This project is meant to complement the comparison made in The Difference Between LEGO MINDSTORMS EV3 Home Edition (#31313) and LEGO MINDSTORMS Education EV3 (#45544), an article by Laurens Valk. There are two editions of LEGO Mindstorms, LEGO's Robotics Invention System (RIS), the EV3 Home Edition and the Education Edition. You may wonder what is the difference and which one is right for you. Reviews on Amazon will tell you that the Education set is meant for schools, with a more robust plastic packaging and shorter, in-class exercises to go through instead of full-blown projects to be exercised from start to end that fulfill you as a robot newbie with the Home Edition. If you one day want to upgrade your set you'll be wondering if you can combine theThe data elaborated in this project may help you with your decision on what Lego-Mindstorms-Editions-Comparison.ods, a LibreOffice Calc spread sheet, lists the pieces of all sets combined.
Columns H and K tell you which pieces to buy if you have either Home Edition + Expansion Set or Education Edition + ExpansionYou can filter the columns using the "Auto Filter" in the first row. The spread sheet document specifically targets the two sections "‘Upgrading’ Elements from Education Edition to Home Edition" and "‘Upgrading’ Elements from Home Edition to Education Edition" in Lauren's article. Specifically, the document will make the latter section less vague with regards to the "you’ll need to purchase [...] certain Technic building elements" statement. If you can't or don't want to install LibreOffice here are some free services that display or convert the spread sheet: convert-doc (view), Zamzar (convert),Some let you specify the raw document url directly. Google Docs and Zoho Docs also import the spread sheet. lego-mindstorms-pieces.py is a Python3 script to help with calculating and ordering required LEGO Mindstorms EV3 spare parts.
It has three commands: Generate the combined list of LEGO pieces from the 3 separate inventory lists (the combined list is what the above mentioned spread sheet is made of). It takes three file names as an argument. Output is sent to stdout. You can redirect it to a text file using the > operator on the command Generate a list of LEGO parts missing in the combination of the Edu Expansion set + Home or Edu Core, that only the other (omitted) set would have. The output has the format part:quantity,... and is sent to stdout. You can use the result as a shopping list in the order command. Add a list of LEGO parts and their quantity to the 'Shopping Bag' of LEGO'sA browser window will be opened, you'll be able to watch the browser do what you would normally do by hand, and execution will stop after all pieces have been added, so you can review and finalize(This is just to help you save time on entering 60+ piecesNothing is ordered on your behalf!)
For full instructions run: python3 lego-mindstorms-pieces.py {command} --help See the docs folder for sample output of the order command, and screenshots of prepared orders at LEGO's customer service platform. The order process at LEGO is highly automated. This usually means that orders with items out of stock, or orders that are too large will not be processed. LEGO notifies you with an automatic email in such a case. If you find a typo, an error, a critical mistake or feel there's some enhancement needed please feel free to open an issue, or even better clone the repository, apply your changes, and place a pull request. Your contribution is welcome! If you make changes to the raw data, e.g. raw-data/Brickset-inventory-*.csv, in a pull request please also regenerate the combined list and update the Calc spread sheet as follows: Then open Lego-Mindstorms-Editions-Comparison.ods and copy the contents of the regenerated Lego Mindstorms EV3 combined list.csv from a text editor
into the spread sheet as follows:The Warthog vehicle from the extremely successful Halo series is a nigh indestructible jeep-like vehicle with a mounted turret. Since the release of the first game in the series, LEGO fans have been working hard on making their own Warthogs out of the versatile construction bricks. See the links under Resources if you need visual aids for this design. WheelbaseThe vehicles are intended for off-road use. Find some large, off-road wheels from a jeep or similar vehicle. Ideally, find a set that has partial axles, instead of axles that go across the whole base. Build a small wheelbase that connects the sets of wheels, make it roughly square. Some sets also come with shock absorbers, which are perfect for the vehicle. ChassisBuild the base of the vehicle, making sure there are two seats for the passengers in the front. Also add a turret using one of the 4-stud-by-4-stud rotating bricks. Use gray bricks for the lower half of the vehicle, as you begin to build the exterior of the vehicle.
At the front, place a pair of hinges for the nose of the vehicle. TurretThe turret is where a soldier stands and fires from behind a shield. You can make the base of the turret out of a large hinge, and then add guns made from either posts or Technic bricks. Under Resources 2, there are a images of two or three kinds of guns that can be attached to a Warthog turret. Attach this turret to the rotating piece you added in Step 2. NoseUse one of the trapezoidal plates to build the front of the vehicle. The vehicle also needs a winch and the namesake tusks on the front. There are a number of pieces that will work for this, like the tusks from a Bionicle set or white horns set at 90-degree angles. Place these just under the short end on the front of the trapezoid. Attach the nose to the hinges placed in Step 2, and place it at about a 30 degree angle. Finishing TouchesAttach the windshield to the front of the car; ideally find a low and flat one that matches the contour of the nose. Over the windshield, and behind the seats, the Warthog needs a connected set of roll bars and a pair of roof lamps.
