My brother's getting some experience wielding a soldering iron, and has a growing pile of transistors, resistors, eyes of newt, and other arcane components. Mentioned getting some toy robots to build, and it kind of fits in with something I saw this morning:
It was a show talking about ants and other social insects working without a distinct leader, based on simple programmed rules and the patterns that emerge from having several members following them, often without communication. They went on to an example of robots sorting out black and white pucks based on a handful of rules. I recalled an example from much earlier involving smaller robots sorting wooden pegs.
So, anyone know some robot kit to build critters like that? I'd like to have something where I can rearrange the rules to see what emerges from different rules. Haven't talked about it with my brother, but seeing some recommendations for robot kits might be interesting anyway.
