study participants will control the robotic arm by imagining it grabbing the bottle, while at the same time, they use their hands to balance the ball on a plate. table.

The interesting thing is that the results are divided into two separate groups, one team doing well and one team doing worse. Of the 15 participants, 8 succeeded in most of the trials (up to 85%), while the remaining 7 were only able to complete the job in 52% of the attempts.

Researchers believe that the difference between good multitaskers and less experienced people may be due to differences in the natural instincts of volunteers, not the console and the brain. .

However, this is still a small test group (with four women and one left-handed person) so it is impossible to conclude why some good people are multitasking and others are not, but the houses Research suggests that there is an explanation for that: some people have a natural instinct for better hand-eye coordination than others.
