Write anything anywhere with this LEGO plotter
This LEGO BOOST plotter robot lets you write text on any flat surface. You can build this LEGO BOOST robot with a single LEGO BOOST set #17101, plus any pen (felt tip pens work better). Since it drives on wheels, the workspace of this LEGO BOOST plotter is unlimited in the writing direction! The motors of the LEGO BOOST Move Hub are used to drive the wheels and to move the pen up and down. The LEGO BOOST External motor drives the pen on the vertical direction. I designed this robot back in August 2018, and I published by popular demand.
