Team Hassenplug made a connect four LEGO bot, it’s takes a very steady hand…! – “This is a robot that was designed and built to play Connect-Four in a contest against other robots, which it was lucky enough to win. During the event, it didn’t lose any games (once I remembered to plug the AC into the RCXs). The name comes from the method it uses for checking the board. Six axles are pushed into the six vertical holes, contacting any chips which are in the board. This process is repeated seven times (once for each column).” [via] – Link.
