What is the difference between indoor unmanned material handling and AGV/AMR?

1. The three are not at the same level

Indoor unmanned transportation

It is more like a general term for the application layer and system layer, referring to the automatic handling of materials, goods, and tooling in indoor environments through unmanned equipment and systems.

It is not a single device, but a complete set of solutions.

AGV (Automated Guided Vehicle)

It is a specific equipment form for achieving indoor unmanned transportation, relying on "predetermined paths" for operation.

AMR (Autonomous Mobile Robot)

It is also a transport equipment, but it possesses stronger environmental perception and autonomous decision-making capabilities, and its operation mode is more flexible.

Simple understanding:

Indoor unmanned handling = target and system

AGV / AMR = different technical routes to achieve this goal

II. Differences in Navigation Methods: Core Watershed

1. AGV: Follow the "prescribed route"

AGVs typically rely on one of the following methods for navigation:

Magnetic strip, magnetic pin

Ground QR code

Track or reflective strip

Laser reflector (laser navigation AGV)

The characteristics are:

Plan the route in advance

The driving path is relatively fixed

"More like an 'autonomous vehicle'"

Advantages

"Technology is mature"

High stability

Behavior is predictable

Limitations

Once the route is changed, the cost of reconstruction will be high

It has a significant dependence on the on-site environment

2. AMR: "Learning the way" and "avoiding the way" by itself

AMR typically adopts:

Laser SLAM

Visual SLAM

Multi-sensor fusion (laser + camera + IMU)

It does not rely on a fixed path, but rather:

Build a map through perceiving the environment

Real-time determination of the optimal route

"Encountering obstacles, one can take the initiative to bypass them."

Advantages

Flexible deployment

Adapt to dynamic environment

"Relocation does not require construction."

Limitation

The system has higher complexity

High requirements for algorithms and computing power

There are certain requirements for environmental stability

III. Different adaptability to environmental changes

IV. System level: Indoor unmanned handling focuses on "overall efficiency"

A true indoor unmanned handling system usually also includes:

Scheduling system (task allocation, path planning)

Interface integration with WMS / MES / ERP

Multi-vehicle coordination and traffic management

Charging, standby, and exception handling strategies

At this level:

AGV is more like an "execution terminal"

AMR is more like a "smart node"

But no matter which one is chosen, the core is not the vehicle, but whether the system matches the on-site process.

V. Differences in Typical Application Scenarios

AGV is more commonly seen in:

Automobile manufacturing production line

Battery and electronic assembly line

Fixed route transportation from production line to production line

Heavy-load and pallet handling

AMR is more common in:

Warehouse picking

Hospital material distribution

Multiple SKUs and multiple locations for handling

Human-machine collaboration scenario

6. When selecting, don't just ask "Should I use AGV or AMR?"

The more important question is actually:

Is the route on site fixed?

Is it necessary to frequently adjust the workstation?

Are personnel and equipment moving together?

Is there a need for a quick launch with minimal modification?

Has future expansion been considered?

In many projects, AGV and AMR can coexist within the same indoor unmanned handling system, each performing its own specific function.
