Robotic Arm Controlled By Monkey Thoughts

Posted by Zonk on from the next-step-is-cyber-monkeys dept.

mallumax writes "The BBC reports that Pittsburgh University scientists have succeeded in creating a robotic arm, controlled by probes inserted into the brain of monkeys. The probes interpret signals from individual nerve cells in the motor cortex. Monkeys were able to grasp and hold food with the robotic arm. Since the number of nerve signals for even small movements is huge the scientists used an averaging algorithm to obtain the movement signals."

    Wouldn't this also be a sign that monkeys are capable of fairly sophisticated tool use?

      That's not the impression I got. It seems more like the monkey was moving the tool as if it were it's own limb, i.e. the moneky tried to move its hand and the tool moved instead. If this is the case, all it shows is that monkeys can control their own limbs.

      I would think that there is plenty of non-robotic evidence that monkeys use and make simple tools, are skilled and knowledgable in their use and pass tool knowledge from individual to individual already in the wild. Monkeys have been trained to operate tools and devices before this, both in and out of laboratory settings. I wouldn't consider this a breakthrough or in any way revealing about monkeys, I would consider it more of a robotic/hapic/man-machine interface breakthrough.

    The following is an acceptable question to ask:
    "Should we really be attaching electronics to monkey neurons?"

    1. Re:Acceptable question now... by Richie1984 · · Score: 4, Insightful

      That raises the question "is animal reseach acceptable if it benefits a larger number of humans?", which is a debate beyond the scope of this article, in my opinion. There's no indication that any animals were harmed in the process, and there's no mention whether there is any lasting damage, or if the proceedure is reversable. But, if I were going to use the technology, I personally would like the answers to those questions beforehand.
