AMR vs AGV vs Cobot: A Plain-English Guide for UK Businesses
Clear, plain-English definitions of autonomous mobile robots, automated guided vehicles and collaborative robots — and where each one belongs in a UK operation.
Quick answer
AMRs (autonomous mobile robots) navigate freely using sensors and an onboard map and are the right pick for changing UK warehouse and hospitality environments. AGVs (automated guided vehicles) follow fixed routes via tape, wires or magnets and suit large, stable, high-throughput sites. Cobots (collaborative robots) are fixed-position robot arms designed to work safely alongside people on bench tasks such as assembly, inspection or packing.
Three terms come up on almost every first call: AMR, AGV and cobot. They get used interchangeably and they should not be. They describe different machines, different deployment models and different commercial cases. This is the plain-English version, written for UK operators who want to choose the right one without wading through technical brochures.
What is an AMR (autonomous mobile robot)?
An autonomous mobile robot is a mobile platform that navigates freely using onboard sensors — typically LiDAR and 3D cameras — and a software map of the building. It does not need tape on the floor, wires under the surface or QR markers on the wall. It picks its own path, reroutes around obstacles, and updates its understanding of the environment as it operates. Service robots, delivery robots and modern internal-transport robots are almost all AMRs.
Where AMRs fit
- Hospitality — restaurants, hotels and care homes where layouts change and people move freely
- Healthcare — meal, linen and consumables delivery between wards or floors
- Distribution and fulfilment — internal transport between picking, packing and despatch zones
- Retail and cleaning — floor cleaning, shelf scanning and back-of-house movement
What is an AGV (automated guided vehicle)?
An automated guided vehicle follows a fixed, pre-installed path — magnetic tape, an inductive wire under the floor, painted lines or a QR code grid. It does not pick its own route and it cannot meaningfully reroute around obstacles other than stopping. AGVs are typically used in large, stable, high-volume manufacturing and distribution sites where the route does not change for months or years.
Where AGVs fit
- Heavy-volume manufacturing lines with fixed material flows
- Large distribution sites running the same loop every shift, every week
- Closed environments where humans rarely cross the AGV's path
What is a cobot (collaborative robot)?
A collaborative robot is a fixed-position robotic arm designed to work safely in the same physical space as people. Cobots have force-limited joints and onboard safety sensors so they slow or stop when a person enters their working envelope. They are not mobile — they sit on a bench or a frame and perform a repetitive task in front of them.
Where cobots fit
- Light assembly and machine tending
- Inspection and quality checks
- Packing, palletising and end-of-line tasks
- Lab and life-sciences pipetting and sample handling
AMR vs AGV vs cobot — side by side
| Factor | AMR | AGV | Cobot |
|---|---|---|---|
| What it is | Mobile robot that navigates freely | Mobile vehicle on a fixed path | Fixed-position robot arm |
| Navigation | Onboard sensors + software map | Tape, wire, QR or magnetic markers | Not mobile — works in front of itself |
| Reroutes around obstacles | Yes | No — stops and waits | N/A |
| Installation effort | Low — software map only | High — floor markers or wires | Low — bench mount and safety zone |
| Best-fit environment | Changing layouts, people present | Stable, high-volume, low-people zones | Bench tasks alongside people |
| Typical UK sectors | Hospitality, care, retail, fulfilment | Heavy manufacturing, large DCs | Assembly, inspection, life sciences |
| Flexibility | High — re-map at any time | Low — fixed to installed path | Medium — reprogram for new tasks |
Which one is right for your operation?
For most UK hospitality, care, retail and modern distribution operations, the answer is an AMR. The combination of free navigation, low install effort and ability to coexist with people fits the way these buildings actually run. AGVs still win in high-volume, stable manufacturing where the cost of installing a fixed path is justified by years of unchanged use. Cobots are the right answer for bench-based repetitive work — not for moving items around a building.
What buyers should ask before committing
- Does my building layout change month to month?
- Do humans share the floor with the robot, or is it a fenced zone?
- Do I need the robot to move items, or operate on a fixed task?
- What is the cost and disruption of installing fixed-path infrastructure?
- Who supports and maintains the robot in the UK, and at what response time?
Frequently asked questions
- What is the difference between an AMR and an AGV?
- An AMR navigates freely using onboard sensors and a software map, so it can reroute around obstacles and adapt to changing layouts. An AGV follows a fixed path defined by tape, wires, magnets or QR markers and stops when something blocks it. AMRs suit changing UK operations; AGVs suit stable, high-volume flows.
- Is a cobot the same as an AMR?
- No. A cobot is a fixed-position robotic arm designed to work safely alongside people on bench tasks such as assembly, packing or inspection. An AMR is a mobile platform that moves around a building. They solve completely different problems.
- Are service robots AMRs?
- Yes — modern commercial service, delivery and cleaning robots are AMRs. They navigate freely using LiDAR and 3D cameras, follow a software map of the venue, and reroute around guests, staff and obstacles without needing tape on the floor.
- Do AMRs need infrastructure installed in the building?
- No fixed infrastructure is required. AMRs need power for the charging dock, network coverage (Wi-Fi or 4G) for fleet management and software updates, and access to lifts where required — but the navigation map is software-only.
- Which is cheaper to deploy in the UK — an AMR or an AGV?
- AMRs are usually cheaper to deploy because there is no floor infrastructure to install. AGVs can be cost-effective at very high volumes once the fixed-path install is amortised, but the upfront installation, building disruption and inflexibility are significant.
- Can AMRs and cobots work together in the same operation?
- Yes. A common UK pattern is an AMR moving totes between zones and a cobot performing a bench-based task such as packing or quality inspection. The AMR brings work to the cobot's bench and removes finished work.
- Where do AGVs still make sense in 2026?
- Stable, high-volume manufacturing and large-scale distribution sites running the same loop every shift, with limited human traffic on the route, are still strong AGV environments. Anywhere the layout changes or humans share the floor is usually a better AMR fit.
