Service robots in multi-floor buildings
In a multi-floor building each level needs its own map with its own named points, so any destination can be addressed by name. Whether one robot can serve several floors depends on lifts: the hardware must be able to call and ride one, and the building's lift must be integrable. That single question shapes the whole deployment.

One question decides the shape of the deployment
Can the robot use the lift?
Everything else about a multi-floor deployment follows from the answer, and it is worth establishing before any other conversation happens. It has two halves, and both must be yes:
- Can the robot hardware call and ride a lift? A capability of the specific model.
- Can this building's lift be integrated? A property of the building, and frequently the harder half. Older installations often simply cannot.
Neither half is a software question, which is why we treat it as a survey item rather than something to answer on a web page.
If the answer is yes
One fleet can serve the whole building. Each floor still has its own map and its own named points of interest, so any destination on any level is addressed by name — the instruction to send a robot to a room on the fourth floor looks exactly like the instruction to send it to a table on the ground floor.
How mapping and named points work covers the mechanics.
Worth planning for: lift journeys consume real robot-minutes, including waiting for the lift to arrive and for it to be free of people. Fleet sizing should account for that, because a lift-dependent trip is often several times longer than a same-floor one.
If the answer is no
Two honest options, both of which work:
A robot per floor. Each unit serves its own level with its own map. Costs more in units, but each one does short, reliable runs and no deployment depends on a lift's availability at service time.
Deploy only where the work is. Frequently the best answer. If ninety per cent of the carrying happens on one floor, automate that floor and leave the rest alone. A focused deployment that works beats a building-wide one that half-works.
The case for choosing deliberately
The failure mode here is not technical. It is a building-wide deployment sold on the assumption that lift integration would be straightforward, discovered to be impossible after the units arrived, and quietly reduced to one floor anyway — at the price of several.
Establishing the lift position at survey time costs an hour and is the single highest-value question in a multi-floor building.

Frequently asked questions
Can a service robot use a lift?
- It depends on both the robot hardware and the building's lift. Some robots can call and ride a lift where an integration exists; many buildings have lifts that cannot be integrated at all. It is a survey question about your building rather than a software feature.
What if the lift cannot be integrated?
- Then the realistic options are a robot assigned per floor, or a deployment limited to the floors where the work actually is. Both are workable, and choosing one deliberately at survey time is far better than discovering the constraint after purchase.
How are floors represented?
- Each floor has its own map and its own named points of interest, so a destination on any level is addressed by name rather than by coordinates. That keeps instructions identical whether the target is on the ground floor or the fourth.

How service robots navigate
Mapping, named points of interest, route planning and obstacle avoidance — how a service robot finds its way, and why map drift is what actually breaks deployments.
How many robots does a restaurant need?
Fleet size follows trip length and trip frequency, not floor area. A method for sizing a deployment before anybody quotes you a number of units.
What drives the cost of a service robot?
The robot is one line of several. Site survey, mapping, integration, training and support all vary by venue — what to ask before comparing quotes.
