Do not board the elevator with robot

Steve sez, "Warning sign du jour: 'Do Not Board the Elevator with the Robot.'"
After finishing my doctoral work, I returned to Stanford Medical School to finish up the MD part of my MD/PhD. During one of my last clinical rotations, I stopped to take an elevator up to a surgical unit. While waiting for the elevator, a large washing-machine-sized robot--a unit that had then been recently introduced at Stanford Hospital to pick up and deliver x-ray films--pulled up along side me. After waiting patiently together, we both entered the elevator. As the door closed, the robot began to whir and then quite rapidly spun around 180 degrees to re-orient itself for exiting.

The large spinning robot nearly knocked me down in the elevator. It was somewhat frightening to be trapped in an elevator with little clearance for a massive spinning robot.

I recall being somewhat concerned about what might happen if a fragile patient, walking along with an intravenous pump, or a medical team with a patient on a gurney, entered the elevator with the robot.

Please Do Not Board the Elevator with the Robot

(Thanks, Steve!)
