Ants Used For Mind-Controlled Robotic Limbs
mr sanjeev writes "Australian researchers are reducing the divide between science fiction and science reality by bringing the development of mind-controlled robotic limbs a few steps closer. Even the most fertile science fiction imagination might not see a link between the behavior of ant colonies and the development of lifelike robotic limbs, but that is the straightforward mathematical reality of research underway at the University of Technology, Sydney. The technology mimics the myoelectric signals used by the central nervous system (CNS) to control muscle activity. Artificial intelligence researchers have long used the complex interactions between ants to construct a pattern recognition formula to identify bioelectric signals. PhD student Rami Khushaba said 'swarm-intelligence' allows scientists to understand the body's electrical signals and use the knowledge to create a robotic prosthetic device that can be operated by human thought."
I agree completely. Trying to calibrate to the specific signals from the human brain is solving the wrong problem. The most awesome capability that our brains have is the ability to adapt. Spend more time on processing the signals in the arm-end for execution, and in sending tactile feedback signals back. It might be nearly impossible for a person to use for a while, but once the brain figures it out and starts rerouting itself, it will seem perfectly natural.
An analogy: if you have a car, and you're trying to build a better road, you should focus on improving the surface of the road, not on a mechanism that reaches up to help push the car along. The "move the car" problem is sufficiently solved that your efforts will probably just get in the way.
