Self-reconfigurable modular robots
Here's a fascinating post on Engadget entititled "M-Tran self-reconfigurable modular robot", which mentions a new form of robot created in Japan that is actaully able too assemble and reconfigure itself using evolutionary genetic algorithms. This is a hint of the kind of flexibility that we will see in intelligent software agents in the coming years.
It doesn't sound like they have endowed the robot with the ability to seek out and interact with other reconfigurable robots, but give them time... "Legos of the world, unite!"
