Washable Color Code Markers, for Ozobot
Evo and Color Codes
Color Codes are commands you draw with markers that tell Evo what to do.

Lines and Color Codes for Evo should be drawn on plain white paper with black, blue, red, and green markers.
Use Evo indoors on a clean, flat surface. Evo relies on optical sensors to read Color Codes. Evo’s optical sensors will not function outdoors in bright sunlight.
In addition to washable Ozobot markers, you can use classic Crayola markers or Sharpie wide chisel tips. You’ll need black, blue, red, and green. For Sharpie markers, use the pastel shades of blue and green.
You cannot use dry erase markers with Ozobots.
Calibration
If Evo isn’t reading Color Codes, you may need to calibrate. Calibration adjusts Evo’s optical sensors to the surface and light environment. Calibrate Evo whenever you change surfaces (paper to screen) or lighting conditions.

Drawing Lines and Color Codes
Only draw Color Codes on black lines. Your lines and codes should be no wider than an Ozobot marker’s chisel tip (approx. 0.25 in. or 6 mm).
Don’t make Color Codes too dark. If you make the colors too dark with multiple passes, blue or green will look like black to Evo.
