News from the postman. We received the piece we had ordered on ebay and moved immediately to action, the construction of Chasso version 4.

We are confident this will be the final version (or be near it). This version uses one motor for locomotion, one for lowering a base and another motor for doing the rotation we want.
This version is based on a version created on a book Extreme NXT: Extending the LEGO MINDSTORMS NXT to the Next Level, 2nd edition, by Michael Gasperi and Philippe E. Hurbain (link here), which was built for an Odometer, exactly what we are doing.
We then need some adaptions for carrying bumpers, ultrasonic sensor, compass and web camera.
A big thanks to Nelson Russa who let us is Lego RCX so that we could have enough lego pieces to construct what we needed.
Next weekend we will do the tests and get back to blog with the results.
