Spirograph using Lego Wedo 2.0

A Drawing machine / Spirograph created using Lego Wedo 2.0 kit. The Spirograph can be used to draw various different shapes. The shape and size of the spiral depends upon:

1. The relative speed of the rotation of paper and pen. We tried with different combinations like Fast paper rotation - Slow Pen, Fast Pen - Slow Paper etc.

2. Second factor is the length of Pen to paper and the supporting arm that connects the pen arm to rotator. Again, Experiment with different lengths of the arms using the holes in both the arms.

3. Third factor is the radius of rotator that rotates the arm. You can use a wheel or gear as a rotator for small radius or create one using bricks as shown in video.

4. Fourth factor is where the arm that carries the pen is connected. If it is connected to the rotator, you will get different results, if it is connected to the fixed axle, you will get different results.

Hope you enjoy it.
