We just started studying the inverted pendulum problem in order to solve it with the RCX and lejos or legos or PBForth. We are not decided yet. At first sight this seems a rather serious problem.

FYI - I just noticed in the component specs from Sharp that the GP2D12 (and GP2D15 for that matter) have a built-in voltage regulator. See (URL) is an external regulator a necessary precaution? Just curious... - Gareth (24 years ago, 9-Oct-01, to lugnet.robotics.rcx)
