Sumo robot build by me! Designed for RoboRave competition 2026
- 10x10cm robot footprint (max 18-25cm, i think about adding flags)
- max 1kg
- metal parts (i think i will order BJ parts from jlc beacuse they are cheapest, still not cheap tho)
- 4 Distance sensors
- 4 line sensors
- IMU
- shielded motors :)
- EPROM memory on board
- strong and fast stm32H5 mcu on board
- 7.5 gear ratio
- two big external mosfters motor drivers capable of high current
- two strong motors (8A max each... it will be gooood)
- not tested yet
- Buzzer!
no buzzer :(- not tested yet
- still in development
- not tested yet

PS. Please - dont copy my work. Watch it, rewiev it, learn from in, take notes - but dont just change a few things and rebuild it. Do better! Make your own better version! Beat me at the next competition!!!
This project is out here to inspire you, not to be copy and pasted!
If you want to take a look:
- 3D files are in the "3DP" folder
- Board gerber files are in the "altiumik/name of the PCB, for example "Riser_IR_receiver_PCB"/Project Outputs blah blah blag" You will find them, dont worry
- Wiring? Everything is written on the PCBs. If you need more, take a look at the PCB files in "altiumik" folder
This project uses:
- Altium Designer - routing PCB
- Autodesk inventor - designing all of the parts and assembliess
- stm32CubeIDE - programming the MCU
- Hack Club Forge - yea, it is my project :)
