AGV vs AMR : voie fixe ou auto-navigation ?

An AGV (Automated Guided Vehicle) follows a preset fixed route on magnetic strips, QR codes or floor tracks; an AMR (Autonomous Mobile Robot) senses the environment with LiDAR and plans its own route in real time - the difference is whether it can find its own way.

Quel problème cela résout

Factory material delivery, garage cleaning and campus patrols all need robots to move things, but routes change: lines expand, goods pile up temporarily, weekend routines shift. Rerouting an AGV means re-laying strips or editing programs. An AMR maps once, and you draw a new path on the map; when it meets a person, it simply goes around.

Picking wrong is costly: heavy industrial transport with unchanged routes for ten years suits a cheap, tough magnetic AGV. Frequent route changes and human-mixed traffic on an AGV mean daily blockages.

Comment lire les spécifications clés

AGV navigation method: magnetic strip is cheapest but costly to reroute; QR codes are accurate but need stickers everywhere; laser guidance sits between the two.
AMR repeatability: mm-level alignment at charging docks and workstation docks decides whether unattended operation is possible.
Fleet scheduling: when multiple robots run together, whether the dispatcher avoids congestion, yields and resolves deadlocks matters more than single-robot specs.
Speed range: AGVs are generally slow; indoor AMRs run 0.5-1.5 m/s, outdoor patrol robots over 1.5 m/s.

Idées reçues courantes

Misconception 1: AMR always replaces AGV. For heavy transport with unchanged routes for a decade, a magnetic AGV needs almost no care; AMR sensors and algorithms add failure points.

Misconception 2: calling it AMR makes it truly autonomous. Some "fake AMRs" only follow pre-laid paths and stop for help when blocked - they are just obstacle-aware AGVs.

Misconception 3: navigation method decides payload. Navigation decides whether it finds its way; payload is decided by chassis structure and wheel diameter.

Modèles recommandés

Tbot-N5-3D is a typical AMR chassis: single 3D multi-line LiDAR autonomous navigation, 100-500kg payload, replacing magnetic-strip AGVs for line-side material delivery; light-load use cases see the light AGV/AMR line. Compare parameters in the full spec table.
