Programming
We use C++ in ArduinoIDE to program our microcontroller (Teensy 4.1). (See code-explanations) We also use Raspberry Pi Pico as part of our line sensor.
3D Printing
We design our parts in Fusion360. (See mechanical design/) All parts are printed in PLA.
PCB Design
We design our PCBs in KiCAD 7.0 and order from JLCPCB. (See pcbs/). The schematics are based on circuits we tested using breadboards.
All designs are original other than the BBR IR Seeker

Questions
How big is the Main pcb bottom PCB?
It measures 125.1 × 114.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Main pcb bottom use?
44 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Main pcb bottom KiCad files?
From the enenflash/YounglingSlayer repository on GitHub, at the commit this page was made from: the board is pcbs/main_pcb_bottom/main_pcb_bottom.kicad_pcb and its schematic pcbs/line_sensor-26-08/line_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main pcb bottom design in my own project?
Its repository states no licence, so its author keeps all rights: ask enenflash before reusing the design.
