Description
This GitHub repository contains the code and documentation about student-built MiniSumo robot "SUMEC". MiniSumo robots are small autonomous robots designed to compete in MiniSumo competitions, where they attempt to push their opponents out of a ring. Our other repository "Sumec-Remote" is a forked repo from p1rse, created for our own MiniSumo start remote, PCB is ours, schematic was copied from "p1rse/robot-sumo-start-module".
Contents
-
-3D- Provides CAD files for the mechanical components of the robot, such as the chassis and sensor mounts.
-
-CODE- Contains the source code for the MiniSumo robot, including firmware for microcontrollers, sensor libraries and control diagrams.
-
-DOCS- Includes robot documentation, rules for specific tournaments, and extras.
-
-PCB- Includes PCB files, we are using KiCAD for PCB designing.

Questions
How big is the Sumec PCB?
It measures 95 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sumec use?
61 parts, built around the ESP32-S3-WROOM-1-N8, USBLC6-2SC6, TYPE-C-31-M-12 and XT30PW-M. 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 Sumec KiCad files?
From the bismarx-v1/Sumec-MiniSumo repository on GitHub, at the commit this page was made from: the board is -PCB-/_archive_old/SUMEC_MK_III/sumec.kicad_pcb and its schematic -CODE-/Controler_code/Controler/Controler.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sumec design in my own project?
Its repository states no licence, so its author keeps all rights: ask bismarx-v1 before reusing the design.
