ROBOTIC AUTH3R+ is the work of 10 hours, 4 hours to build, 6 hours to program. It was a huge challenge. Because of the immense size of the program, I will post it as a second robot later. Any way, I programmed it to write 'lukeshev.' Pic 2 is what I expected, Pic 3 is what I got. (I had to retouch it a little so that you could see it.) Pic 4 is the writing utensil that I chose -- a green BIC pen. -- For a complete description of my robot, please go to 'additional info'.
P.S. Do you like the personalized username I build out of lego in the background? (Pic 5)
