My GIANT wall painting robot

Summary by Krater

The creator builds a custom CNC wall-painting robot using a gantry system and optical motion tracking to paint large-scale halftoned portraits on walls using CMYK colors.

Answers: How do you build a robot that paints portraits on walls?

• CNC wall painting robot
• Halftone printing on walls
• CMYK color theory in robotics
• Motion tracking for robots

What it concludes

• Traditional ink jet printers produce 1,000 dots per linear inch, making a 50-foot wall take 65,000 years to print.
• Using CMYK and halftone convolution allows a robot to accurately recreate full-color images on a wall using discrete dots of paint.
• Optical tracking cameras positioned on the robot eliminate mechanical inaccuracies by dynamically correcting the spray head position.
