Rich,
Am I completely thick or is the problem simpler than I'm imagining? Way
back when at the University of Waterloo, we designed a 2D inverted pendulum
balancer on a plotter bed. The pendulum rotated a sensor, and we had to
move the bed to keep it stable. You'd get bonus points for moving the bed
in 2 dimensions....
I just don't understand the statement "Build a robot that stabilizes the
inverted pendulum by rotating it" or the picture (which should be enclosed
in a <pre> tag to display properly.
Please clarify as I'm anxious to make this robot :-)
Cheers, Ralph Hempel
