This is a multifunctional an relatively cheap robot platform, that can be operated by gCode commands or files and does NOT require a Raspberry Pi.

The code does works well, but some bugs may still be part of it. The documentation is mostly an awful mix of the english and german languages, but I hope to find the time as soon as possible to make it more understandable.

Buyable parts:
-Mecanum Car Chassis (ebay has multiple sets)
-NodeMCU-esp32 (v4 was my version)
-5 Arduino Nanos (4 are minimum to drive the Motors)
-2 L298N Motor driver modules
-some kind of battery (I used a 4.5 AH 12v battery, commonly used in scooters or motorcycles)
-6 HC-SR04 Ultrasonic sensors (optional)
- SSD1306 OLED Display (optional)
- Rocker Switch_KCD1-11_2pin (optional but recomanded)
- some cables, screws and spacers (details in the CAD files)
-everything that you want to mount on top, that can be controlled via I2C

Every file contained in this project was made with open-source software and can be adjusted to your own needs without any cost.
Every mecanical part can easily be bought in the internet or at least be manufactured with a 3D-Printer.
The required PCBs an be orderd with the uploaded gerber files for approximately 11 € plus shipping (~10€ for germany)
A soldering iron and some screwdrivers are the only required tools.

I wish a lot of fun to build and use this. If you find any problems please contact me. Maybe I can help or at least mention it here for everyone.
