MINDSTORMS NXT® portrayer robot

This robot draws portraits, elaborating photos and images.
The software on the PC is developed under MATLAB®, following the ideas of Claude Baumann and his students at http://www.restena.lu/convict/Jeunes/ultimate_stuff/Erik_s_xy_plotter/E_xy_plotter.htm (Erik’s XY plotter).

The hardware is LEGO MINDSTORMS NXT® and a soft tip pen.
Made by Daniele Benedettelli in 2008. More details at http://robotics.benedettelli.com

    o my :O
    This MUST be one of the most awesome robots around at this point of time!

  4. The zero position …
    The zero position is set at startup. two PID controllers run in parallel to control precisely the arm joints angles, using the built-in encoders.

  5. superb!

    amazing …

    amazing even the drawing looks like a real person, and not like a plotter.

    way to go!

    That’s very, very impressive, especially the programming.

    I like the hardware too. Does the arm work with the rotation sensors all the time, or are there also some mechanical reset points?

    oh… my… god… this is exactly like what happened in that book “The Invention of Hugo Cabret” (good book with lots of pictures and ridiculously little amount of text)
