Mystery Delivery Robot - As Seen in the "Parking Lots of Silicon Valley"

Driving around Silicon Valley I came across this delivery robot testing- or that's what I assume it is. There was a similar vehicle tested a block from my house a few months ago (BoxBot.) Not sure who this belongs to. But like BoxBot it's a box on wheels with a Lidar on top and somebody walking around presumably guiding it.

Know what this is? Please let me know.....
