Introduction
When businesses first start exploring warehouse robots, one of the practical questions that often comes up is:
“Do warehouse robots need Wi-Fi to work?”
The answer depends on the robotic system and how it has been configured.
Many modern warehouse robots use a wireless network to communicate with fleet management software and other systems within the operation. However, Wi-Fi is not necessarily what allows the robot to physically navigate around the warehouse.
Autonomous mobile robots can use onboard sensors and navigation technology to understand their surroundings, while network connectivity performs a different role behind the scenes.
Understanding that distinction can make it much easier to determine what infrastructure may be required before introducing warehouse robotics.
What Does Wi-Fi Actually Do for Warehouse Robots?
In many warehouse robotics applications, wireless connectivity allows robots to communicate with the wider system.
Depending on the solution, this could include communication with:
- Fleet management software
- Warehouse management systems
- Other warehouse robots
- Workstations
- Automated equipment
- Task management systems
- Monitoring and reporting platforms
For example, a warehouse management or fleet management system may tell a robot that a product needs to be collected from one area and delivered to another.
The robot receives the task and carries it out.
Connectivity therefore plays an important role in coordinating the overall operation, particularly where multiple robots or integrated warehouse systems are involved.
Does Wi-Fi Tell a Warehouse Robot Where to Go?
Not necessarily.
This is one of the most common misconceptions surrounding autonomous mobile robots.
Modern AMRs can use onboard navigation technologies to understand their environment and move around it.
Depending on the robot, these may include:
- LiDAR
- Cameras
- Sensors
- Mapping technology
- Obstacle detection systems
- Simultaneous localisation and mapping, or SLAM
These technologies allow the robot to understand its position and detect what is happening around it.
Rather than following a route purely because a Wi-Fi signal tells it where to turn, the robot can use its onboard systems to navigate through the environment.
The exact navigation technology varies between manufacturers and applications, but it is useful to separate navigation from communication when considering warehouse robotics.
What Is SLAM?
SLAM stands for Simultaneous Localisation and Mapping.
It is a navigation method used by many autonomous mobile robots to build or reference a map of their environment while determining their own position within it.
This allows an AMR to navigate more flexibly than older automated technologies that may rely on fixed infrastructure such as tracks, wires or magnetic tape.
For warehouse applications, this flexibility can be particularly useful.
If a person, pallet or piece of equipment temporarily blocks the robot’s normal route, an AMR may be able to detect the obstruction and respond appropriately rather than simply continuing along a fixed path.
The precise behaviour will depend on the robot and system configuration, but the important point is that navigation can take place using technology onboard the robot rather than relying solely on the warehouse Wi-Fi network.
So, Do You Still Need Good Wi-Fi Coverage?
For many warehouse robotics installations, reliable network coverage is still important.
Even where a robot can navigate independently, it may need connectivity to receive new tasks, report its status or communicate with other systems.
Poor wireless coverage could potentially affect:
- Task allocation
- Fleet coordination
- System monitoring
- Software communication
- Operational data
- Integration with warehouse systems
This becomes particularly important in larger robotic fleets.
If several robots are working together, the fleet management system needs to coordinate which robot performs each task and understand what is happening throughout the operation.
For this reason, network infrastructure should be considered during the planning stage of a robotics project rather than after the robots arrive.
What Happens If the Wi-Fi Goes Down?
This depends on the robot and how the system has been configured.
A loss of network connectivity does not necessarily mean that a robot immediately becomes unable to understand its surroundings.
Because navigation and obstacle detection can be handled by onboard systems, the robot may still be capable of determining its position and responding safely to its environment.
However, losing communication with the wider warehouse system can affect its ability to receive new instructions or coordinate tasks.
The exact response to a network interruption varies between systems, so this is an important question to discuss with a robotics supplier during the specification process.
Businesses should understand what happens if connectivity is temporarily lost and how normal operation is restored.
Does Every Part of the Warehouse Need Wi-Fi?
Coverage requirements depend on where the robots are expected to operate and how the system communicates.
A robot travelling between goods-in, storage, production and dispatch may need reliable connectivity across a much larger area than one working within a relatively small operational zone.
Warehouses can also create unusual challenges for wireless networks.
For example:
- High racking
- Dense stored products
- Machinery
- Walls and partitions
- Large metal structures
- Different floors or operational zones
can all influence network coverage.
An existing Wi-Fi network that works perfectly well for laptops in an office does not automatically mean it is suitable for mobile automation across a warehouse.
Coverage should therefore be assessed based on the actual robot routes and operational requirements.
Do Warehouse Robots Need Special Internet Access?
Wi-Fi and internet access are not the same thing.
A warehouse can have a local wireless network without every device relying continuously on a public internet connection.
Whether external internet access is required will depend on the robotic system.
For example, connectivity may be used for:
- Remote technical support
- Software updates
- Cloud-based monitoring
- Data reporting
- System management
Other functions may take place locally within the warehouse network.
The infrastructure requirements should therefore be established as part of the project rather than assuming that every warehouse robot needs a constant internet connection simply because it uses Wi-Fi.
What About Cybersecurity?
Once warehouse equipment is connected to a wider network, cybersecurity becomes another consideration.
This is not unique to robotics. Modern conveyor controls, warehouse management systems, sensors and other automated equipment may also communicate across operational networks.
Businesses introducing warehouse robots should understand:
- What systems the robots connect to
- What information is transmitted
- How access is controlled
- How software is updated
- Whether remote access is available
- How the system fits within existing IT policies
This may require cooperation between warehouse operations, the robotics supplier and the business’s IT team.
Considering these requirements early can make implementation much smoother.
Should Your Wi-Fi Be Checked Before Installing Warehouse Robots?
It can be worthwhile, particularly for larger or more complex applications.
The robotics supplier will first need to understand how the robots will be used.
This may include:
- Where robots will travel
- Collection and delivery points
- Number of robots
- Existing network coverage
- Integration requirements
- Warehouse management software
- Charging locations
- Areas where signal strength may be limited
From there, any network requirements can be identified before deployment.
This does not necessarily mean an entire warehouse network needs replacing.
In some applications, the existing infrastructure may already be suitable. In others, additional coverage or changes may be recommended.
The important thing is to establish this during the planning stage.
What Other Infrastructure Do Warehouse Robots Need?
Network connectivity is only one part of preparing a warehouse for robotics.
Depending on the application, other considerations can include:
- Suitable travel routes
- Charging points
- Collection and delivery locations
- Floor condition
- Doorways and access points
- Interaction with people and vehicles
- Integration with conveyors or other equipment
- Software integration
One of the advantages of modern autonomous mobile robots is that they can often be introduced without the extensive fixed infrastructure associated with some traditional forms of automation.
However, that does not mean there is no planning involved.
Understanding the wider operating environment is essential to ensuring the robots can perform their intended tasks effectively.
Conclusion
Warehouse robots may use Wi-Fi, but Wi-Fi and robot navigation are not the same thing.
Modern autonomous mobile robots can use onboard sensors, mapping and navigation technology to understand their environment, while wireless connectivity is commonly used to communicate with fleet management software and other warehouse systems.
For many applications, reliable network coverage remains important, particularly where multiple robots need to receive tasks and work together as part of a wider automated operation.
The exact connectivity requirements will depend on the robots, software and application, which is why network infrastructure should be considered during the planning stage of a warehouse robotics project.
