Spirograph Automaton made with LEGO Mindstorms EV3

This Spirograph Automaton is a LEGO drawing machine based on the the popular toy and the ideas of PG52. This version extends previous designs by using LEGO Mindstorms EV3. The Spirograph Automaton knows when the pattern is complete and lifts the pen at the right time. You no longer have to observe the machine to stop it when the drawing is complete. The gears are optimized to give fast results so that the children do not have to wait too long. I also build a coin detector that triggers the Spirograph Automaton.

The building instructions are available for very affordable price ($0.99). Please notice that the instructions do not include the three Mindsensors’ GlideWheel-AS sensors. They are not part of the LDD library. And neither is the part 14720 (Technic, Liftarm 3 X 5 Perpendicular H-Shape Thick) of which you will need two. You will also need four rubber bands, may it be from LEGO or otherwise. You can also consider using the Technic Changeover Plate (6631) for a better gear shifting experience. The complete parts list is available at ReRrickable.

The required software is available here. You need to run the program “calibrate” before running the program “draw”. Otherwise you will get a file reading error.

I recently started to document my family’s history. This genealogy expedition became urgent since my grandparent might not life much longer. I encountered several practical and conceptual problems that are far from being trivial and I would like to invite you to work with me on them, possibly in the format of a (student) project.
