What Are Autonomous Mobile Robots (AMRs)? Types, How They Work, and Where They’re Used

Autonomous mobile robots (AMRs) are transforming how Singapore’s warehouses, factories, and hospitals move goods and materials.

Unlike machines bolted to a single production line, AMRs plan their own routes, avoid obstacles, and adapt in real time — all without a human driver or a fixed track.

For Singapore businesses facing rising labour costs and a tight logistics workforce, knowing what AMRs are and how they work has become a genuine competitive question, not a futuristic one.

This guide breaks down the definition, the technology inside an AMR, the main types on the market, and where they are already delivering results across Singapore’s logistics, manufacturing, and healthcare sectors.

What Is an Autonomous Mobile Robot (AMR)?

An autonomous mobile robot is a self-navigating machine that uses onboard sensors, cameras, and software to move through a space without a human steering it.

It builds an understanding of its surroundings, decides on the best path, and adjusts that path the moment something changes — a person walking past, or a pallet left in an aisle.

This is different from a fixed industrial robot arm, which repeats the same motion in the same spot. An AMR moves through the building itself.

A familiar consumer example is the robotic vacuum cleaner, which maps a room and works around furniture. Industrial AMRs use the same core idea, scaled up for warehouses, factories, and hospitals.

How Do Autonomous Mobile Robots Work?

AMRs combine three layers — sensing, decision-making, and movement — that all have to work together in real time for the robot to operate safely.

Sensing the environment

LiDAR sensors send out laser pulses to build a 3D map of the space
Cameras (RGB and depth) help the robot recognise objects and estimate distance
An inertial measurement unit (IMU) tracks the robot’s orientation and speed
Ultrasonic and infrared sensors catch obstacles that cameras might miss, such as in low light

Mapping and localisation

Most AMRs use a technique called SLAM (Simultaneous Localisation and Mapping). It continuously updates a map of the space while tracking exactly where the robot sits within it.

Planning a path

Once the robot knows where it is, path-planning algorithms such as A*, D* Lite, or RRT calculate the fastest safe route — and recalculate instantly if that route gets blocked.

Fleet coordination

In a facility with many AMRs, a fleet management system assigns tasks and prevents traffic jams, often with robots sharing data over Wi-Fi or 5G so the whole fleet moves as one.

Artificial intelligence under the hood

Computer vision models, often convolutional neural networks, let an AMR identify objects, read barcodes, and distinguish a walkway from a hazard zone.

Some AMRs also use reinforcement learning, where the robot improves its own navigation strategy over repeated runs rather than following a fixed rulebook.

Time-sensitive decisions, like an emergency stop, are typically processed on the robot itself (edge computing), while fleet-wide analytics and predictive maintenance run in the cloud.

AMR vs AGV: What’s the Difference, in Short?

The most common question business owners ask is how an AMR differs from an AGV (automated guided vehicle). The short answer is navigation.

An AMR senses its surroundings and reroutes around obstacles on its own. An AGV follows a fixed path, such as floor tape or guide wires, and generally stops when blocked.

For the full comparison — cost, ROI timelines, safety standards, and when an AGV still makes sense for your operation — see our dedicated AMR vs AGV comparison guide for Singapore warehouses.

Types of Autonomous Mobile Robots

AMRs are built for different jobs. The main categories Singapore businesses typically encounter are:

Picking robots — bring shelving units or bins to a human picker, cutting walking time in goods-to-person setups
Self-driving forklifts and pallet movers — transport heavier pallet loads across a warehouse floor
Inventory and scanning robots — patrol aisles overnight using RFID or barcode scanning to keep stock counts accurate
Delivery robots — move parcels or food over short, last-mile distances
Disinfection robots — use UV light to sanitise floors and surfaces, common in healthcare facilities
Service and hospitality robots — assist in retail, F&B, and front-of-house roles

Most Singapore deployments fall into the first three categories, since logistics and manufacturing remain the country’s biggest adopters of this technology.

Notable AMR Companies to Know

The global AMR market is crowded, but a handful of names come up repeatedly in Singapore deployments and industry reporting.

Locus Robotics, GreyOrange, and inVia Robotics — established goods-to-person picking robot makers used widely across Asia-Pacific warehouses
Mobile Industrial Robots (MiR) and OTTO Motors — manufacturing-focused AMRs for material transport between production lines
Botsync — a Singapore-based, SGInnovate-backed AMR developer reporting triple-digit production growth in 2025
ST Engineering and Addverb — regional players supplying robotics and automation systems to logistics and manufacturing clients
Boston Dynamics — known for advanced mobility robots, including package-handling units used in select fulfilment settings

At global scale, the momentum is significant: Amazon alone now operates more than one million AMR units across its fulfilment network, and the wider delivery-robot segment is projected to reach roughly US$1.8 billion in value by 2028.

Where Singapore Businesses Are Already Using AMRs

Warehousing and logistics

This is the largest use case. AMRs support goods-to-person systems, where the robot brings inventory to a stationary picker instead of the reverse.

They also work alongside automated storage and retrieval systems (ASRS), moving totes between storage and packing stations.

Manufacturing

On production floors, AMRs shuttle components and finished parts between assembly stations, reducing manual trolley runs and freeing staff for higher-value tasks.

Healthcare

Singapore General Hospital cut pharmacy wait times from around 45 minutes to under 12 minutes after automating internal medication transport, according to sector data from the Singapore Vision Robotics Centre.

Retail and e-commerce

E-commerce fulfilment centres serving Singapore’s online shopping demand use AMRs for order consolidation and rapid restocking during peak sales periods, when order volumes can spike well beyond everyday staffing levels.

Retailers running physical stores alongside online fulfilment also use scanning AMRs overnight to keep shelf and inventory data accurate for next-day operations.

Ports and supply chain

PSA International already runs more than 500 robots across its terminals, handling roughly 37 million TEUs a year. The upcoming Tuas Mega Port is designed to run with around 40% fewer workers needed per container handled.

Businesses building or upgrading their own logistics networks often pair AMRs with a wider automated supply chain management system to keep data flowing between the warehouse floor and the rest of the operation.

Key Benefits of Deploying AMRs

Higher throughput — AMRs don’t take breaks, and goods-to-person picking can cut walking time by up to 60%
Lower dependency on manual labour — a genuine advantage given Singapore’s tight logistics workforce and rising wage costs
Improved workplace safety — robots take on repetitive, heavy, or hazardous transport tasks
Faster deployment than fixed infrastructure — no need to rip up the floor or install conveyor lines
Scalability — add or reassign units as demand shifts, rather than committing to one fixed layout

These gains add up quickly: industry benchmarking generally puts AMR payback periods under six months, versus 12 to 18 months or more for a comparable AGV installation.

AMRs also complement other storage technology. Businesses running dense storage such as vertical carousel storage systems or a broader warehouse automation system often add AMRs as the “last mile” connector between storage and the packing floor.

Challenges and Limitations to Weigh

No automation decision is without trade-offs. Before committing budget, Singapore operators should consider:

Battery life and charging cycles, which affect how many hours a unit can run without downtime
Sensor interference from dust or reflective surfaces, which can affect navigation accuracy in some warehouse environments
Fleet management complexity once a deployment grows past a handful of units
Space trade-offs, since AMR aisles typically need more clearance than a dense cube-storage system
Cybersecurity, since fleet-connected robots are network endpoints that need the same protection as any other IT asset
Evolving safety standards, as regulation for human-robot collaboration continues to develop globally

Interoperability is a related concern: fleets from different vendors don’t always share data or safety protocols cleanly, which is why a fleet management layer and clear integration planning matter as much as the robots themselves.

The Singapore Market: Why Momentum Is Building

Singapore’s robotics and automation sector reached roughly S$2.1 billion in 2026, more than double its 2021 value, giving the country one of the highest robot densities in Asia.

Much of this is government-backed. The National Robotics Programme committed S$635 million between 2022 and 2025 across logistics, manufacturing, construction, and healthcare, with a further S$800 million expected under NRP 2.0 from 2026.

Local businesses can also draw on the Productivity Solutions Grant (PSG) and Enterprise Development Grant (EDG) to offset automation costs, alongside IMDA’s AI and Robotics Accelerator, which has provided up to S$500,000 in non-dilutive funding to qualifying projects.

More than 2,400 SMEs have already used EnterpriseSG co-funding for automation projects since 2023, and SkillsFuture has retrained over 50,000 workers in robot operation and maintenance. The direction of travel is clear.

How to Choose the Right AMR for Your Business

Before selecting hardware, work through these questions:

How variable is your workload? Fluctuating volumes suit AMRs better than a fixed conveyor line.
What does your floor plan look like? Narrow aisles, uneven flooring, or patchy Wi-Fi coverage can limit certain models.
What systems does it need to talk to? Your AMR should integrate cleanly with your existing WMS or ERP software.
What’s the realistic payback period? Compare upfront cost against labour savings and throughput gains over 12–24 months.
Who supports it locally? Local servicing, spare parts, and technical support matter once the robot is on your floor daily.

Working through this checklist with a local systems integrator, rather than a hardware vendor alone, tends to produce a better long-term fit. Goshen International’s robotics and automation services team works through exactly this process with Singapore businesses, from initial assessment to integration and ongoing support.

FAQ: Autonomous Mobile Robots

What is an autonomous mobile robot (AMR)?

An AMR is a self-navigating robot that uses sensors and software to move through a space and complete tasks without a human driver or a fixed track.

What’s the difference between an AMR and an AGV?

An AMR senses its surroundings and reroutes around obstacles on its own. An AGV follows a fixed path, such as floor tape or guide wires, and typically stops when blocked.

How much do autonomous mobile robots cost?

Prices range from a few thousand to tens of thousands of dollars per unit, depending on payload capacity, sensor quality, and software features. Fleet size and integration work add to the total cost.

Are AMRs safe to use around people?

Yes, when properly specified and maintained. AMRs use obstacle detection and automatic stopping to operate near people, though businesses should still follow local workplace safety guidance for human-robot collaboration.

What government support is available for AMR adoption in Singapore?

Several grants and accelerator programmes currently support automation projects in Singapore. See our AMR vs AGV guide for Singapore warehouses for the full, up-to-date list of schemes and eligibility.

Which Singapore industries benefit most from AMRs?

Logistics and warehousing see the fastest returns, followed by manufacturing and healthcare. Port operations and last-mile delivery are also growing use cases locally.

How long does it take to deploy an AMR system?

A single-zone pilot can often go live within a few weeks. A full multi-zone fleet rollout, including WMS integration and staff training, typically takes a few months.

Conclusion

Autonomous mobile robots are no longer an experimental technology. They are an established, increasingly affordable way for Singapore warehouses, factories, and hospitals to move materials faster and more safely.
