Does anyone have some RCX code to make a simple differential drive (2
independent motor/wheel combinations) with 2 rotation sensors drive straight.
I'm sure it's been done many, many times before and I don't want to reinvent the
wheel here. NQC or even pseudocode is O.K.
Thanks,
John

| (...) Just one rotation sensor. The differential gives you the difference (hence the name) of the two sides. If it's zero, you're driving straight. A positive rotation means you are turning one way, and negative is the other. It's not pseudocode, (...) (18 years ago, 31-Dec-06, to lugnet.robotics)
