AMR vs. AGV: What’s the difference?

What do AGV and AMR stand for?

AGV – Automated Guided Vehicle: A guided vehicle designed to transport materials along a set path via tracks, wired connection, or magnetic tape.

AMR – Autonomous Mobile Robot: An independent robot that navigates its environment using advanced sensors and mapping technology (no set paths required).

The main difference

The primary difference is that AGVs operate via guided pathways and set navigation, while AMRs offer a more agile solution that can navigate dynamic environments with minimal to no modification to your building.

AGV vs. AMR: Which one is best for you?

AGVs: They’ve existed for decades when it comes to automated material handling. They’re best used in a large material handling world with a consistent and unchanging production setup. Companies can invest in infrastructure development for AGVs, but it typically incurs an expensive upfront cost when they must lay physical groundwork for tracking systems. They don’t always pivot well when production needs change.

AMRs: They’re new and evolving! With LiDAR, cameras, and AI-empowered navigation, they can create maps and determine paths on the go. AMRs navigate their real-time environments to find the fastest path without human intervention, making them incredibly efficient in rapidly changing production environments.

Set path vs. smart movement

• AGVs: Operate on set paths with predetermined tracks and movement inputs. They utilize magnetic strips or QR codes to direct them. If you need them to take a different route, you will have to spend extensive time and money on reinstallation. They stop if they hit obstacles and cannot find alternative routes.
• AMRs: Operate via sensors, cameras, and mapping abilities. They acknowledge obstacles in their path and adjust their course on the fly.

Flexibility versus function

• AGVs: Best for repetitive tasks that don’t change. Once established, they’re hardwired for life with a consistent purpose unless grossly changed (and that’s expensive).
• AMRs: Flexible! They can perform similar transport tasks across multiple areas, which are effectively managed via software or fleet management. This benefits companies whose layouts change regularly.

Business model: established vs. changeable

• AGVs: Fit businesses operating under traditional models where things don’t change, and layouts remain the same. They rely on stability and infrastructure developments.
• AMRs: Created for agile business scenarios. If your production line moves or expands, an AMR can be reprogrammed or given a new map with established points to follow so your production remains stable.

Safety protocol

• AGVs: Operate with basic obstacle awareness. When they hit something, they usually stop until the object is removed.
• AMRs: Use LiDAR, 3D cameras, and effective ISO navigation standards to detect potential obstacles in real-time. They slow down or reroute depending on what’s in their way.

Cost and ROI

• AGVs: Require a hefty initial investment due to the necessary infrastructure. Even when established, additional costs may arise if routes or functions need to be realigned.
• AMRs: Deploy quickly with a relatively low investment cost due to the absence of fixed infrastructure requirements. They provide efficiency almost immediately, within weeks of deployment, providing ROI in a few short months.
