Only the Ozobot Evo app.

The Ozobot Evo app is the companion app that pairs Evo with your smartphone or tablet.

The Ozobot and OzoGroove apps are for use with Bit on tablets. Bit does not connect with your tablet, but can read lines and color codes on the tablet’s screen.

Always play with Evo indoors on a clean, flat surface.

Liquids, dirt, and other contaminants can permanently damage your robot.

Evo is equipped with a strong polycarbonate shell and can withstand occasional drops.

Evo and Color Codes

OzoCodes are color codes you draw with markers that tell Evo what to do.

Learn to draw OzoCodes here.
Get Drawing Tips (PDF) here
Get the OzoCode Reference Chart (PDF) here.

Lines and OzoCodes 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 OzoCodes. Evo’s optical sensors will not function outdoors in bright sunlight.

Get more OzoCode markers here.

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 OzoCodes, 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.

Video: Calibrate Evo on Paper


Drawing Lines and OzoCodes

Only draw OzoCodes 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.
