I foresee an uptick in trompe l’oeil artwork of stairways, “speed bumps”, open doorways, fountains, strollers, entire landscapes etc to fake out and confuse auto-bots.
Should be massive fun.
Strategically placed mirrors should be hysterical also and anechoic material for those that use ultrasonic range-finding.
Then there’s graffiti tagging. Going to be amusing.
Admittedly, the system that lets my Roomba detect stairs also causes it to think a dark floor, or a black segment of an area rug, is a ledge it needs to avoid. Not that drowning is acceptable, but I can certainly imagine the K5 programmers making a different set of tradeoffs.
Everybody beat me to it, I remember a cartoon years (decades?) ago, with Dalek at foot of staircase: “Well that buggers our plans to take over the universe”.
