Farrusco tries to write ‘LMR’

While coding new interactivity into this robot and trying to achieve better control on the way it moved, I thought it would be cool to see what happened if I mounted one little servo to hold a pen and asked it to write ‘LMR’ – the initials of the website:  www.letsmakerobots.com

The idea came from this challenge… and I thought I could give it a shot.

The result was far from what I expected.
The pen was not centered on the chassis.. the correct position for the pen should be exactly between the wheels..
At the same time, it was nice to see this little creature drawing lines on its own  :)

This is what could be drawn if the pen was centered.
I have a lot of difficulty keeping right angles everytime I move on to the next letter..  :)
