AMR vs AGV: the definitive, neutral guide
AMR, AGV, ASRS, goods-to-person, autonomous forklift, tugger — what each one is, how it navigates, and when to pick it. Vendor-neutral, no spin.
An AMR (autonomous mobile robot) navigates freely with onboard SLAM and LiDAR, routing around people without fixed infrastructure. An AGV (automated guided vehicle) follows a fixed path — wire, magnet, or track. Choose an AMR for changing, mixed-route floors; an AGV for fixed, high-volume routes. This guide also covers ASRS, goods-to-person, autonomous forklifts, and tuggers, and where each one wins.

What these categories cover
The material-handling robot world is full of three-letter acronyms that get used interchangeably and wrongly. They are not the same thing, and picking the wrong category is an expensive mistake. This hub is the vendor-neutral map: what each one is, how it actually finds its way around your facility, and the single question that decides between them — does your floor change, or is it fixed?
Service Robot Co. is an integrator, not an OEM, so we have no horse in the race between categories. That is the point of this guide: an honest read on which automation fits your operation, with no pressure to land on the one thing we happen to sell. When you know the category you need, the application hubs below go a level deeper.

The one question that decides AMR vs AGV
Strip away the marketing and the choice comes down to one thing: does your floor and route change, or is it fixed? An AGV follows a guide path you install — magnetic tape, embedded wire, or a painted/QR track. It is reliable and cheap to run on a route that never changes, but moving the route means re-installing the guide, and it stops dead when something blocks the path. An AMR carries its own map. It navigates freely with SLAM (simultaneous localization and mapping) over LiDAR and cameras, routes around people and obstacles, and adapts as the floor changes — no infrastructure to install.
So: fixed, high-volume, rarely-changing route → an AGV is often cheaper and perfectly good. Changing layout, mixed routes, or you cannot shut the operation down to install track → an AMR. Most growing facilities pick AMRs because the flexibility matches how a real floor actually behaves, but there are genuine cases where an AGV is the right, lower-cost call.
How SLAM / LiDAR navigation actually works
An AMR localizes itself the way you would in an unfamiliar building: it builds a map and constantly checks where it is against that map. LiDAR sweeps the space with laser ranging to measure distances to walls, racks, and obstacles; cameras and other sensors fill in detail; SLAM software fuses it into a live map and a position estimate that updates many times a second. That is what lets an AMR route around a pallet someone left in the aisle, slow for a forklift, and pick a new path — none of which an AGV on a wire can do.
The trade-off is honest: that intelligence costs more per unit than a guide-follower, and a very high-volume fixed lane may not need it. Navigation capability should match the job, not the hype.
What "Robotics-as-a-Service" (RaaS) means here
Across all of these categories, RaaS is the financing model that folds the robot, its deployment, its service, and the downtime risk into one monthly fee instead of a capital purchase. It matters most in material handling because the deployment (mapping, integration, route-building) and the upkeep are where the real cost lives — the robot is the small part. RaaS moves that whole burden, and the risk, to the vendor. The full TCO math is in our RaaS-vs-buying guide.
The categories, defined
Every acronym in one place — what it is and when to pick it.
- AMR — autonomous mobile robot
- Navigates freely with onboard SLAM + LiDAR, carrying its own map and routing around people and obstacles with no fixed infrastructure.
- Pick it when: Your layout changes, you run mixed routes, or you can’t shut down to install track.
- AGV — automated guided vehicle
- Follows a fixed guide path installed in or along the route — magnetic tape, embedded wire, or a painted/QR track. Stops when the path is blocked.
- Pick it when: The route is fixed, volume is high and steady, and the path rarely changes.
- ASRS — automated storage & retrieval system
- Fixed infrastructure (cranes, shuttles, vertical lifts) that automatically stores and retrieves goods in dense racking. Maximum density, minimum floor.
- Pick it when: You need to pack the most storage into the least space with automated put-away/retrieval.
- Goods-to-person (G2P)
- Instead of walking pickers to shelves, the system brings stored goods (shelves or totes) to a stationary picking station — often AMR-driven.
- Pick it when: Picker walking time is your bottleneck and you want to cut steps, not add pickers.
- Autonomous forklift
- A self-driving forklift that picks up, moves, and stacks pallets without a driver, navigating autonomously or along set routes.
- Pick it when: You move and lift pallets and forklift drivers are hard to staff or expensive.
- Autonomous tugger
- A self-driving tow tractor that pulls a train of carts/trolleys point-to-point — typically zero infrastructure change.
- Pick it when: You tow carts on repetitive milk runs and want automation without re-laying the floor.
Comparison
AMR vs AGV, head to head
The factor-by-factor difference. Neither is "better" — they fit different floors.
| Factor | AMR | AGV |
|---|---|---|
| Navigation | Free / SLAM + LiDAR — carries its own map | Fixed guide path — wire, magnet, or track |
| Infrastructure | None to install — runs your existing aisles | Guide path must be installed + maintained |
| Obstacles / people | Routes around them, keeps moving | Stops and waits until the path clears |
| Changing the route | Re-map in software | Re-install the guide path |
| Best when | Layout changes, mixed routes, no shutdown possible | Fixed route, very high steady volume |
| Up-front cost | Higher per unit, no infrastructure | Lower per unit, plus infrastructure to install |
A general guide, not a substitute for sizing against your real floor — which we do on a walkthrough.
Which material-handling robot do you actually need?
Match the job to the category. When you know the category, the application hubs go deeper.
Floor layout changes; mixed routes; can’t shut down to install track
An AMR (autonomous mobile robot) — free navigation, no infrastructure.
One fixed, very high-volume route that rarely changes
An AGV (automated guided vehicle) — cheaper per unit on a fixed lane.
Dense storage + automated put-away/retrieval in a fixed structure
An ASRS (automated storage & retrieval system) — built infrastructure, maximum density.
Bring stored goods to a stationary picker instead of walking pickers to shelves
A goods-to-person system — often AMR-driven shelf or tote movers.
Move and lift pallets where forklift drivers are hard to staff
An autonomous forklift — see the material-handling hub.
Tow carts/trolleys point-to-point with no infrastructure change
An autonomous tugger — see the material-handling hub.
When automation is NOT the answer (yet)
A neutral guide owes you the honest "not yet" cases. Hold off when:
- Your volume is low and irregular — the payback period stretches past the point it makes sense.
- The route is genuinely one fixed lane at modest volume — a simple conveyor or a person may beat any robot.
- You are mid-redesign of the operation — automate the stable process, not the one you are about to change.
- You need it live next week — deployment and integration take real time; rushing it produces shelf-ware.
Why an integrator over a single OEM
Each OEM sells the category it makes, so each will tell you its category is the answer. An AMR vendor sells AMRs; an AGV vendor sells AGVs. Getting a neutral read — and then a working deployment across financing, integration, and nationwide service — is exactly the gap an integrator fills.
Service Robot Co. is OEM-neutral. We tell you which category actually fits, pick the right unit, surface buy-vs-RaaS financing, deploy and integrate it, and service it through a US engineer network. One vendor for sales, integration, financing, deployment, and service — not four, and not a sales pitch dressed as advice.
Common questions
- What is the difference between an AMR and an AGV?
- An AGV follows a fixed guide path you install — a wire, magnet strip, or track — and stops when the path is blocked. An AMR navigates freely with onboard SLAM and LiDAR, carries its own map, and routes around people and obstacles with no fixed infrastructure. Choose an AMR when your floor changes or you run mixed routes; choose an AGV for a fixed, high-volume route that rarely changes.
- How does an AMR navigate without tracks?
- An AMR uses SLAM — simultaneous localization and mapping. LiDAR sweeps the space with laser ranging to measure distances, cameras and sensors add detail, and SLAM software fuses it into a live map and a position estimate that updates many times a second. That is what lets it route around an obstacle and pick a new path, which an AGV on a fixed guide cannot do.
- What is ASRS, and how is it different from AMRs?
- ASRS (automated storage & retrieval system) is fixed infrastructure — cranes, shuttles, or vertical lifts — that automatically stores and retrieves goods in dense racking to maximize storage density. AMRs are mobile robots that move material across an open floor. ASRS is about packing storage tight; AMRs are about flexible transport. Many facilities use both.
- What does Robotics-as-a-Service (RaaS) mean?
- RaaS folds the robot, its deployment, its service, and the downtime risk into one monthly fee instead of a capital purchase. It matters most in material handling because the deployment and upkeep — not the robot itself — are where the real cost lives. RaaS moves that whole burden, and the risk, to the vendor.
- When should I choose an AGV over an AMR?
- Choose an AGV when you have one fixed, very high-volume route that rarely changes — there an AGV is often cheaper per unit and perfectly reliable. The moment your layout changes, you run mixed routes, or you cannot shut the operation down to install a guide path, an AMR is the better call because it needs no infrastructure and adapts.
