LEGO Mindstorms EV3 Comparison
2+
==============================
3+
4+
This project is meant to complement the comparison made in
5+
`The Difference Between LEGO MINDSTORMS EV3 Home Edition (#31313) and LEGO MINDSTORMS Education EV3 (#45544)`_,
6+
an article by `Laurens Valk`_.
7+
8+
There are two editions of LEGO Mindstorms, LEGO's Robotics Invention System (RIS),
9+
the EV3 Home Edition and the Education Edition. You may wonder what is the difference
10+
and which one is right for you. Reviews on Amazon will tell you that the Education
11+
set is meant for schools, with a more robust plastic packaging and shorter, in-class
12+
exercises to go through instead of full-blown projects to be exercised from start to
13+
end that fulfill you as a robot newbie with the Home Edition.
14+
15+
If you one day want to upgrade your set you'll be wondering if you can combine the
16+
two. The data elaborated in this project may help you with your decision on what
17+
pieces to buy.
18+
19+
Usage
20+
-----
21+
22+
``Lego-Mindstorms-Editions-Comparison.ods``, a LibreOffice Calc spread sheet, lists
23+
the pieces of all sets combined. Columns ``F`` and ``I`` tell you which pieces to
24+
buy if you have either Home Edition + Expansion Set or Education Edition + Expansion
25+
Set. You can filter the columns using the "Auto Filter" in the first row.
26+
27+
``lego-mindstorms-pieces.py`` is a Python3 script to generate the combined list of
28+
LEGO pieces from the three separate inventory lists. It takes three file names as
29+
an argument.
