Best autonomous mobile robots, 2026.
A vendor-neutral comparison of the autonomous mobile robots warehouses and plants actually deploy — self-navigating robots that move totes, carts, and pallets and bring goods to people. AMRs plan their own paths with SLAM and onboard sensing, so unlike fixed-path AGVs they route around obstacles and reconfigure in software rather than tape on the floor.
The specs that actually matter for AMRs.
An AMR is judged less on raw speed than on how well it fits your loads, your layout, and your software — the numbers that decide fit differ from a fixed robot arm.
Payload
The heaviest load the robot carries, from a few kilograms for tote and shelf robots up to ~1900 kg for heavy pallet platforms. Size it to your worst case, not your average.
Navigation
How the robot finds its way. Modern AMRs use SLAM and natural-feature mapping to plan their own paths; older AGV-style systems follow magnetic tape or wires on fixed routes.
Throughput & fleet size
One robot rarely matters — what counts is picks or moves per hour across a coordinated fleet, and how many robots the traffic manager can run in your space.
Form factor
Tote, cart, pallet, or piece-pick. The chassis and lift decide what the robot can carry and how it hands off to people or fixed equipment.
Fleet management software
The traffic controller and task allocator that keeps robots from colliding, balances work, and manages charging. Often the real differentiator between platforms.
Safety & human environments
Safety-rated scanners, speed and separation, and certification decide whether robots can share aisles with people rather than run behind fencing.

Four platforms worth knowing well.
MiR — the industrial AMR transport leader
MiR (Mobile Industrial Robots, part of Teradyne) is the default for industrial material transport, with a range that spans light tote movers up to 1350 kg pallet platforms and a mature fleet manager that coordinates mixed fleets across a plant. The ecosystem of top modules, shelf lifts, and pallet hooks lets one platform family cover many transport jobs, which is why it is a common first AMR for manufacturers moving totes and carts between cells.
OTTO Motors — heavy in-plant transport
OTTO Motors (part of Rockwell Automation) specializes in heavier material transport, with platforms rated up to roughly 1900 kg for pallets and large loads on busy plant floors. The tie to Rockwell's automation stack and a fleet manager built for high-traffic industrial environments make it a common choice where the job is moving heavy loads reliably alongside people and forklifts.
Locus Robotics — fulfillment piece-picking at scale
Locus builds collaborative fulfillment AMRs that guide human pickers through a warehouse, carrying totes and consolidating orders so people walk less and pick more. It is deployed at large scale in e-commerce and retail distribution, typically under a robotics-as-a-service model, and is known for driving measurable units-per-hour gains without re-racking the building.
Geek+ — goods-to-person and sortation
Geek+ is a broad AMR vendor whose goods-to-person robots bring shelves and racks to pick stations, paired with sortation robots that route parcels and orders. The range spans light picking to heavier storage and sortation, making Geek+ a common choice for operations that want storage, retrieval, and sorting from one supplier.
Which AMR fits your job.
| If you… | Consider… | Why |
|---|---|---|
| Move totes or carts between cells | MiR, Fetch | Proven industrial transport at tote and cart scale |
| Move heavy pallets | OTTO Motors, Vecna Robotics | Payloads up to ~1900 kg for heavy loads |
| Run e-commerce fulfillment picking | Locus Robotics, 6 River Systems | Collaborative piece-picking that scales with orders |
| Want goods-to-person storage | Geek+, inVia Robotics | Bring inventory to stations instead of walking to it |
| Need low-capex, flexible automation | RaaS (inVia) | Subscription pricing avoids up-front capital outlay |
An AMR is a fleet, not a point solution.
A single robot rarely delivers the outcome. To move real work an AMR needs fleet management software that assigns tasks and controls traffic, WMS/MES integration so robots act on live orders and production signals, charging and infrastructure to keep the fleet running, and a safety plan for shared aisles with people. Buying one robot is not the same as deploying a working system.
That is why AMR projects are scoped as fleets and integrations, not individual machines. For the tasks a fixed robot performs instead, see our robot task guides; for who designs and installs these systems, see material-handling integrators.
Ten questions to ask before choosing an AMR.
- What payload and form factor do my loads actually require?
- What navigation type does it use — SLAM/natural-feature or fixed-path?
- What fleet size and throughput does my operation need?
- How capable is the fleet-management software at traffic and tasking?
- Does it integrate cleanly with my WMS or MES?
- What charging and infrastructure does the fleet require?
- Is it safety-rated to run in aisles shared with people?
- How well does the platform scale as I add robots and zones?
- What is the all-in cost — per-unit purchase or RaaS subscription?
- Where is service, and what is the support and response plan?
We build the manipulation cell AMRs feed.
Relling focuses on the physical-AI manipulation cell — the arm plus vision, process, fixturing, safety, and programming that picks, places, and handles parts. AMRs complement that cell by moving totes, carts, and pallets to and from it, so transport and manipulation work as one flow on your floor. If you're automating material handling, AMRs and a Relling cell are complementary halves of the system.

What is the best AMR in 2026?
There is no single best AMR — the right platform depends on payload, role, and environment. For industrial material transport, MiR and OTTO Motors lead. For e-commerce and warehouse fulfillment, Locus Robotics, Geek+, and 6 River Systems lead. The best choice depends on the payload you move and whether your job is transport, goods-to-person, or piece-picking.
What is an AMR and how is it different from an AGV?
An autonomous mobile robot (AMR) navigates autonomously using SLAM, natural-feature mapping, and onboard sensors, so it can plan its own path and route around obstacles and people. An automated guided vehicle (AGV) follows a fixed path defined by magnetic tape, wires, or reflectors and stops when something blocks it. AMRs are more flexible and easier to reconfigure; AGVs are simpler and can be lower-cost for fixed, repetitive routes.
What payload do AMRs carry?
AMR payloads range from a few kilograms for light tote and shelf robots up to roughly 1900 kg for heavy pallet and material-transport platforms. Match the platform to the heaviest load and the form factor — tote, cart, pallet, or piece-pick — your operation requires.
How are AMR fleets managed?
AMR fleets are coordinated by fleet-manager software that assigns tasks, plans traffic, and manages charging, integrated with your WMS or MES so the robots act on real orders and production signals. The quality of that software and its integration often matters more than any single robot's specs.
How much do AMRs cost?
AMRs can be bought per unit as a capital purchase, or deployed under a robotics-as-a-service (RaaS) subscription that bundles the robots, fleet software, and support into a recurring operational fee. RaaS lowers up-front capex and is common for fulfillment picking; per-unit purchase is common for fixed industrial transport.
What are AMRs used for?
AMRs are used for material transport between cells and areas, goods-to-person storage and retrieval, e-commerce and warehouse fulfillment picking, and line-side delivery in manufacturing. They move totes, carts, and pallets so people and fixed equipment do not have to.
