Drawing lines for Ozobot

The drawing rules from Ozobot’s official guides, with a separate column for Ari.

The line

5 mm thick (4.5 to 6 mm is okay), actual size

The same thickness throughout: the robot has trouble reading a line that alternates between narrow and wide.
Draw with the Ozobot marker, using the flat side of the tip.
Use white, non-glossy paper. No whiteboard markers, colored pencils, crayons, or highlighters.

Tip

First sketch the route lightly in pencil, then add the color codes, and finally draw over it with the black line.

Want to print your own route?

Print in color on white, non-glossy paper at 100% (actual size). Then measure one code cell: it should be 5 mm.

Space around the line

Rule	Bit+ and Evo	Ari
Distance between parallel lines (including in a U-turn)	≥ 25 mm	≥ 38 mm
White space on both sides of the line	± 12 mm	± 19 mm
Width of a turn	≥ 25 mm	≥ 38 mm
Distance between Color Codes	≥ 51 mm	≥ 51 mm
Distance from a code to a turn or intersection	≥ 25 mm	≥ 25 mm
Straight section after a Zigzag or Backwalk code	≥ 64 mm	≥ 76 mm

Different robots in the classroom? Use Ari's measurements so your route works for all three.

Corners and intersections

The ideal angle is 90°. The robot may not follow an acute angle properly, but a wide, rounded turn is fine.
An intersection has three arms (T) or four (plus), with straight, perpendicular lines. Never place it on a curve.
Without a direction code, the robot chooses a direction on its own at an intersection.

Color codes

Only on a straight section, never on a curve, corner, or intersection.
Cells measuring 5 × 5 mm, with no white space between them and no overlap.
Black before and after. Two-color codes go at the end of the line, with about 20 mm of white space after them.

How to use this poster

Hang the poster where students draw their routes.
Have them check their route against the measurements on the poster before testing it with the robot.
Working with Ari? Use the measurements in the Ari column: they also work for Bit+ and Evo.

Questions and answers

How thick should an Ozobot line be?

5 mm is ideal, 4.5 mm is the minimum, and 6 mm is the maximum. The line must be the same thickness throughout. The flat side of the Ozobot marker is exactly the right width.

Why does Ari need more space?

The Ozobot Ari guide specifies wider spacing: at least 38 mm between lines and at least 76 mm of straight line after a Zigzag or Backwalk code. Follow these measurements and your route will also work for Bit+ and Evo.

Where can a Color Code go?

Only on a straight section: at least 25 mm from a curve or intersection and at least 51 mm from the next code. Never on a curve, corner, or intersection.

What paper works best?

White, non-glossy printer paper. Colored paper, cardstock, and glossy or photo paper don’t work well.
