After a few failed attempts, I’ve finally managed to build a reasonably reliable Connect-4 playing NXT Robot. It talks to the PC over Bluetooth to do the thinking because it uses a minmax algorithm that needs function recursion which is not supported by NXC. And since I’m not smart enough to write my own, I had to find one on the web, credit and thanks to Keith Pomakis.

I deliberately haven’t (yet) looked at the other ones that are out there because I wanted the challenge of creating my own. I’m fairly pleased with the result.

Very nice.

Keith's code is very good. I used it when I made an RCX robot a few years back. I found it easily beats most players when set to look ahead four moves (two for you, two for opponent)

I like the way it wiggles to drop the chips in.

NIce work Andy. Great use of the NXTCAM.
