Can robots teach us anything about Culture?
Festival of Ideas, 22 May 2011, Bristol
Alan FT Winfield http://alanwinfield.blogspot.com/Bristol Robotics Lab http://www.brl.ac.uk/
A Big Question: How do we have Culture?
We are interested in the processes and mechanisms by which culture emerges…
?
by building a working model of cultural evolution…
with robots
artificial culture lab
What is culture anyway?
The way we do things around here
The Memetic theory of cultural evolution
Meme (n) A unit of cultural transmission
Transmitted by social learning and subject to• variation, • selection and• inheritance
Learning by Imitation
We focus on social learning by imitation
The imitation of movement*
*in the Bristol part of the project which I describe in this talk

Imitation is hard to do
Imitate the last thing you seeAnimation of recorded robot moves:
…and the dance quickly degenerates
Ok, try a different strategy

Open-ended memetic evolution
And we see the emergence of a new meme species
Making sense of it all
A family tree of meme evolution.Solid lines and red memes are high-fidelity copies of parent memes
Have we learned anything about (robot) culture?
