A paralyzed patient equipped with an implanted brain chip has been
able to use a robotic arm to reach for and pick up a bottle of coffee,
bring it close enough to her face so she could drink from a straw, and
then place the bottle back on the table.
The quadriplegic patient was outfitted with an electronic brain
implant that can drive a robotic arm to reach and grasp objects (see video). A study published today in the journal Nature shows
that people with the brain chips can use the devices to perform complex
three-dimensional tasks that could be helpful in daily life.
