Are service robots safe around people?
Service robots are designed to yield. When a person or object appears in the path, the robot slows or stops and waits rather than continuing. Safety in a venue is shared, though: layout, floor condition and where robots are allowed to travel matter as much as the machine's own sensing, and should be settled during the site survey.

The default behaviour is to give way
The most important safety property of a service robot is unglamorous: when something is in the way, it stops.
Not "negotiates around". Not "warns and proceeds". Slows, stops, waits for the path to clear, then continues. It applies equally to a child, an adult, a suitcase or a dropped napkin, because the robot is not classifying the obstacle — it is observing that the path is not clear.
People occasionally find this frustrating. A robot waiting patiently behind a group of guests who have stopped to talk looks inefficient. It is the correct trade-off, and a machine that resolved it the other way would not belong in a room with customers in it.
Safety decided at survey time, not at run time
A lot of what makes a deployment safe is settled before the first task runs.
Routes come from a map made during installation, which means areas the robot should never enter are excluded then — stairs, back-of-house, anywhere with a lip or a drop. That is a configuration decision, not something the robot has to work out reactively in the moment, and deciding it up front is much stronger than hoping sensing catches it.
The site survey is where a venue should be difficult on purpose. Where are the steps? Which corridor narrows at service time? Where do deliveries get stacked?
What is the venue's responsibility
Shared, and worth being explicit about:
- Floor condition. Spills, cables and thresholds are the venue's.
- Route clearance. A corridor routinely blocked produces a robot routinely waiting.
- Staff practice. Handovers matter here — many tasks wait for a person to confirm, and a robot left waiting in a walkway because nobody acknowledged it is an obstruction created by workflow, not by the machine.
- Guest behaviour. You cannot control it, which is exactly why the robot yields by default.
What we will not claim
We will not publish safety certifications, incident rates or comparative figures. Certification belongs to the robot hardware and its manufacturer, and we are not going to summarise somebody else's compliance position on a marketing page. Ask us about the specific model being proposed for your venue and we will point you at the manufacturer's documentation.
Liability is contractual. Any supplier answering that question in one confident line on a web page is simplifying something that deserves a lawyer.

Frequently asked questions
What does the robot do if a child runs in front of it?
- It slows or stops and waits for the path to clear. The behaviour is the same for a child, an adult or a dropped bag, because the robot is not making a judgement about what the obstacle is — only that the path is not clear.
Are robots safe around stairs and lifts?
- Routes are planned over a map made during installation, so areas a robot should not enter are excluded at that point rather than being avoided reactively. Stairs, back-of-house zones and anywhere unsuitable should be settled in the site survey, before the first task runs.
Who is responsible if something goes wrong?
- Responsibility is shared between the hardware's certified safety behaviour, the deployment configuration and the venue's own operating practice. Specific liability is a contractual matter, and any supplier giving you a confident one-line answer on a web page is oversimplifying.

What is a service robot?
A service robot performs useful work alongside people rather than inside a cage. The definition, the categories, and where the boundary sits.
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.
Service robot battery life and charging
Why battery is an input to the dispatch decision rather than an alarm, how automatic charging works, and what charger placement does to a venue's effective capacity.
