Origins of the Roomba 1949

[David Baxter PhD]

Dr. Grey Walter was a neurologist, robotics pioneer, and a bit of a mad scientist. Living in Bristol, England in 1949, without the aid of modern day computer processors, he built reactive, autonomous robots that could wander about and avoid obstacles. Each robot had two simulated neurons, sufficient for them to display complex behavior. Significantly, Walter's tortoises represent the first real world demonstration of artificial life.

One of his other discoveries:

In the 1960s, Walter also went on to discover the contingent negative variation (CNV) effect whereby a negative spike of electrical activity appears in the brain half a second prior to a person being consciously aware of movements that he is about to make. Intriguingly, this effect brings into question the very notion of consciousness or free will, and should be considered as part of a person's overall reaction time to events.
