Autonomous Mobile Robots Types

Types of Autonomous Mobile Robots (AMRs): The Complete Guide for Factories & Warehouses

Autonomous Mobile Robots (AMRs) have become one of the most transformative technologies in modern intralogistics. As factories and warehouses push toward higher efficiency, safer operations, and Industry 4.0 readiness, AMRs are now replacing manual material movement at scale.

Yet with dozens of AMR variants available today, one question often causes confusion:

“What are the different types of AMRs — and which one is right for my facility?”

This comprehensive guide breaks down every major AMR category, how each one works, where it fits best, and how to choose the right type for your application.

What Are AMRs? A Quick Refresher

AMRs (Autonomous Mobile Robots) are intelligent, self-navigating robots equipped with sensors, 2D/3D LiDAR, cameras, and AI-based algorithms that help them understand their environment, avoid obstacles, and move safely inside factories and warehouses — without requiring physical guidance infrastructure.

Unlike AGVs (which follow fixed paths), AMRs dynamically plan routes, bypass blockages, and adapt to daily operational changes.

What Are the Main Types of AMRs? (Quick Answer)

There are eight widely used AMR categories in industrial settings:

  1. Forklift AMRs
  2. Pallet Truck AMRs
  3. Tugger AMRs
  4. Conveyor-Top AMRs
  5. Shelf-Carrying AMRs (Goods-to-Person)
  6. Sorting AMRs
  7. Collaborative AMRs
  8. Custom/Hybrid AMRs

Each type is engineered for a specific intralogistics challenge — from pallet movement to goods picking, kitting, sortation, line-side replenishment, and full-facility automation.

Here is the detailed breakdown.

  1. Forklift AMRs (Autonomous Forklifts)

What They Do

Forklift AMRs autonomously lift and transport pallets from ground level to height — including racks, conveyors, and flow stands.

Key Capabilities

  • Lift height: 2m to 6m+
  • Payload: 1,000–2,500 kg
  • Pallet detection using 3D vision
  • Millimeter-accurate positioning
  • Compatible with high-bay storage

Where They Fit Best

  • Receiving → storage putaway
  • Storage → production replenishment
  • High-density warehouses
  • Automotive and FMCG distribution
  • Multi-shift operations

Why Choose a Forklift AMR

  • Eliminates manual forklift dependence
  • Perfect for tall racking environments
  • Consistent, safe pallet handling
  1. Pallet Truck AMRs (Ground-Level Pallet Movement)

What They Do

Move pallets at ground level between production zones, staging areas, conveyors, QC, dispatch, and storage.

Key Capabilities

  • Payload: 1,000–2,000 kg
  • Ground-level transport only
  • Compact design for narrow aisles
  • Fast acceleration for short routes

Where They Fit Best

  • Production line feeding
  • Receiving → inbound QC
  • Finished goods movement
  • Cross-department pallet flow

Why Choose a Pallet Truck AMR

  • Most common AMR type
  • Ideal for fast, repetitive, short-distance movement
  • Great for both factories and warehouses
  1. Tugger AMRs (Towing Robots)

What They Do

Pull multiple carts/trolleys in a “train” configuration across the facility.

Key Capabilities

  • Towing capacity: 500 kg to 3,000 kg
  • Automated hitching/unhitching
  • Supports long, multi-stop routes

Where They Fit Best

  • Automotive kitting
  • Milk-run replenishment
  • Multi-SKU movement
  • WIP (work-in-progress) transfer
  • Gemba-style assembly flows

Why Choose a Tugger AMR

  • Highest throughput per robot
  • Ideal for multi-station deliveries
  • Great for takt-based manufacturing
  1. Conveyor-Top AMRs

What They Do

These AMRs have conveyor belts mounted on top to transfer bins, totes, or cartons automatically.

Key Capabilities

  • Bi-directional conveyor movement
  • Seamless transfer to fixed conveyors
  • Ideal for lights-out transport

Where They Fit Best

  • Packaging lines
  • Finished goods transfer
  • Automated storage systems
  • E-commerce sortation

Why Choose Conveyor-Top AMRs

  • Eliminates manual tote transfer
  • Perfect for “conveyor gap” automation
  • Smooth integration with AS/RS
  1. Shelf-Carrying AMRs (Goods-to-Person Systems)

What They Do

Lift entire shelving units and bring inventory to stationary picking stations — transforming warehouse picking productivity.

Key Capabilities

  • Carry 300–1,000 kg shelving pods
  • Real-time inventory slotting
  • 3–4× increase in picker productivity

Where They Fit Best

  • E-commerce fulfillment centers
  • Spare parts warehouses
  • Health & pharma distribution
  • Any operation with 1,000+ SKUs

Why Choose Shelf-Carrying AMRs

  • Minimizes worker walking time
  • Enables high-density storage
  • Delivers maximum order picking speed
  1. Sorting AMRs (Parcel / Tote Sortation)

What They Do

Identify, route, and sort parcels or totes to designated zones or chutes.

Key Capabilities

  • Up to 1,000 items/hour per robot
  • Built-in barcode/QR scanning
  • AI-based dynamic sorting

Where They Fit Best

  • Courier and parcel hubs
  • E-commerce returns
  • Cross-dock operations
  • 3PL distribution centers

Why Choose Sorting AMRs

  • Fastest way to scale sortation without conveyor systems
  • Great for peak season handling
  1. Collaborative AMRs (CoBots on Wheels)

What They Do

Share working spaces with humans and support them in movement-heavy tasks.

Key Capabilities

  • 360° safety sensors
  • Dynamic speed adaptation
  • Configurable payload platforms

Where They Fit Best

  • Mixed-traffic environments
  • Factories with manual sub-assembly
  • Operations needing safe human-robot coexistence

How to Choose the Right AMR Type

Ask these questions:

  1. What are you moving?

Pallets → Forklift or Pallet Truck
