For those who are vision or mobility impaired in particular, the bots can provide a tripping hazard or physical obstacle, groups like the Accessibility for Ontarians with Disabilities Act Alliance argue, calling tools like Geoffrey a "a substantial and worrisome new disability barrier impeding people with disabilities in their safe use of public sidewalks and other paths of travel."
I'd expect that the oblivious-to-surroundings-until-last-moment-smartphone user would also be likely to trip over these tiny pink delivery robots. Their occasional glance up from their precious smartphone to check for incoming items works for human-sized objects approaching the smartphone user but would most likely miss these one-foot-high delivery bots.
