When my daughter went o Thee Ohio State University these things were all over the place delivering food...they stopped them for a while in 2022 after they found out the software came from Russia, but they eventually returned.....
Whenever i visited her on campus i would always screw with these things- standing in front of them, moving away, jumping back in front, watching them start then stop then start again and try to maneuver around me....
These are the ones that are benevolent precursors to T 1000 prototypes.
