Robot Controlled By Rat Brain 170
kkleiner writes "Kevin Warwick, once a cyborg and still a researcher in cybernetics at the University of Reading, has been working on creating biological neural networks that can control machines. He and his team have taken the brain cells from rats, cultured them, and used them as the guidance control circuit for simple wheeled robots. Electrical impulses from the bot enter the batch of neurons, and responses from the cells are turned into commands for the device. The cells can form new connections, making the system a true learning machine."

If it uses living cells from a rat brain, then it's not really a machine.

What doesn't seem too clear after listening to the videos is why the rat's cells wouldn't want to crash the robot it's controlling, into the wall. Did the scientists program that in (perhaps wall crashes give the cells some kind of negative electrical stimulation), or did the cells have a mind of its own on that front?
The difference is subtle because it means we have either a 'mere' replacement for computer chips, or potentially much more - a sentient clump of cells which want the 'best' for the robot it's controlling.

Mainly the neuron control helps the robot to avoid walls.
So there must be messaging back into the rat. So the robot is to some extent controlling the rat brain.

Say I have a terminal illness. It some of my brain cells can be kept alive, and given a robot body to motor around in, maybe its worth a go.

What about knowledge or behaviour inherent to a species? It's not like the rat brain started from zero like a "start from scratch" computer-learning program would.
