Direct answer
Hospital robots can use compatible elevators through a project-specific interface that manages calls, car entry, floor selection, exit and failure handling.
Core integration sequence
The fleet requests service, receives lift status, navigates into the car, selects or requests the destination floor, exits and confirms route continuation.
Safety and failure states
The design should address blocked doors, full cars, communication loss, emergency modes, timeouts, safe waiting and manual recovery.
Stakeholders
Hospital facilities, IT, the elevator supplier, robot integrator and safety team should approve the interface and test plan.
