…from BBC news (http://news.bbc.co.uk/2/hi/science/nature/3096973.stm).
Gave me a vaguely disconcerting feeling (shades of sci-fi gone awry).
Interesting though.

"Rat-brained robot does distant art
By Lakshmi Sandhana


Meet the latest spaced out modern artist - a picture-drawing robot arm in
Australia whose brain sits in a petri dish in the US.

The robot arm is in Perth…



Working from their university labs in two different corners of the world,
American and Australian researchers have created what they call a new class
of creative beings: "the semi-living artist".

Gripping three coloured markers positioned above a white canvas, a robotic
arm churns out drawings akin to that of a three-year-old. Its guidance comes
from around 50,000 rat neurons in a petri dish 19,000 kilometres away.

The "brain" lives at Dr Steve Potter's lab at Georgia's Institute of
Technology, Atlanta, while the "body" is located at Guy Ben-Ary's lab at the
University of Western Australia, Perth.

Webcam stimulation

The two ends communicate with each other in real-time through the internet.

The project represents the team's effort to create a semi-living entity that
learns like the living brains in people and animals do, adapting and
expressing itself through art.


…but the brain is in Atlanta

"We are looking at future scenarios where geography won't matter," said Mr
Ben-Ary. "The brain of the semi-living could be anywhere in the world, while
the body (machine) will interface and be fed off it," he told BBC News
Online.

"It really makes you think about the future possibilities, and realise that
the sci-fi vision of movies like Cold Lazarus can turn into reality in the
future."

Termed Meart (Multi-Electrode Array Art), the cells are connected via 64
two-way electrodes to a computer and are stimulated by information; in this
case transmitting scaled-down images of visitors in its vicinity, captured
with a webcam.

Learn a little

The computer translates any resulting neural activity into robotic arm
movement. By closing the loop, the researchers hope that the rat culture
will learn something about itself and its environment.

"I would not classify [the cells] as 'an intelligence', though we hope to
find ways to allow them to learn and become at least a little intelligent."
said Dr Potter.


The drawings are becoming less chaotic

"I look forward to seeing something everyone would call 'learning', but so
far, we only have evidence that the system is developing and adapting, such
as becoming more controlled - less chaotic over time," he added

Dr Potter hopes the venture will provide valuable insights into how learning
occurs at a cellular level.

The latest initiative is a development of the SymbioticA Fish And Chips
project, in which the artist-scientists grew fish neurons over silicon chips
to control a robotic arm that produced drawings and music."
