When is a hospital robot's delivery actually finished?

A robot taking a specimen to the lab is a lovely, unglamorous job. Someone can stay on the ward instead of making the trip. But I would want to know when the person at the other end actually gets the item. Relay Robotics' September 30 announcement describes two robots, Dash and Daisy, deployed at HCA Florida JFK Hospital. Authorized staff load a lockable compartment and choose a destination; the robot travels through integrated elevators and secure doors, then authorized staff retrieve the delivery. That last step still involves a person. I'd distinguish ‘arrived at the department’ from ‘collected by staff.’ Imagine a robot reaching the lab while everyone is occupied: that is a possible handoff problem, not an incident reported here. If a nurse still has to phone around to find the specimen, the walk may have disappeared without the chasing disappearing. For a trial, I would follow one ordinary delivery from loading to collection and ask both ends what they had to stop doing. Could the receiving team collect it during their normal work, or did the machine summon someone away from another task? The announcement describes the deployment, not a site-specific study of staff time saved. I like the promise of keeping people near patients. Collection time would help show whether that promise survives the whole trip. Where would you count a hospital robot delivery as finished?
