Hat's off to you! W. Grey Walter was one of my inspirations growing up.
He's one of the reasons I majored in robotics in college. I hadn't even
considered trying to reproduce his machines with Legos, what a great idea.
However as you mention on your web site, it it very difficult to reproduce
his behaviors with Lego. It's one of the distinct advantages of using an
all analog system rather than a digital one like Lego. I would go so far as
to say, an analog robot is about the only way of creating truly interesting
behaviors.
Good job,
Doug Durham
