Hi jrbums, I've modified the robot. Now it's much more robust. It can walk forward and backward. There's a video newly uploaded in step 9. As the robot doesn't have encoder of the wheels, it can't go straight line. I'll improve it in future by adding some photo interrupters.

Very cool! But I don't know if it's allowed by law, that attach external components outside a car.

It works. Thanks.
Thanks, it works! I added the html tag, then it works! The source code is below:<html>Scrollbox: <textarea style="width: 600px; height: 300px;" rows="20" readonly="readonly" name="code" cols="75">pPart = pidValue.proportionalValue * angleErrorNew;iPart += pidValue.integralValue * angleErrorNew; dPart = pidValue.derivativelValue * (angleErrorNew - angleErrorOld);</textarea></html>Thanks a lot! Problem solved.
Thanks for the suggestions. The idea is cool, but it's much more challenging. I'll focus on the two wheel robot and improve it continuously, such as use a larger wheel to increase stability, replace breadboard with a homemade PCB, add encoders for the motors.
Currently it's still not robust enough with moving back and forth. I'm trying to optimize the system. As soon as the robot is stable, I'll upload a video.
Thanks. There are many improvements to be done. Hopefully I will update this instructable or publish a new one.
