Line following racers

[Tim] sent in these quick little line following bots (translated). They were sent as participants in cosmobot, but due to an unfortunate dropbox mishap, they didn’t have updated firmware. They placed fifth and ninth place. As you can see in the video above, they are quite speedy. You can get the schematics and code on their project page (translated). They are hoping to make improvements to place better with the same bots next year.
