The store Grandma is going to is probably already wheelchair accessible, so a wheeled robot would work fine.

I'm sure that's the case where you live, but where I live our public transport isn't 100% disabled-accessible.

If you prefer, you can substitute "Like a robot delivery driver, who must deliver to flats without lifts" or "Like a robot cop, chasing truant teens through a mall" [1]

Fwiw we already have mall cop robots in California: https://www.theverge.com/2017/4/26/15432280/security-robot-k...

They cost about $7/hr each to employ (~$62k annually since they're 24.7): https://www.digitaltrends.com/cool-tech/knightscope-robots-i...
