Ideas for RobotC articles

//Moved to Here

Hi

On our website we are making a page with lots of tips for building/programming/competing with vex robotics.

I want to write a few short articles on how to do certain things with RobotC
I have already written an article titled “Line Following with RobotC” (Not finished)

Has anybody got any ideas on other subjects you would like me to write about?

Thanks

I wrote an article for “ROBOT” magazine on a very fast VEX line following robot that was published in 2009. There’s a video on YouTube – search for “VEX line following robotc” to access it. It used a line following sensor array from Pololu and a PID algorithm. It’s several times faster than a basic line following robot.
