How to draw a perfect path?
Better results can be achieved when lines that are quarter of an inch in thickness are used. However, you can make use of markers for thickening the paths you draw through multiple strokes.
But, you will achieve better results with wide markers that are able to develop that perfect path.
How to draw intersections?
When you are drawing intersections, you will have to keep note of the fact that the color sensing robot will be randomly picking up a path if not specified by a color code.
It is also worth mentioning here that Ozobot will have problems in maneuvering in case intersections you have made have turns that are not of 90 degrees.
How to draw the color codes?
These codes refer to color sequences consisting of 2, 3 or 4 color dots that are made directly over a path in a row.
The color sensing robot continuously scan floor signs so as to detect these colors and react in right way.
