After more than half a year from the MadridBot competition, I’ve decided to rescue the documentation and pictures of the robot that we built for a line-following (speed) competition.
It’s basically a 1:28 scale RC car hacked with a servo for direction and an home-made arduino based board. In the front there can be seen 5 x CNY70 line sensors (IR reflection), shielded from light and crashes with foam. The rest of the car is described in the pdf below.
