Precision Robotics

A FANUC M-20iB/35S robot in a shipping container. Deploy anywhere. Drill, cut, deburr, and inspect precision parts on site — from mine to shipyard.

FANUC M-20iB/35S IP67 Sealed 35kg Payload ±0.02mm

The Concept

Take the factory to the work. Not the work to the factory.

A standard 20ft shipping container fitted with a 6-axis industrial robot, high-speed spindle, vision system, and dust extraction. It arrives on a flatbed, connects to power, and starts producing precision parts within hours.

No permanent building. No planning permission. No 12-month lead time. When the job is done, the container moves to the next site. Manufacture locally — eliminate import lead times, reduce logistics costs, respond to demand where it happens.

Why This Robot

  • Compact — 205kg, slim inline wrist fits inside a container with room to work
  • Sealed — IP67 handles chips, coolant mist, dust, washdown
  • Strong — 35kg carries spindle + tool changer + workpiece
  • Precise — ±0.02mm holds tolerance across temperature swings
  • Flexible mounting — floor, ceiling, or angled pedestal

Controller: R-30iB Plus

  • iRVision — built-in 2D/3D vision for part location
  • Force sensing — adaptive deburring and polishing
  • DCS Safety — safety-rated speed/position monitoring (reduces fencing)
  • FIELD IoT — remote monitoring and program upload
  • ZDT — predictive maintenance (motor current, vibration, temp)

Deployment Scenarios

Mining

Remote Site Manufacturing

Manufacture replacement brackets, mounting plates, and structural components on-demand at the mine. Eliminates 6-week lead times from distant fabrication shops.

Construction

Modular Building Panels

Pre-drill connection holes in steel framing on the construction site. Ensures precise alignment between modules. Programs loaded per building design.

Energy

Wind/Solar Farm Fitments

Thousands of unique brackets and mounting hardware for renewable installations. Container arrives with the turbines, manufactures fitments as installation progresses.

Marine

Shipyard Plate Work

Container positioned dockside for drilling hull plates, bulkhead brackets, and pipe flanges. IP67 handles the saltwater environment.

Agriculture

Seasonal Equipment Repair

Mobile factory visits farming districts during harvest to manufacture and repair equipment components — combines, planters, irrigation systems.

Defence
