Maqueen v4. Programming course with Maqueen

Hello,

I received maqueen v4.

1. About packaging and hardware
Good progress:
-now a small booklet is included.
- mounting M3 holes are marked - it's desirable to do so in online instruction as well
- pins for 2 servo provided - it would be better to mark which ports are used there as well (is it p17,18?)

2. Map of Patrol line

- iI received 2-rings map while in online documentation it's oval track (I do not complain, just mark a discrepancy)

- looks like the distance between sensors and size of line are the same (15mm?). I had an observation a few years ago, with my own model, that more optimal is having sensors a bit (2-3mm) wider than size of line


3. I've published a programming course with maqueen in Russian, for age 10-13, 12 academic hours (45min). and soon to start on continuation (more exactly. it's rather material for a teacher)
Should Dfrobot have an interest in English version of the course, we may discuss it.
