Thanks for the information. We started with the mathematical approach, but
this seems to be extremely complex and not too useful for a reliable design
with LEGO-Technic and the RCX. Solving that kind of differential equations
in real time is perhaps impossible with the RCX.
Instead we think working upon a fuzzy self-learning algorithm, but we don't
know yet how.
On the technical side some people tried the challenge with light-sensors and
rotation-sensors. The rotation-sensor has a rather disappointing resolution
for these purpose, where we have to measure very small angles precisely.
Our KMZ-51 magnetic field sensor (which we used as a compass on
http://www.convict.lu/Jeunes/RoboticsIntro.htm ) may be used for detecting
deviations from the vertical. It is very sensitive. But before use we must
check the sensor-response to the vertical earth-magnetic-field. This will be
our next test-unit.
Of course we need some help this time.

| Hello Claude, What about using this sensor to measure field generated by a small magnet fixed on the pendulum ? But perhaps the Kmz51 is too sensitive and would saturate ? Philo (...) (23 years ago, 20-Oct-01, to lugnet.robotics.rcx)
