This is my friend: Richard T. Vaughan's homepage
I haven't seen him for a while. He does very clever things with Robots or as he puts it:
My research concerns the mechanisms of intelligent behaviour in populations of machines. I am particularly interested in devices that are small, fast, simple and cheap.
My research interests include:
Intelligent networks
Animal Robotics
Tools for network control and simulation of large populations
Minimalist robotics, micro-robots and micro air vehicles
Highly autonomous robots and software agents
Artificial life
Associations
Member, IEEE Robotics and Automation Society.
Associate Member, The Free Software Foundation.
Hope to see him soon.
