AGV vs AMR — when each wins.
AGVs and AMRs are different generations of warehouse and factory mobile robotics, with different assumptions about navigation, infrastructure, flexibility and TCO.
AGVs follow fixed paths defined by magnetic tape, wire-guidance or barcode markers; AMRs navigate dynamically with LiDAR or visual SLAM. This is the operator-level comparison for procurement teams choosing between them — and the case for hybrid fleets governed by VDA 5050.
The category difference
AGVs (Automated Guided Vehicles) are fixed-path robots that follow markers — magnetic tape, embedded wires, optical lines, or fixed-position QR codes. They're deterministic, reliable, and proven at scale in high-volume repeatable tasks.
AMRs (Autonomous Mobile Robots) use onboard sensors (LiDAR, depth cameras, IMU) to build a map of the environment and navigate dynamically — they replan around obstacles, share dynamic paths with peers, and adapt to layout changes without re-tape-laying.
AGVs win on deterministic throughput in stable layouts; AMRs win on flexibility and faster deployment in changing environments.
Navigation and infrastructure
AGV: needs floor preparation (tape, wires, QR codes). Layout changes require re-laying the path infrastructure. Strong in environments where the layout is fixed and throughput is predictable.
AMR: needs a clean-floor scan during commissioning, plus charging stations. Layout changes handled by re-mapping (minutes to hours, not weeks). Strong in environments where workflows or layouts shift over time.
Throughput, cost and TCO
AGV: capital cost per unit can be higher for tugger / lifting vehicles, but lifetime TCO is well-understood and predictable; high-throughput applications (kitting, line replenishment, finished-goods buffer) are AGV's traditional strong suit.
AMR: faster deployment, lower per-unit capex on lighter-duty vehicles, but software, integration, fleet management and traffic-control engineering add cost. Payback is usually faster on AMR for variable workflows; AGV wins on steady high-volume routes.
Vendor landscape
AGV: JBT, Dematic, Daifuku, KION (Linde / Dematic / STILL), Toyota Material Handling, Egemin. Fork-truck-shaped AGVs from forklift OEMs are mainstream.
AMR: Mobile Industrial Robots (MIR, KION-owned), Geek+, OTTO Motors (Rockwell), Locus Robotics, Fetch (Zebra), Vecna Robotics, 6 River Systems (Shopify). The market consolidated rapidly post-2020 with major industrial groups acquiring AMR vendors.
VDA 5050 — the interoperability standard
VDA 5050 is the interface standard between mixed-fleet AGVs/AMRs and a master control system, published by the German Association of the Automotive Industry. It's now broadly adopted across European and growing North American deployments.
With VDA 5050, you can run a heterogeneous fleet — AGVs from one vendor, AMRs from another — under a single orchestration layer. This dramatically de-risks vendor commitment and enables phased rollout. See /solutions/fleet-orchestration.
Hybrid fleets and when each fits
Mature deployments often layer both. AGV for high-volume repeatable trunk routes (line-side replenishment, finished-goods buffer to dispatch).
AMR for variable goods-to-person picking, ad-hoc moves, and routes that change with seasonality or product mix. VDA 5050 binds the fleet under one master control. We pick the right vehicle for the right route in stage 1 — see /solutions/fleet-orchestration.
Frequently asked questions
Which is cheaper — AGV or AMR?
Depends on workflow. AMR is typically cheaper to deploy initially (no floor prep, faster commissioning); AGV has lower lifetime TCO on stable high-throughput routes. The right comparison is total-cost-per-completed-move over the deployment lifetime.
Can AGVs and AMRs share a master control system?
Yes — VDA 5050 is designed exactly for this. We design VDA 5050-compliant master control as part of /solutions/fleet-orchestration.
Do AMRs need WMS integration to be useful?
Yes — for any production deployment beyond proof-of-concept. AMR fleet management software integrates with WMS (SAP EWM, Manhattan, Blue Yonder, Körber) via standard APIs. We design integration patterns in stage 1.
Will AMRs replace AGVs over time?
Partly. AMR market share is growing fast in goods-to-person picking and variable workflows. AGVs retain advantages in deterministic high-volume trunk routes and heavy-load tugger applications. We expect mixed-fleet, VDA 5050-orchestrated to be the long-term answer.
How accurate is AMR navigation in practice?
Position accuracy ±2–5 cm in typical SLAM-mapped environments. Docking and load-handling accuracy is higher (mm-level) using fiducial markers at pickup points. Accuracy is bounded by sensor quality and mapping discipline.
