LEGO Spirit | 2003

Well... It is a very old model, I think that it is one of my firsts trade show model. It was developed to participate in the launch of FLL (First LEGO League) 2003 in Brazil.

The robot works with 2 RCXs, 7 motors, 1 micro motor and a pneumatic system. It has a very interesting transmission system at the front, where it has a worn to reduce and change the direction of the movement.

But I think that the most impressive is that it is still working, of course I did some maintenance, but it preserves the same functionality of the first presentation.
