If you hate it so much, I would recommend instead buying one of the autonomous lawn mowers that have been on the market for years now, set it and forget it. (Maybe take it in for the winter.)

I've heard good things about the Husqvarna 450 especially.

Spoiler alert: there is no computer vision involved, still works perfectly even for large lawns; our local university even uses them in campus parks.
