Thanks for mentioning this. I did not know it existed, and it looks very interesting. I might try to "upgrade" my 7-year-old vacuum robot.
Unlike Valetudo, this uses the chassis and the motor of the lawn mower, but completely replaces electronics.
The Mowgli project is reusing the mainboard of the original lawnmower (might be enhanced with a RPi though). It's not currently as well-baked (or at least, well-trodden) as the default OpenMower approach which does indeed involve ripping out the mainboard and replacing it.
Thanks for the link, this is super useful. I will probably use both valetudo and openmower soon! Is there anything comparable for security cameras?
