AGV vs AMR
AGVs and AMRs both move stock around a warehouse without a driver, and the industry uses the two terms almost interchangeably in casual conversation. The distinction that actually matters is how each one decides where to go, and that decides where each one fails.

Two different ideas of "automated"
An AGV, an automated guided vehicle, follows a fixed, infrastructure-dependent path: magnetic strips, tape or embedded wires laid into the floor. It goes where the infrastructure tells it to go, nowhere else, and it does that with high reliability on repetitive, predictable routes.
An AMR, an autonomous mobile robot, finds its own way dynamically using onboard sensors, LiDAR and SLAM mapping. It builds and updates its own understanding of the space, which means it can reroute around an obstacle, a person or a repositioned pallet without anyone reprogramming a path. That description reflects the working consensus among equipment vendors and systems integrators rather than an independent engineering study, but it's consistent across the sources this research checked.
Where AGVs actually fail
An AGV fails badly when the environment changes and the infrastructure doesn't. Block the magnetic strip with a stray pallet, change the layout, or need the vehicle to serve a new area, and the fix is a facilities job, not a software update. AGVs also tend to demand more of the building itself — a defined, protected path running through aisles sized to suit it — which is part of why they suit high-volume, repetitive, predictable tasks better than flexible, changing ones.
Where AMRs actually fail
An AMR's flexibility comes with its own ceiling: payload and lift stability. Many SLAM-guided AMRs on the market are built for tote-sized, lighter loads rather than heavy palletised freight, and pushing one past its designed payload isn't a software problem to fix, it's a hardware limit. An AMR fleet also depends on a consistent, well-lit, sensor-friendly environment to operate reliably — the same floor and layout conditions that matter for other automated equipment matter here too.
The two side by side
The practical decision usually comes down to how stable the site's layout and task pattern actually are, not which technology sounds more advanced. A fleet doing the same predictable reach-truck-style run between two fixed points, day after day, is a reasonable AGV case; a fleet supporting shifting pick-path work across a changing SKU mix leans AMR.
| AGV | AMR | |
|---|---|---|
| Navigation | Fixed path — magnetic strip, tape or wire | Dynamic — onboard sensors, LiDAR, SLAM mapping |
| Infrastructure needed | Significant — path has to be installed and protected | Minimal — deploys without major facility change |
| Typical payload | Can be built for heavy, palletised loads | Often lighter, tote-scale loads on common models |
| Handles a changed layout | Poorly — path has to be physically altered | Well — reroutes around the change |
| Best suited to | Repetitive, predictable, high-volume routes | Variable tasks and a layout that shifts over time |
Where this fits in the wider automation decision
AGVs and AMRs both sit lower on the automation ladder than goods-to-person picking or full ASRS — they move stock, but they don't usually replace the storage system itself. For a site weighing a mobile-robot fleet against a fixed shuttle or crane-based ASRS investment, the honest starting question is the same one that governs when heavier automation makes sense at all: how stable is the layout, and how repetitive is the task, over the years the equipment needs to earn its cost back.
Common questions
- What's the simplest way to tell AGVs and AMRs apart?
- An AGV follows a fixed path laid into the floor — magnetic strip, tape or wire. An AMR finds its own way dynamically using its own sensors, so it can reroute around obstacles without anyone changing the infrastructure.
- Which is cheaper, an AGV or an AMR?
- This page doesn't have a verified cost comparison to offer — the honest answer depends heavily on how much infrastructure an AGV deployment needs on a given site, and that varies too much to state as a general rule.
- Can AMRs carry a full pallet load?
- Some can, but many common SLAM-guided AMR models on the market are built for lighter, tote-scale loads rather than heavy palletised freight. Payload capacity is a hardware limit specific to the model, not something to assume either way.
- Do AGVs or AMRs need a warehouse management system to work?
- Both typically integrate with a warehouse management system to receive tasks and report status, though the depth of that integration varies by vendor and isn't something either technology can be assumed to include out of the box.
