Design & build
All the relevant documentation should be found below. Feel free to come and play with ours or build yourself one.
Alternative firmware paired with remote control which can be found here.
Sumorobot PCB has seen many iterations over the years and has now arrived on a semi-custom design with ESP32. Silver Kuusik has contributed a lot to the design in it's current form. The KiCad design of the PCB created by Lauri can be found here.
That design should be easy to mill with CNC and easy to solder by hand.
3D printable sumorobot frame has been designed mostly by Marek Juhanson. Final version with optional plow was created by Lauri Võsandi with OpenSCAD. Additionally case for sumorobot remote using WeMos D1 board and Funduino Joystick expansion board was created by Lauri. The sources for both can be found here
