Scientists Bring The Sense Of Touch To A Robotic Arm

A robotic arm with a sense of touch has allowed a man who is paralyzed to quickly perform tasks like pouring water from one cup into another.

The robotic arm provides tactile feedback directly to the man's brain as he uses his thoughts to control the device, a team reports [DOI: 10.1126/science.abd0380] [DX] Thursday in the journal Science.

Previous versions of the arm required the participant, Nathan Copeland, to guide the arm using vision alone.

"When I only had visual feedback, I could see that the hand had touched the object," Copeland says. "But sometimes I would go to pick it up and it would fall out."

A typical grasping task also took Copeland about 20 seconds to complete. "With sensory feedback he was able to complete it in 10," says Jennifer Collinger, an associate professor in the department of physical medicine and rehabilitation at the University of Pittsburgh.

    Impossible: it could only be a pre April 14 dupe, or a post-Soypocalypse dupe, and this story is dated May 20. There have been only 8 stories since the restart, and none of them are about touchy-feely prosthetics. So no.

      MartyB is getting married! I am so happy for him. Gushing with joy, or, something.

      Well, it could have been posted in the lost period. I'm not sure if that would technically make it a dupe.

      If you define a dupe as a story posted twice, then it would be. If you define a dupe as a story that already exists on the server at time of posting, it wouldn't be.
