Choisir un PC de commande pour robots mobiles autonomes AMR et AGV

What an AMR/AGV control PC actually has to do

An autonomous mobile robot's onboard computer is not a desk PC. It runs SLAM and perception (LiDAR + cameras + IMU fusion), executes the motion planner against a deterministic loop, talks to motor drivers over EtherCAT / CANopen / CAN bus, exchanges fleet messages over Wi-Fi or 5G, and sometimes runs vision-based inspection or pick verification on the same box. It has to do all of that on a battery rail, in a vibrating chassis, with a sealed thermal design, for years.

The non-negotiables

• Wide voltage input, typically 9 à 36 VDC to ride out battery discharge, regenerative braking and bus dips
• Vibration- and shock-tolerant build, onboard CPU (not socketed), no spinning disk, soldered RAM where possible
• Fanless cooling, sealed against dust, no fan to fail in a warehouse environment
• Wide operating temperature, at least -20°C to +60°C; -40°C to +80°C for cold-store
• Deterministic I/O, CAN bus, RS-485, isolated GPIO, EtherCAT-capable Ethernet
• Multiple Ethernet, segregated networks for control, vision and fleet
• Wireless, Wi-Fi 6 plus 5G or LTE; dust-protected antenna mounts
• Edge AI compute if perception runs onboard, discrete NPU/GPU or Jetson-class module
• TPM 2.0 for fleet identity and secure update
• Long-term availability, 5 à 7 year lifecycle so production fleets aren't redesigned mid-life

How to map robot class to PC tier

Light-duty indoor AMR / hospital tug

An ARM SBC or low-power x86 is enough, ROS 2 navigation stack, modest perception, battery-rail wide-voltage input. The ECM-ASL3 3.5" SBC (Intel Alder Lake-N / Amston Lake, -40°C to +80°C, 9 à 36 VDC, TPM 2.0, triple M.2, triple Ethernet, three displays) is squarely sized for this, see our ECM-ASL3 coverage. ARM alternatives include the ARM-based SBC range.

Mid-duty AMR with onboard vision

A 3.5" or Thin Mini-ITX SBC with edge AI compute and PCIe expansion for an AI accelerator. The ECM-PTL (Intel Core Ultra Series 3 with integrated NPU, DDR5-7200, PCIe Gen5) covers AI inference on-board without a discrete GPU, see our ECM-PTL coverage.

Heavy AGV / autonomous forklift with multi-camera vision

A fanless box PC with a discrete GPU (Jetson-class or RTX Ada). See how to size the GPU for the math. Avalue's EPC-TWL Twin Lake fanless box covers the wide-voltage, fanless side of this class.

Selection checklist

1. Voltage rail (9 à 24, 9 à 36, 12 à 24?), match the robot's battery and bus
2. Operating temperature including cold-store edge cases
3. Vibration / shock specification, list the actual standards (IEC 60068-2-6/-2-27)
4. Deterministic I/O, count CAN, RS-485, isolated GPIO needs
5. Number of Ethernet segments and which are EtherCAT-capable
6. Wireless plan, Wi-Fi 6 + 5G/LTE on board or via M.2 add-in
7. Perception compute, NPU on-SoC enough, or discrete GPU needed?
8. Mechanical envelope, what physically fits in the chassis
9. Lifecycle, 5+ years for fleet maintainability
