David Mold's excellent robot. Source code included. I'm not sure if it was the first robot with PatternMatching, but David certainly succeeded in explaining the basic mechanism and prove its usefulness. Check out MogBot home page.
Many bots use MogBot style PatternMatching. Including:
- Marshmallow - source code and discussion on Marshmallow/PatternMatcher
- SpareParts - how could I leave out something? :-P He's completely open source, so feel free to take a look.
Please add robots to the list.
