I want to find out, how accurate my teach mode servo arm is.
I thought of adding a felt-pen to the learning arm and guide the teacher arm along a geometric pattern.
The pen would draw a (mirrored) copy of the pattern.
But it would be much more fun to redraw a famous cartoon hero (eg. Snoopy, Mickey, or Bugs Bunny) and post the results here.
So here’s the challenge: Make your bot draw a copy of well known figure. Use ‘line follower’ sensors to mimik a scanner or (Pixy-) Camera or whatever you like.
Who’s done it before?
