During the poster session, I met a very nice fellow by the name of Peter Krčah, who had a poster and some videos displaying his work, which is an elaboration of work done by Karl Sims back in 1994.
The work involves evolving the morphologies of artificial creatures along with neural networks that control locomotive behaviors such as walking and swimming. Peter's website is here.
Here's a video demonstrating some of his evolved individuals:
In turn, this sparked some ideas that I've been working through relating to encoding and evolving 3D morphologies. I think it's cool work, but I definitely think it can be refined into more powerful and sophisticated representations. The creatures move in a way that evokes biological movement, but their morphologies are still very blocky and artificial.
Anyway, go have a look around Peter's site. It's fun stuff.
