[quote=no_such_reality] … As for tile robots, Carnegie Mellon did it back in the 90s, same concept as a DitchWitch.[/quote]
LOL, I’d be afraid this (electronic) creature would begin tiling everything in sight (vertical surfaces, etc) if left unsupervised :=0
WOW, I just skimmed your link and it’s actually an academic paper. The “robot” looks like an ice-rink icer! It’s way too large for residential use. I’m still skeptical that the tiles laid (in a ballroom?) by this machine won’t be crooked or have holes in the grout.
