Before you order an AMR — design the charging and parking zones
Mobile robot uptime is no longer a technical detail — it has become one of the most important operational KPIs on the shop floor. Before you spend your budget on an AMR, it is worth designing its surroundings — and the element most often overlooked is well-planned AMR charging zones and parking areas. These are what determine how many real working hours you can get out of the fleet and whether the robots will start blocking people, trucks and picking routes.
The warehouse robotics market is shifting its emphasis ever more clearly from autonomy itself to continuity of operation. Dexory is developing robots designed for near-continuous operation, and the company is backed by more than USD 100 million in funding — a sign that the topic of uptime and energy management is maturing commercially, not just technologically. The conclusion for your hall is simple: if a robot is to work without a break, the break for charging must be designed as carefully as the travel route.
Why AMR charging zones determine the return on investment
Manufacturers state a robot's parameters under model conditions: a full cycle, smooth travel, no collisions. On a real shop floor, these conditions are spoiled by the surroundings — and especially by what happens between tasks. A robot that has to travel to a charging point "somewhere off to the side" after each cycle covers extra metres, enters mixed pedestrian and truck routes, and waits for a free space. Every such minute is a drop in uptime that you will not see on the datasheet.
A well-planned charging and parking area works the other way round: it shortens empty runs, eliminates robots queuing and removes the points where the fleet comes into conflict with people. This is not a question of layout aesthetics — it is a direct multiplier of machine availability. So before you compare suppliers' quotes, check whether your hall has room for energy at all.
Three things to design before buying
1. Charging and parking areas built into the flow
A charging point cannot be treated like a socket stuck on a wall. It must be built into the real material flow so that the robot reaches it by the shortest route without blocking people, trucks or picking routes. In practice, this means three decisions: where to designate the parking zones, what safety buffer to leave around the station, and how to describe the rules for entering and leaving so that two robots do not "meet" at the same bottleneck.
It is worth marking the charging zone both physically and visually — with a high-contrast floor marking tape defining the outline of the station and the buffer, so that an operator can see from several metres away that this is an area dedicated to the machine. Then nobody will leave a pallet there "for a moment", and the robot will not find its space occupied when it returns from a cycle.
2. Separating people and AMR traffic around energy
Most problems with mobile robots do not start in the middle of the route, but at points of intersection — and the charging zone is one of the most sensitive. This is where the robot slows down, manoeuvres and stops, often in reverse, while people and trucks are moving nearby. Before you let the fleet in, check the collision points, narrow sections and places of sudden stopping within the approach radius of the chargers.
In mixed-traffic zones, physical separation is more important than any software. Where the robot's route to charging crosses a pedestrian walkway, it is worth separating the traffic with a physical barrier or bollard, not just a line on the floor. ZonePro mobile barriers, which quickly define a zone without interfering with the floor, work well here, as do permanent Raysan barriers where the collision point is fixed. There is one goal: people must immediately understand where their space ends and the machine's manoeuvring area begins.
3. Clarity of zones and traffic rules
If the set-down area and the walkway near the charger are not visually clear, chaos returns — no matter how intelligent the robot is. A clear space means fewer emergency stops, fewer operator interventions and higher uptime. The marking must also work in poorer light and between shifts, when the hall operates at a different pace.
The principle that ties everything together: a clear space means fewer stops and better uptime — and all of this starts before the robot is even bought, at the layout design stage.
Energy as part of the layout, not an add-on
The direction in which the market is heading — wireless charging, opportunity charging, near-continuous operation — is changing the way halls are planned. Until recently, a robot would travel to a single "docking station" and stay there for a long time. Today, it more often tops up briefly and repeatedly, at many points spread along its routes. This means more energy stations in the layout, and each of them must have a defined outline, buffer and approach rules.
The practical consequence is that energy is no longer a matter for the maintenance department but becomes part of the flow design. If you treat it as an add-on installed after deployment, you will pay for it with lower fleet availability and a growing number of conflicts in mixed traffic. If you design it together with the routes, the robots will top up "on the way", without empty kilometres.
Checklist: is your hall ready for AMR charging zones?
- Location: are the charging points on the robot's natural routes, rather than in dead ends that force empty runs?
- Outline and buffer: does each station have a defined area and a safety zone physically marked on the floor?
- Separation: is the approach to the charger separated from pedestrian and truck traffic at collision points?
- Approach rules: is it clear how robots enter and leave, so that two machines do not block the same bottleneck?
- Clarity: can an untrained operator understand within a few seconds that this is a robot zone, even in poorer light?
- Scalability: does the layout allow for additional energy stations as the fleet grows?
If you answer "no" to most of the questions, buying a robot will not solve the problem — it will only reveal it sooner. The order is the reverse of what intuition suggests: first you design the energy environment, then you buy the machine that is to work in it.
FAQ
Can a charging zone be defined without interfering with the floor?
Yes. The outline of the station and the safety buffer can be marked with durable floor marking tape, and the zone can be separated with mobile barriers that are repositioned as the layout changes. This is important at the pilot stage, when the route layout is still being fine-tuned and rigid infrastructure would be premature.
How many charging stations should be planned at the start?
The number depends on the fleet's work profile and the charging model adopted, so it is worth agreeing it with the robot supplier on the basis of real cycles rather than catalogue data. The design principle is constant: each station must have a defined outline, buffer and approach rules, regardless of whether you start with two or with ten.
Which is the greater threat to uptime — the battery or the layout?
Under model conditions, the battery is the limiting factor, but on a real shop floor it is most often the layout that eats into availability: empty runs to the charger, robots queuing and collisions in mixed zones. That is good news, because these particular losses can be eliminated through good space design, before the first robot even arrives.
