Ozobot Color Coding Doesn't Work Properly

Here are some things to try if your Ozobot robot ignores the color coded instructions:
1. Make sure your lines are the right size.
   In order to make the Ozobot recognize the line,
   it should be about 5 mm wide.
2. Make sure your lines are consistent.
   If the line gets wider or thinner,
   Ozobot may loose the line and stop its motion.
3. Make sure your turns are curved gracefully.
    If the continuation of the line is in parallel and too close,
    the Ozobot robot may see it as the same line
    and won't be able to make the turn.
4. Make sure you don't have sharp curves.
5. Make sure your color coded sequence is positioned correctly.
    The sequence should be surrounded by
    Black lines longer than 2 cm in length.
    All colored components of the sequence should be
    the same size and length,
    without any white space in between or overlapping colors.
6. Make sure the coded sequence colors you are using are not too dark or light.
7. Make sure the sequence is at least 5mm wide
    and no longer than 6 mm in length for a single color.
8. Make sure your color coded sequence is well seen by the robot.
   Keep codes on straight lines away from the corners, 
   away from intersections,
   and at least 2.5 cm apart from each other.
9. Make sure you are using the correct markers 
10. Make sure your robot is fully charged.
     If Ozobot blinks red, then the battery needs to be charged.
11. Make sure your Ozobot robot is calibrated.
12. Make sure your Ozobot robot is clean to allow his sensors a good visibility.

What Markers Should I Use To Color Code Ozobot Robot

Many lessons require black, red, light blue, and light green markers.
It is recommended to use Ozobot markers to ensure that your robot reads the colors reliably.
Crayons, dry erase markers colored pencils, water colors and highlighters should not be used with Ozobot.
You can also use Sharpie wide chisel tips (in pastel colors for blue and green) or Crayola classic markers.
If you are using permanent markers, place an extra sheet of paper underneath to avoid marks on the table surface.
Please note that Ozobot markers should only be used when drawing lines and OzoCodes.
If the markers are used to color in pictures and images then the ink will not last as long.
