Nature and Machine

A roboticist- known to the public as Dr. Faust- created the first ever robot powered entirely by nature and luck.

Her robot is situated outside at all times, leading to nearby Shamrocks and butterflies to grow and land on the robot. Because the robot is powered by luck absorbed from the tank in its head, the excess shamrocks growing on its body gave it the ability to paint luck into any object. Today, Dr, Faust gave it a bunch of gold coins, and we can see that- even as lucky as it is- even the robot spilled paint all over its fingers.
