All Mowers - Getting Started
You will need the following to complete the project
1. Purchase STL or CAD Print Files
STL Files or CAD Data for the model you want to print can be purchased and downloaded from the Webshop. If you plan on modifying / personalising the Mower design its worth to get the CAD data as all the STL files can be generated from the CAD data.
2. Order parts yourself or buy a Build-Pack
There is a complete B.O.M. (Bill of Materials) included in the STL or CAD data pack with links to all components. The parts (depending on the model you build) will cost around €200-€250 to order with a typical delivery time of 30-60days
Alternatively you can order a build pack here in the webshop. A Ship DE option means the parts are shipped as 1 package from Germany and allows you to start building immediately.
There are 2 methods to build the ReP_AL Mower.
1. Using indivdual standard Arduino components
2. Using a ReP_AL PCB combined with Arduino components and PCB mounted components.
Both achieve the same result although the build is much easier and cleaner with the PCB as it takes care of a lot of the wiring.
PCB Bundle Example:
3. LiIon 18650 Batteries
To power the mower you will need a 3S 18650 Battery Pack. This will be created using single 18650 cells to make a pack. (not included in the build pack)
Build instructions are included for each mower type.
In total 18x 18650 cells are required for the 220 / 330 and LAM Mowers
In total 12x 18650 cells are required for the Little Monster Build
A Li-Ion protector circuit is also used (included in the build pack) to prevent under and over charge of the packs.
I recommend to use the Panasonic 18650B batteries. These are quality reliable batteries and worth the investment. They can be typically be sourced online. Look for packs with multiple cells as they are considerably cheaper.
The battery build section also includes some information on batteries if your unsure how to use them
4. Additional Features?
In addition to the standard build, there are additional features which can be added to the Mower. For example an onboard FPV camera.
Instructions to add these features can be found here:
5. GPS Module?
I am working on a cm accurate GPS module. If you want to add this to your build the instructions for this project can be found here:
