Making a robot to carve photos into pumpkins

A video on YouTube. In Science & Engineering, a Krater category.

Summary by Krater

The creator modifies his automated haircut robot into a custom CNC pumpkin-carving machine, testing various software approaches like Mercator projection to carve different shapes, patterns, and faces into pumpkins.

From the video

Answers: How do you build a CNC machine to carve pumpkins?

CNC pumpkin carving
Mercator projection math for 3D mapping
Plasma cutting sheet metal
Tormach 1100MX CNC mill
Tormach 1300PL plasma cutter

What it concludes

Mercator projection successfully maps 2D images onto a sphere for pumpkin carving.
Tormach 1300PL plasma cutter and Tormach 1100MX CNC mill provide the necessary precision for custom robotic builds.
Lithophane engraving allows for subtle depth and grayscale detailing on pumpkins compared to basic chunk cutting.
