AMRs vs. Burden Carriers: Which Does Your Facility Actually Need?
Autonomous mobile robots and electric burden carriers get evaluated against each other constantly, usually because both show up in the same budget line: "reduce the time people spend walking." They solve that problem in fundamentally different ways, at very different price points, with very different deployment timelines.
This page lays out the honest comparison. TexTrack builds burden carriers, not AMRs — and there are operations where an AMR is clearly the better answer. Knowing which side you are on matters more than the brand you pick.

An autonomous mobile robot removes the person from the trip. It navigates on its own, using onboard sensing and a facility map, and it needs no operator. It is a software and infrastructure project as much as a vehicle purchase.
A burden carrier or stock chaser keeps the person and makes the trip faster. The operator drives it, decides where it goes, and does the work at the other end. It is a vehicle purchase, and it works the day it arrives.
The question is not which technology is more advanced. It is whether the trip itself is the problem, or whether the person needing to be at the other end is the point.
Side by Side
| Factor | AMR | Burden carrier / stock chaser |
|---|---|---|
| Operator required | No | Yes — the operator is the point |
| Typical capital cost | Substantially higher per unit | Substantially lower per unit |
| Deployment time | Weeks to months — mapping, integration, testing | Immediate — charge it and drive |
| Infrastructure needed | Facility mapping, often WMS/WCS integration, charging stations, network coverage | A charger and an outlet |
| Handles the unexpected | Follows programmed logic; exceptions need handling | The operator adapts in real time |
| Facility change tolerance | Layout changes may require remapping | None — the operator just drives differently |
| Best at | High-volume, repetitive, predictable point-to-point moves | Variable routes, judgment work, tasks needing a person on site |
| Scales by | Adding units and throughput | Adding units per operator |
When an AMR Is the Right Call
- The same move happens hundreds of times a day along a predictable route
- Nobody needs to be at the destination — only the material does
- Your facility layout is stable and well documented
- You have the IT capacity for WMS integration and ongoing support
- Volume justifies a longer payback period
If most of those are true, you are looking for an AMR vendor, and we are not one.
When a Burden Carrier Is the Right Call
- The person needs to be at the destination — maintenance calls, inspections, picking, quality checks
- Routes vary day to day and task to task
- The job involves judgment, troubleshooting, or handling exceptions
- You need it working this month, not next quarter
- Your aisles are tight enough that a large autonomous platform would not fit anyway
- You want the capital cost of one AMR to buy a small fleet instead
The Case for Running Both
These are not mutually exclusive, and the strongest operations often use both. AMRs take the repetitive, high-volume material moves off the floor. Burden carriers and stock chasers move the people who still have to be somewhere — technicians, supervisors, quality staff, pickers working variable routes.
Splitting the problem that way usually costs less than forcing either technology to cover the whole thing.
What a Stock Chaser Adds
A stock chaser is a burden carrier configured specifically for order picking and replenishment — the operator plus totes, cartons, or a small deck load. It is the format most often compared against AMRs in fulfillment environments, because both are aimed at the same pick-path inefficiency.
The distinction: an AMR brings the shelf to the picker or carries a completed tote away. A stock chaser makes the picker faster along their own path. Which one wins depends heavily on your SKU velocity distribution and how much of the pick path is genuinely predictable.

Frequently Asked Questions
What is an AMR in a warehouse?
An autonomous mobile robot — a self-navigating vehicle that moves materials without an operator, using onboard sensors and a facility map rather than fixed guidance like tape or wire.
What is the difference between an AMR and an AGV?
An AGV follows fixed infrastructure — magnetic tape, wire, or markers. An AMR navigates dynamically and can route around obstacles. AMRs cost more and are more flexible; AGVs are simpler and cheaper where routes never change.
Is a burden carrier cheaper than an AMR?
Substantially, on both capital cost and deployment. The tradeoff is that it still requires an operator — it makes a person faster rather than removing the person from the loop.
Does TexTrack sell AMRs?
No. TexTrack builds operator-driven electric burden carriers. If your application genuinely calls for autonomy, we will say so.
Can AMRs and burden carriers work in the same facility?
Yes, and often should. AMRs handle repetitive high-volume material moves; burden carriers move the people who still need to get somewhere.
