FANUC America Debuts Ultra Lightweight CRX-3iA Collaborative Robot and New Capabilities Across the CRX Lineup

FANUC America, the leading supplier of CNCs, robotics and automation, has expanded its popular CRX collaborative robot series with the introduction of the CRX-3iA , an ultra lightweight cobot designed for fast redeployment across small, high mix tasks. Weighing only 11 kg (24 lbs.), the CRX-3iA can be carried and set up in minutes, giving manufacturers a portable way to automate jobs such as welding, part handling, small assembly, screwdriving, tool positioning and inspection—especially in tight spaces or temporary work areas where permanent fixtures aren’t feasible.

In addition to introducing the newest model in the CRX family, FANUC is rolling out several new capabilities across the full CRX lineup. These enhancements expand the range of applications that collaborative robots can support—from heavier palletizing and high throughput fastening to coordinated welding and advanced motion control—giving manufacturers more flexibility to automate both small, high mix tasks and larger, mass production scale operations.

“The CRX-3iA puts collaborative automation in the hands of operators—literally,” explains Eric Potter, general manager, robot application engineering segment, FANUC America. “Its lightweight design makes it easy to redeploy in minutes, helping manufacturers automate jobs that were once too small, too scattered or too costly to justify. Combined with new capabilities across the CRX lineup, we’re giving our customers more ways to apply collaborative robots safely and productively across their entire operation.”

CRX-3iA: Ultra Portable Automation for High Mix Work

The CRX-3iA brings a new level of mobility and flexibility to FANUC’s collaborative robot family. With a 3 kg payload, 692 mm reach and lightweight design, the CRX-3iA is engineered for rapid repositioning and tight space operation.

CRX-3iA Key Features

• Ultra lightweight design: Can be carried by a single person and quickly moved to workstations, temporary setups or field environments.
• Flexible installation: Supports magnetic bases and offers effortless wall or ceiling mounting with automatic angle detection and no manual input.
• High mix task support: Ideal for welding, part handling, small assembly, screwdriving, tool positioning and inspection tasks.
• Portable welding capability: Can be manually moved to the welding area for fast repositioning with support for touch sensing, eliminating the need for precise robot placement. Additionally, auto weld point detection and auto path generation easily accelerate welding setup.

These capabilities make the CRX-3iA a practical solution for manufacturers seeking to automate small or variable tasks without committing to permanent fixtures or complex integration.

New Capabilities Across the CRX Collaborative Robot Lineup

Several new features and options that expand the performance and versatility of the entire CRX family include:

• New “Triangle Weave” Vertical Up Welding Profile
  A breakthrough solution for out of position welding, FANUC’s newly developed triangle weave profile counteracts weld puddle sag and replicates the precision of a skilled welder, enabling successful Vertical Up welding where automation traditionally struggled. What was once a major challenge can now be achieved with confidence through an intuitive, easy to use interface.
• Enhanced Palletizing Performance
  Palletizing by the CRX-30iA now supports up to 40 kg payloads. When paired with a new high flow air kit designed for large suction grippers, this enhancement enables collaborative palletizing of heavier cases while maintaining safety and ease of use.
• High Inertia Mode for Assisted Heavy Moves
  A new high inertia mode allows CRX cobots to guide extremely heavy loads while a lift assist device carries the weight. This hybrid approach automates previously manual, ergonomically challenging operations while preserving collaborative safety.
• Dual Nut Runner Support
  CRX cobots can now operate dual nut runners to double fastener throughput. An optional internal wiring harness supports clean cable routing and maintains collaborative safety standards.
• CRX on R-50iA Controller
  The CRX lineup will also be available on FANUC’s new R-50iA controller, enabling advanced capabilities including:
  • Python scripting
  • Higher frequency ROS 2 and streaming motion support for AI-driven application
  • Advanced Cybersecurity protection
• Positioner support 
  Support for Auxiliary Axis part positioners now enable coordinated welding and laser applications.

These enhancements broaden the CRX family’s reach into more demanding applications while preserving the simplicity and safety that define collaborative robotics.

FANUC’s CRX-3iA is now available for customer order.
