Enabling factory automation: warehouse robotics & autonomous mobile robots in action

Factory and warehouse automation has evolved rapidly as manufacturers and logistics operators look for new ways to increase productivity, improve safety and create more flexible operations. Autonomous mobile robots (AMRs), automated guided vehicles (AGVs), robotic picking systems and intelligent material-handling equipment are becoming increasingly connected, using advanced sensors, cameras and wireless communications to navigate dynamic industrial environments.

Artificial intelligence and machine vision are further expanding what these systems can accomplish. Modern warehouse robots can collect and process data from multiple cameras, LiDAR, proximity sensors and other sensing technologies to identify objects, optimize routes and respond to changing conditions in real time. As fleets of autonomous systems grow, reliable communication between robots, onboard computing systems and wireless infrastructure becomes increasingly important.

This evolution is placing greater demands on the connectivity architecture inside industrial robotics. High-speed data transmission, low-latency wireless communication, compact packaging and reliable operation in environments exposed to vibration, movement, dust and moisture all need to be considered when designing the RF signal path.

How Are Autonomous Mobile Robots Used in Warehouse Automation?

AMRs are designed to move through warehouses and manufacturing facilities with greater autonomy than traditional fixed automation systems. Instead of relying exclusively on predetermined paths, modern robotic systems can use cameras, LiDAR, sensors, wireless connectivity and onboard computing to understand their surroundings and make navigation decisions.

Common applications include:

• Material transport between workstations
• Automated picking and order fulfillment
• Pallet and container movement
• Inventory scanning and tracking
• Automated shelving and storage systems
• Autonomous tugs and forklifts
• Inspection and monitoring
• Collaborative robotic systems

As these applications become more sophisticated, the amount of data moving through the robot increases. Cameras, sensors, antennas and compute modules require reliable connections that can support both high-speed data transmission and wireless communication.

This makes the RF interconnect system an important part of the overall robotic architecture.

Why Is RF Connectivity Important for Warehouse Robotics?

Warehouse robots depend on multiple communication paths. Wireless connections allow robots to communicate with warehouse management systems, other robots and network infrastructure, while internal RF connections transmit signals between antennas, cameras, sensors and onboard computing equipment. The RF system may support functions such as Wi-Fi and cellular connectivity, positioning, machine vision, collision avoidance, telemetry and sensor data transmission. The challenge is maintaining signal integrity while integrating these capabilities into equipment that is increasingly compact, mobile and data-intensive.

RF connectors and cable assemblies used in warehouse robotics may need to provide:

• High-speed data transmission
• Reliable RF performance
• Compact footprints
• High-density connectivity
• Resistance to vibration and mechanical movement
• Environmental protection
• Flexible cable routing
• Secure mating
• Reliable performance over repeated operating cycles

Amphenol RF offers a broad portfolio of RF connectors and RF cable assemblies that can address these requirements throughout the robotic system.

High-Speed Connectivity for Cameras, Sensors and Compute Modules

Machine vision is becoming increasingly important to automated warehouse operations. Cameras and sensors allow robots to detect objects, recognize inventory, navigate aisles and identify potential obstacles. These systems can generate significant amounts of data that must move quickly between sensing equipment and onboard processors. Amphenol RF AUTOMATE® Mini-FAKRA Type A connectors provide a compact, high-speed interconnect option for camera and sensor architectures.

Rugged RF Connections for Demanding Industrial Environments

Warehouse and factory environments can expose electronic systems to conditions that are very different from those experienced by stationary consumer electronics. Continuous movement can introduce vibration and mechanical stress. Equipment may encounter dust, moisture and temperature fluctuations. Some robotic systems also operate in loading areas, refrigerated facilities or other environments where additional protection is required.

Amphenol RF offers several rugged connector families that can address these requirements:

TNC connectors use a threaded coupling mechanism that helps maintain a secure connection in applications subject to vibration. Standard TNC designs support frequencies through 11 GHz, with extended-range designs available through 18 GHz. IP67 options are also available for applications requiring environmental sealing.

N-Type connectors provide another rugged, threaded RF interface for wireless infrastructure, industrial and outdoor applications. Standard designs operate through 11 GHz, with extended-range options supporting frequencies through 18 GHz.

Amphenol RF also offers IP-rated and ruggedized configurations across multiple connector families for applications where exposure to environmental conditions is a concern.

Miniaturization Is Changing Robotic System Design

Warehouse robots are becoming more capable without necessarily becoming larger. Engineers are integrating additional sensors, radios, processors and antennas into limited spaces, increasing the importance of component miniaturization. This creates a challenge for RF design. Smaller connectors need to occupy less PCB and enclosure space while maintaining the electrical performance required by the application.

Micro-miniature and ultraminiature RF interfaces can help engineers maximize available space for these increasingly complex architectures. Compact RF connections are particularly useful for antenna feeds, embedded wireless modules and internal RF signal paths where traditional connector footprints may be impractical.

For systems requiring extremely compact board-to-board connectivity at higher frequencies, SMP connectors provide broadband performance through 40 GHz in a compact push-on, blind-mate interface.

Supporting Wireless Communication Across the Warehouse

An individual AMR does not operate in isolation. A modern automated warehouse can include fleets of mobile robots communicating with access points, control systems, edge computing infrastructure and other connected equipment. Reliable wireless communication is essential for coordinating these systems. Depending on the application, warehouse robotics may use Wi-Fi, private cellular networks, Bluetooth, GNSS or other wireless technologies. The antennas supporting these networks must be connected to radios through an RF signal path designed to minimize unnecessary signal loss and maintain reliable performance.

Connector selection, cable type, cable length, antenna placement and routing can all influence RF performance. For external antenna and wireless infrastructure connections, Amphenol RF's TNC and N-Type product families provide rugged threaded interfaces designed for secure mating. Multiple configurations and cable assembly options allow these interfaces to be integrated into wireless infrastructure and industrial equipment. As warehouses deploy greater numbers of connected devices, engineers also need to consider the RF environment at the system level. Multiple radios, antennas and wireless protocols operating in close proximity can increase the complexity of maintaining dependable connectivity.

Camera and Vision Systems Require Reliable Interconnects

Machine vision has moved beyond basic obstacle detection. Cameras can support navigation, barcode and label recognition, inventory identification, quality inspection and AI-enabled object recognition. These applications create additional connectivity requirements inside the robot. Camera connections may need to support high data rates while fitting within compact assemblies and maintaining reliable performance under vibration and continuous movement. In modular systems, blind-mate connectivity can also simplify assembly, installation and maintenance.

Amphenol RF SMP connectors combine a compact footprint with push-on blind-mate capability and support frequencies up to 40 GHz, depending on configuration. These characteristics make SMP an option for high-density, high-frequency board-to-board and module-to-module RF connections.

SMP cable assemblies extend the interface to cable-to-board applications and provide additional flexibility for routing RF signals through compact equipment.

For 75-ohm camera and video architectures, HD-AFI connectors provide a high-float blind-mate interface designed to accommodate axial and radial misalignment. The series is available for board-to-board applications and can support machine vision and industrial inspection systems.

These options allow engineers to select an interface based on the electrical architecture, available space and mechanical requirements of the vision system.

What Should Engineers Consider When Selecting RF Interconnects for Warehouse Robots?

There is no single RF connector that addresses every connection within an autonomous robot. Different areas of the system have different electrical, mechanical and environmental requirements. Engineers should consider several factors when selecting an RF interconnect:

Frequency and bandwidth: Determine the frequency range and data requirements of the antenna, camera, sensor or communication system.

Available space: Evaluate PCB footprint, connector mating height and the amount of room available for cable routing.

Environmental exposure: Determine whether the connection requires protection from moisture, dust or other environmental conditions.

Vibration and movement: Select an interface and cable assembly capable of maintaining a secure connection in a mobile system.

Cable flexibility: Tight routing paths and compact assemblies may require flexible or micro-coaxial cable options.

Connection density: Multiport interfaces such as AUTOMATE Mini-FAKRA can help consolidate multiple high-speed connections when several cameras or sensors are integrated into the same system.

Assembly requirements: Blind-mate, push-on and threaded interfaces offer different advantages depending on how the equipment will be manufactured, installed and serviced.

Considering these requirements early in the design process can help engineers build an RF architecture that supports current performance requirements while providing flexibility for future system expansion.
