@m0rjc You could use a rotary encoder and a normal pendulum, but would have to beware of that oscillating in its own right. Maybe you could filter those oscillations out and use it as a long term reference, but its movement could interfere.
Looks a great project though!

We did similar at university only it wasn't free standing. The pendulum was mounted to a trolley which moved on a track with motor driving its position. In that case it was easy to get the position using a rotary encoder on the pivot (or potentiometer but that adds friction). It was also easy to use a rotary encoder to sense the position of the trolley which gave the interesting problem of controlling that position while keeping the pendulum balanced. Then we tried double pendulum.

Hi, what is a compass, I search a lot on internet but I don't find anything pertinent.
The only models that I find indicates north I don'tt think this is it.
Can you tell me a reference please ?
-
recommend a compass!? a compass doesn't have enough resolution for a stable system, look at ur bot jerking around. Best is gyro with an accelerometer to compensate for gyro drift!

Check what we're doing with Arduino, NXT & Etoys. Have fun! :) /watch?v=l_IYlDbBlEs

good job man, cool stuff!

Not first... i have seen one before

Fckin awesome

Does this use an accelerometer ?

I read somewhere that it is possible to read the sensor data of the wiimote nunchuck through i2c. Would it be possible to use the integrated accelerometer and gyroscope for this project?

@MAcDaTHo I didn't know the nunchuck had a gyroscope.
For this kind of project I do NOT recommend to use accelerometers or gyroscopes.
You should use a compass, that provides the angle (instead of angular velocity or angular acceleration). This makes it easier... if you build a math model you'll see why.
Bye!

can i do such a thing with Arduino Duemilanove ATmega328?
evermanito 2 years ago
Yes, it's the same thing :)

It looks like I can't post link.
Source code and details of ARDUWAY are available on the Arduino forum and on Sourceforge.
Google the following: "arduway arduino forum"
for source code: "sourceforge arduino2lego"

I'm sorry I'm having a few problems commenting my own video because YouTube for some reason is censoring my comments...
