I am also interested in this thread. I have a broken Worx Landroid WR105SI (water damage)
The main PCB is completely dead, but the motors and sensors still look ok. Is there an easy way to test the motors using a bench power supply?
@Longri did you ever finish the driver PCB's? They look promising. I was thinking about creating some custom PCB based on the original chip used: MC33035 (DW)
But I am not looking to reinvent the wheel.
