STEM Education Kits #17

Doodle Robot:

Principle: When the rocker rotates, it will always move the
bottom plate in the opposite direction, which will cause the
motor and the bottom plate to vibrate at a high frequency, and
the pen tip will also vibrate up and down. When the tip of the
pen leaves the paper, this curved vibration will cause the pen
tip to continue to move and achieve the purpose of graffiti.
