Tries to write 'LMR'
Time to build: 
3 hours

While coding new interactivity into this robot, and trying to achieve more control on the way it moves, I though it would be cool to see what happens if I mount one little servo to hold a pen, and tell him to write 'LMR'.

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 is not centered on the chassis.. the correct position for the pen would be exactly between the wheels..

If the pen was in the chassis center the result would be accurate!! I still can´t keep 90º angles everytime I move on to the next letter!  :)

At the same time it was nice to see this little creature drawing lines on its own  :)

I love the little victory roll at the end. Mine just sort of struts off stage!

Hey - it's working now.

That is just a brilliant effect! How on earth did you do that? :D

Just need to get the pen to write "LMR".

Brilliant tracing/tracking your robot in that video. How on earth... what he said!?

In this case it is frame by frame editing.

I took the red LEd as reference, and every single frame I place one colored dot over the LED.

It was done in Autodesk Combustion, you can do the same in Adobe After Effects of in Flash.   :)

Nice work!

(Though I'd also hoped you could tip us of some tracking sw, would be quite handy! :)

But nice!!

Yes!!  The sw´s that I mention (except Flash) they all do tracking automatically, but it is kinda tricky..   

In this case I´ve made it manually  :)

That sounds like hard work! Good job though. You almost proved that your bot can actually write.

;-)

I was really hoping you had software to do the tracing.
