Re: Manual Velocity PID, anyone successful?

This is exceptional when going up ramps and stuff, if your bot trys to turn sideways on the way up, and your driver is pushing the joystick straight, the PID loop will keep it going straight no matter what!
This is exactly what our software team is working on. They've asked me to look around for some sample PID code using the gyro. Our gyro is working (as is the camera), but they haven't integrated everything yet.

Anyone feel like helping point us to a sample?
