OK, got something that may not even qualify for Pitstop, but... what kind of "vehcle" is this, seen cruising the aisles of WalMart: https://photos.app.goo.gl/YpiTSsEjBmVPAYpq6 The sticker on the bottom of the back of it says "CAUTION ROBOT AT WORK" and "WARNING: HIGH INTENSITY LIGHTS"
I tried getting closer to it to get a better picture of the labels and the QR code, but it was pretty evasive! On the tall pole, on the side not seen, appears to be several camera sensors. It was wandering around the Health and Beauty section, I think it is to scare away shoplifters?
