AMR vs AGV: which does your facility need?

The short answer: choose an AMR when your floor layout changes, you run mixed routes, or you can't shut the operation down to install infrastructure. Choose an AGV when the route is fixed, the volume is high and steady, and the path rarely changes. An AMR navigates your existing aisles on its own and routes around people; an AGV follows a fixed path — a wire, magnet strip, or track — so it needs that path built and maintained.

Most growing facilities pick AMRs because the flexibility matches how a real floor actually behaves. But there are real cases where an AGV is the better call. Below is how to decide, and where each one wins.

What is the actual difference?

Both move material across a facility. The difference is how they find their way:

• An AGV (automated guided vehicle) follows a fixed guide path you install in the floor or along the route — magnetic tape, embedded wire, or a painted/QR track. It is essentially a robot on rails without the rails being steel. Change the path and you re-install the guide.
• An AMR (autonomous mobile robot) builds a map of your space and navigates it on its own. It routes around people, pallets, and obstacles in real time, and adapts when you move a rack or change a pick face — no track to lay, no floor to cut.

That single difference — fixed path vs. free navigation — drives every other trade-off.

AMR vs AGV, side by side

| Factor | AGV (fixed-path) | AMR (free-navigating) | | --- | --- | --- | | How it navigates | Wire, magnet tape, or track you install | Builds its own map; navigates freely | | Infrastructure to install | Yes — guide path along every route | None — no rails, no floor changes | | Handles a changing floor | Poorly — re-route means re-install | Well — re-maps when the layout shifts | | People and obstacles in the path | Stops and waits | Routes around them and keeps moving | | Best volume profile | High, steady, repetitive | Variable or mixed, including peaks | | Time to first run | Longer — path has to be built | Shorter — map the space, set routes | | Flexibility to add new routes | Low | High | | Best when | The route never changes | The floor and the work both change |

When an AMR is the better call

An AMR fits most commercial and warehouse floors, and especially these cases:

1. Your layout changes. If you re-slot racks for a season, add a pick face, or move the dock workflow, an AMR re-maps instead of needing a new guide path installed.
2. You run mixed routes. When robots haul totes to packing one hour and pallets to the dock the next, free navigation handles the variety that a single fixed path can't.
3. You can't shut down to install. Laying guide infrastructure means downtime and floor work. An AMR maps a live operation without stopping it.
4. People share the floor. AMRs route around workers and forklifts and keep moving, instead of stopping dead at a blocked path.
5. You want to scale with the season. Add units for a peak and hand them back after — without owning idle hardware or maintaining unused track. See the AMRs we rent and service.

When an AGV genuinely wins

We will tell you when an AGV is the better fit. It usually is when:

• The route is fixed and almost never changes — a single high-volume loop between two fixed points.
• The volume is steady and predictable, so a dedicated path earns its keep around the clock.
• The environment is tightly controlled, with little foot traffic crossing the route.
• You are moving very heavy, uniform loads on a repetitive cycle where simple, rugged path-following beats adaptive navigation.

If that describes a specific lane in your facility, an AGV on that lane can be the cheaper, more rugged choice. For everything that changes — which is most of a real floor — an AMR is usually the better fit.

How Service Robot Co. fits in

The robot is the easy part. Getting it deployed, integrated into your operation, and kept running is the hard part — and that is the whole job we do. We are one vendor for all five things: we help you pick the right robot, integrate and deploy it on your floor, finance it as a monthly rental, and service it nationwide.

• We match the robot to the work. Tell us the floor, the loads, and the routes, and we recommend AMR or AGV honestly — including telling you when an AGV is the right call for a fixed lane.
• We deploy and integrate it. On-site setup, mapping or path configuration, route building, and a team walkthrough so it runs on day one — not after a month of tuning.
• We finance it as a rental. Rent throughput by the month instead of buying a robotics project, so a changing floor doesn't strand a capital purchase.
• We service it nationwide. Repairs and parts across all 50 US states, backed by 3,000+ service engineers in the US: 10-minute remote triage during business hours, 24-hour nationwide on-site dispatch, and 24/7 emergency response. If a unit goes down, we swap in a backup and you keep moving.

Common questions

Is an AMR always better than an AGV? No. An AMR is more flexible and needs no installed path, which fits most floors. But for a single fixed, high-volume route in a controlled space, an AGV's simple path-following can be the more rugged and cost-effective choice. The right answer depends on your routes, not on which is newer.

Do AMRs need any floor changes or tracks? No. The AMRs we rent navigate your existing aisles and route around people and obstacles — no rails, no magnets, no floor work. We handle the mapping and route setup during deployment.

Can I switch from AGVs to AMRs later? Yes. Because you rent, you are not locked into a fleet. You can start with AMRs on the routes that change and keep AGVs on a fixed lane if one already serves you well — or move entirely to AMRs as your floor evolves.

Which one is faster to get running? Usually the AMR. An AGV needs its guide path built before it can run; an AMR maps your space and is configured for its routes during deployment, so first run comes sooner.

Decide on your floor, not the label

AMR or AGV is a facility decision, not a tech-trend decision. Pick an AMR when your floor changes, your routes mix, or you can't stop to install infrastructure; pick an AGV for a fixed, high-volume lane in a controlled space. For the full breakdown — plus ASRS, goods-to-person, autonomous forklifts, and tuggers — see our AMR vs AGV definitive guide and the material handling robots guide. If you are not sure which fits, tell us the job and the site — we will recommend the robot, quote the rental, and keep it serviced.
