Marble Runs, Mechanisms and AI Judges

Fun for the whole family! Whether you’re 6 or 96, you can flex your creativity to build an awesome marble run. Start with simple ramps and traps, or follow our print-and-cut plans to make marble flippers, servo-activated starting gates and even train a full-fledged AI judge to impartially tell you the winner of each race! Scroll down for all the project plans.

We teamed up with Make Magazine’s Family Maker Camp to live stream 2 sessions to get you started. Tune in to see us demonstrate building the mechanisms, adding electronics to make them move and light up. The second video also shows you how to use your webcam to train an AI to activate a second relay race when enough marbles complete the first run.

Spinners

Add some spinning traps to your Marble Run to help stir things up a bit

Train an AI Judge

Use your webcam to train an AI judge to display the winning marble of each race!

Racing Mixer

In this easy-to-build module, you’ll create a peg board which can shuffle up marbles at the start of a race. Combine this with our Starting Gate template and find out who’s marble team is the fastest

Marble Lift

Using the power of elastics, propel your marbles to new heights.

Peg Board

A large add-on for your Marble Run! Design a Peg Board to mix things up a bit, and add elastic bands to help guide marbles down a certain path

Scoring Zone
