DRU is a four wheeled automated vehicle with compartments to keep both hot and cold items at their respective temperatures. Rather than taking to the streets, the robot seems to mostly travel on the sidewalk and is able to navigate from starting point to destination with sensors that help it perceive and avoid obstacles. It has already been involved in a number of customer deliveries during testing. You can see it in action below:
For those wondering about theft or vandalism of the unit, comments by company reps seem to indicated that it will have both surveillance and security measures.
I could see this maybe working for locations with a lot of population density but I would guess, if anything comes of this, the final result will be a self-driving delivery car of some sort (but not a pizza thrower).
