AGV & AMR Solutions for Material Handling

Driverless vehicles and autonomous mobile robots that move material across your plant — bundles, pallets, totes, carts — without human pushers, without wasted trips, without line-side wait time.

What is mobile robotics

Mobile robotics replaces forklifts, hand-pushed trolleys, and runner staff with vehicles that drive themselves between fixed points in your plant. They run 24/7, don't take breaks, log every trip, and free your team for higher-value work. There are two families — AGV (fixed-path, mature, cheaper) and AMR (free-navigation, flexible, more expensive). Picking the right one comes down to how often your routes change.

AGV vs AMR

How they differ

Both move things around your plant without a driver. The difference is how they decide where to go. AGVs follow fixed cues on the floor. AMRs map the space and decide for themselves.

AGV

Automated Guided Vehicle

Driverless vehicle that follows a fixed path — magnetic tape, QR codes, or reflectors on the floor. Proven, low-risk, cost-effective when your routes are stable.

AMR

Autonomous Mobile Robot

Mobile robot with LIDAR + SLAM. Builds its own map of the space and navigates dynamically — around people, around obstacles, with no floor markings.

AGV types

Four common form factors

The right AGV depends on what you're moving and how it's loaded. Tugger and unit-load cover most factory moves; forklift AGVs handle warehouses; conveyor-top fits high-speed packing lines.

Forklift AGV with stabiliser pad
01

Tugger AGV

Pulls a train of carts behind it — best for milk-run style material delivery between cutting / production / dispatch.

Garment bundle delivery · paper-roll movement · multi-stop part feeding
02

Unit-Load AGV

Carries one pallet, tote, or bin on a flat deck. Loaded by conveyor handoff or scissor-lift.

Pallet movement · finished-goods to dispatch · WIP buffer transfers
03

Forklift AGV

Same form factor as a manual reach truck or counterbalance forklift, but driverless. Handles racks and pallet stacks.

Warehouse put-away and pick · cold storage · heavy-pallet movement
04

Conveyor-Top AGV

Flat-top with powered rollers or belt on the deck. Auto-loads and auto-unloads at fixed stations.

Carton movement between packing lines · automated assembly lines
01

Free-Navigation AMR

LIDAR + SLAM lets it map any indoor space and route dynamically around people and obstacles.

Mixed-traffic factory floors · hospitals · open-plan warehouses
02

Goods-to-Person AMR

Lifts and carries entire shelving units to a picking station — operator stays put, robot brings the work.

E-commerce fulfilment · spare-parts warehouses · returns processing
03

Mobile Manipulator

AMR base with a robot arm bolted on — can drive AND pick / place at the destination.

Machine tending across multiple CNCs · lab automation · research cells
AMR types

Three primary categories

AMRs are typically classified by what they carry and what task they perform — straight transport, shelf-lifting fulfilment, or carrying a manipulator arm for point-of-use tasks.

Navigation

How robots know where to go

The single biggest design choice is how the vehicle locates itself. Below are the methods we use, ranked from simplest to most flexible.

01

Magnetic Tape

AGV

A 2-inch magnetic strip stuck to the floor. AGV follows it via magnetic sensor. Cheapest install, easiest to re-route by lifting tape.

02

QR Codes / Floor Markers

AGV

Grid of QR codes printed on the floor. Onboard camera reads them for position fix. Excellent accuracy at low cost.

03

Reflectors / Laser Triangulation

AGV

Reflective strips on walls + rotating laser scanner on the AGV. Common in older AGV installs and port environments.

04

LIDAR + SLAM

AMR

On-board LIDAR builds and maintains a live map. Robot localises itself within that map. Allows free navigation.

05

Visual SLAM

AMR

Cameras + AI replace LIDAR. Cheaper hardware, more compute-heavy, sensitive to lighting changes.

Components

What's in a mobile robot

Whether AGV or AMR, every deployment is built from the same six layers — chassis, sensors, controller, fleet software, charging, and integration with your existing plant systems.

01

Drive Chassis

Differential, omni-wheel, or steered-wheel base sized for your payload, aisle width, and turn radius.

02

Safety Sensors

Class 3 safety LIDAR around the perimeter, contact bumpers, emergency stops, and audible warnings.

03

Onboard Controller

Industrial PC running navigation, mission control, and fleet-comms. ROS / Linux or vendor-proprietary.

04

Fleet Management Software

Central server that assigns missions, prevents collisions between robots, and reports KPIs. Talks to your WMS or MES.

05

Charging Infrastructure

Contact or wireless docks. Robots auto-return to charge when battery drops below threshold.

06

Integration Layer

PLC handshakes for door openers, conveyor calls, lift access, and MES/WMS sync.

Where it fits

Industries we serve

Mobile robotics replaces material-handler runs across most industrial settings. The pattern is the same — fixed start and end points, repeatable trips, more value for the operator than pushing carts.

Manufacturing

Move raw material to work cells, WIP between stations, and finished goods to packing. Reduce material-handler headcount and eliminate wait time on the line.

Warehousing & 3PL

Goods-to-person picking, replenishment, putaway, returns. Pair AGVs with fixed conveyors for hybrid throughput.

Textile & Garment

Cutting room to sewing lines, sewing to trim/QC, finished to dispatch. Tugger AGVs pull bundle trolleys on a milk-run schedule.

FMCG & Beverage

Pallet movement from production to staging, full-pallet load-out, cold-room access via forklift AGV.

Pharma & Healthcare

Sample and meal delivery in hospitals, sterile material handling in pharma plants, regulated paths with full audit logs.

Ports & Heavy Industry

Container movement, heavy-load shuttles between yard and dock — the original AGV use case.
