Inverted Pendulum
Start Date: 2/26/01
End Date: 3/12/01

Description:
A classic control problem: design a robot that balanaces a pendulum upside
down in a 2-D plane (imagine balancing a broom on your open palm). This is
an inherently unstable system whick makes it interesting.

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

(...) OK, now that I've figured out what the pendulum base looks like, I can see the advantage of the rotating base, namely that we eliminate the need for detecting the end of the range of motion! Thanks to all who helped in my quest for (...) (24 years ago, 26-Feb-01, to lugnet.robotics)
