Here are some step-by-step instructions for how to build the Doodle Bot that Mark makes in class. You can use this guide on its own, or you can follow along with Mark as you watch the video, using this guide to help fill in the details along the way!
Mark uses the following items to build his Doodle Bot. Don’t worry if you don’t have exactly the same materials as Mark—you can probably make your Doodle Bot out of items you have lying around!
(1) Choose 4 marker colors you think would look good together.
(2) Tape 3 of your markers to the outside of the cup, so that they extend an inch or two beyond the lip of the cup.
These will be the “legs” of your Doodle Bot. There will be 4 total, so leave room for the last one!
(3) Align the fourth marker to the plane created by the other 3 to ensure that your Doodle Bot will be level.
Then, tape that one on too. You should now have 4 markers, evenly spaced around the outside of your cup, which your cup can stand on.
