Hbot is a plotter designed by TODO for an art exhibition inspired by the works of the kinetic artists of 
 GRUPPO T.  The design and prototype of the hbot was inspired by Gialuca Pugliese who also advised me during the process particularly in the electronic part. The idea is for an Arduino sketch to drive the movement of a magnet to attract ferrofluid, drawing a beautiful composition on transparent paper.
