Using slic3r as the coverage planner for mowing is an extremely cool and clever idea.

When you delve into the source code of 3d printer slicers, you realise the actual smart work really is done inside polygon libraries. Ie. 'take this polygon and inset it by 1mm, returning the smaller polygon and the old perimeter'.

Using that primitive, you can make a lawn mower.

I was impressed to see a decent traveling salesman estimate algorithm in my last romp through a slicer's source code.

I'd like gyroid infill for my lawn, would look cool perhaps :-)
