Someplace (a book or web page) I saw a way to control the speed of a
mindstorm motor. Not just changing the power, but the speed.
If I remember right, they created an NQC task that did its own PWM on
the motor output. I spent a frustrating evening trying to do this and got
nowhere fast.
What I would like to be able to do is to make graceful turns of various
radii by adjusting the speeds of the drive motors. Since the bot is only
gently loaded, the power settings have little or no effect on the bot.
Any pointers or ideas would be welcome.
