AMRs and AGVs for Factories and Warehouses

Autonomous Mobile Robots (AMRs) and Automated Guided Vehicles (AGVs) automate material movement — from raw stock to machine, finished goods to shipping. This guide explains the real differences, costs, and when each type is right.

Key points

  • AMRs navigate autonomously and reroute around obstacles; AGVs follow fixed paths and stop when blocked
  • AGVs cost less upfront ($20,000–$80,000) but require floor modification; AMRs cost more ($40,000–$150,000) but deploy faster
  • For facilities with changing layouts or mixed pedestrian/vehicle traffic, AMRs are generally more practical
  • Mobile manipulators (AMR + robot arm) allow one unit to service multiple fixed workstations — high complexity, high potential ROI
  • Fleet sizing rule of thumb: one AMR per material move that currently occupies a person more than 2 hours per shift

Frequently asked questions

How many AMRs does a factory need?
Start by mapping all material moves currently done by forklifts or manual carts: route distance, frequency, payload, shift coverage. An AMR carrying 500 kg at 1.5 m/s can typically complete a 100 m round trip in about 2.5 minutes. If you have a move that requires 30 trips per shift, one AMR handles it with some margin. Add 20–30% fleet overhead for charging, queueing and maintenance. Most factory deployments start with 1–3 AMRs and scale from there.
Do AMRs require a Wi-Fi infrastructure upgrade?
Usually yes. AMRs communicate with fleet management software via Wi-Fi; patchy coverage causes navigation failures and lost updates. Industrial Wi-Fi (802.11ac/ax) with overlapping access points is recommended. Most AMR vendors provide a coverage checklist and will specify the AP placement. Budget $5,000–$20,000 for Wi-Fi infrastructure improvements in a typical factory deployment.
Can an AMR navigate in a facility with forklifts?
Yes, but with careful zoning and traffic management. AMRs slow and stop for detected obstacles (including forklifts), but forklift operators may not yield reliably. Best practice: separate AMR corridors where possible, define AMR-priority zones with floor markings, and train forklift operators on AMR behaviour. Most AMR vendors offer fleet management software that can coordinate AMR routes with known forklift traffic patterns.
What is the safety standard for AMRs in factories?
ISO 3691-4 covers industrial trucks — including driverless vehicles — and defines performance and test requirements. ANSI/ITSDF B56.5 covers safety of driverless automatic guided industrial vehicles in the US. AMRs must also comply with machinery safety (ISO 12100, ISO 13849) for their protective functions. Check your specific AMR vendor's safety certifications before deployment.
