A Worm's Mind In a Lego Body

mikejuk writes The nematode worm Caenorhabditis elegans (C. elegans) is tiny and only has 302 neurons. These have been completely mapped, and one of the founders of the OpenWorm project, Timothy Busbice, has taken the connectome and implemented an object oriented neuron program. The neurons communicate by sending UDP packets across the network. The software works with sensors and effectors provided by a simple LEGO robot. The sensors are sampled every 100ms. For example, the sonar sensor on the robot is wired as the worm's nose. If anything comes within 20cm of the 'nose' then UDP packets are sent to the sensory neurons in the network. The motor neurons are wired up to the left and right motors of the robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. The key point is that there was no programming or learning involved to create the behaviors. The connectome of the worm was mapped and implemented as a software system and the behaviors emerge. Is the robot a C. elegans in a different body or is it something quite new? Is it alive? These are questions for philosophers, but it does suggest that the ghost in the machine is just the machine. The important question is does it scale?

Put the glasses on, stupid.

Initially read it as "A Woman's Mind in a Lego Body". Wasn't quite sure where to go from there so I squinted a little bit. Fortunately Timothy saved me from having to explain to my wife just what 'that stupid Slashdot article" is about.

ah but then it begins to eat harvesters.

If you want to scale this worm's mind in a lego body, try MongoDB. It's web scale and has sharding. It just works.

Try Duplo.

Cylon worms ?

So the creator of Battlestar Galactica dies, and we learn that people are building LEGO cylon worms. Interesting...

Scaling

Imagine a beowulf cluster of those.

More importantly, the Bible tells those who believe in it that nothing is unknowable: Genesis 11:6

>The Lord said, “If as one people speaking the same language
>they have begun to do this, then nothing they plan to do
>will be impossible for them.

So it's blasphemous for Christians (or Jews or Muslims) to say that humanity can't understand such things (or anything).
