AGV is a vehicle, AMR is a robot.

Let's take a closer look at the differences between AGVs and AMRs.

See the table below.

  AGV AMR (Next-Generation AGV)
Navigation method Guided navigation (requires guide) Autonomous navigation (no guide required/guideless)
Range of movement Fixed route Autonomously calculated route
Collaboration with people Improper Possible
Dealing with obstacles Stop Avoiding, rerouting

Navigation method

The biggest difference between AGVs and AMRs is in the navigation method. This difference is the distinction between and definition of AGVs and AMRs.

● AGV

AGV is an abbreviation for automated guided vehicle. It is also called a self-guided vehicle or automatic guided vehicle. JISD6801 defines an AGV as "a vehicle that has the function of automatically traveling in a certain area and transporting goods other than humans such as loads, and is not used on roads stipulated by the Road Traffic Act." Its definition is still a vehicle.

● AMR

Among AGVs, those that do not require guide like magnetic tape (guideless) and estimate their own position based on information from built-in sensors are generally called AMRs (autonomous mobile robots). They are also called a guideless AGV and next-generation AGV. It may be considered that the concept of a vehicle that runs within a predetermined condition has evolved into a robot that moves by its own judgment.

Range of movement

Due to the difference in navigation method between AGVs and AMRs, there is a difference in the range of movement as well.

● AGV

As mentioned above, AGVs travel a fixed route set by guides such as magnetic tape. Therefore, it is impossible to navigate in a place where no guide is installed, and if there is an obstacle on the fixed route, it will stop and cannot navigate further. In order for them to move smoothly without any trouble, it is essential to secure a place with no obstacles and install guides.

● AMR

On the other hand, AMRs travel on a route that they autonomously calculate according to the surrounding environment. Therefore, even if there are people or obstacles on their routes, they can handle the situation by avoiding them or slowing down. Since there is no need to install guides such as magnetic tape (guideless), it is easy to change the destination, and it can be changed according to the situation. This makes it possible to deploy these robots in new places where no AGVs have ever been deployed before.

* The differences between AMRs and AGVs that have been explained so far are summarized in the figure again.

Difference between AMR and AGV

AMR is a robot developed to work with humans.

Collaborative work with people

The development concept of AGVs and AMRs is also very different.
In contrast to an AGV, which is a vehicle that simply "carries things from point A to point B," an AMR is essentially a robot that "carries things in a place that it shares an operating range with people."
An AMR has the great advantage of being able to build a "relationship in which humans and robots complement each other."
Due to this difference, an AMR is not a variation of AGVs, but it can be regarded as a completely new existence that is different from AGVs starting from the design concept up.

Did you understand the differences between AGVs and AMRs? One is a vehicle and the other is a robot. Even if they look the same, what they are is completely different.
