Build : Two Arms Plott3r
My first idea was to make a plotter like the model of Control Center set 8094 from '94 which is one of my favorite sets!
But I would like to make something more original.
So I remember seeing some DIY project of a plotter using two arms.
As you can see, mine uses the two large EV3 motors to control arms and the medium motor to up/down the pen.
This is a great project to study trigonometry and, to be honest, at this time I need to improve the software.
I'm particularly happy about the mechanism that's keeping the pen straight when arms fold/unfold.
I hope this design could inspire many of you! Olivier, The Brick Detective
