Monkeys Control Robot Arm With Their Thoughts

Two monkeys with tiny sensors in their brains have learned to control a mechanical arm with just their thoughts, using it to reach for and grab food and even to adjust for the size and stickiness of morsels when necessary, scientists reported on Wednesday....

The scientists used the computer to help the monkeys move the arm at first, essentially teaching them with biofeedback.

After several days, the monkeys needed no help....

The monkeys learned to hold the grip open on approaching the food, close it just enough to hold the food and gradually loosen the grip when feeding.

The animals were apparently freelancing, discovering new uses for the arm, showing “displays of embodiment that would never be seen in a virtual environment,” the researchers wrote.

Seriously, if you find yourself on the University of Pittsburgh campus, and you see a ragtag band of assassins from the year 2258 making their way towards the Neurobiology Dept., do not - repeat, do not - interfere with them.
