Fanuc New Era in Flexible Automation with the Lightweight Collaborative Robot CRX-3iA

[Hasan S. Cemkan]

FANUC America has added the CRX-3iA model to its collaborative robot series, weighing only 11 kg. This ultra-light robot is designed for quick repositioning in high-mix, small-scale applications where permanent automation is not suitable.

### CRX-3iA Features and Portability

• Maximum payload capacity: 3 kg
• Reach: 692 mm
• Easily portable by a single operator and set up in minutes
• Magnetic base and wall/ceiling mount support
• No manual calibration needed with automatic mounting angle detection

The CRX-3iA is ideal for delicate tasks such as screwing, tool positioning, inspection, and small assembly in confined spaces.

### Advanced Welding Profile and Automatic Functions

• Automatic weld point detection and automatic path generation are supported
• Touch sensing eliminates the need for precise initial placement
• "Triangle Weave" vertical-up welding profile mimics the skillful techniques of manual welding by preventing weld pool sagging caused by gravity

### Reinforced CRX Series for Heavy Loads and Mass Production

• The CRX-30iA model can handle loads up to 40 kg
• The new high-flow air kit allows the use of large suction grippers
• High inertia mode enables ergonomic and safe handling of heavy loads with lifting assist devices
• Supports simultaneous operation of two nut tightening devices, doubling efficiency in mass production

### R-50iA Control Unit and New Digital Integration

• Python script support simplifies software integrations
• Higher frequency motion streaming is provided for Robot Operating System (ROS 2) and artificial intelligence applications
• Advanced cybersecurity measures are in place
• Coordinated motion is achieved in complex laser and welding processes by supporting control with auxiliary axis positioners

### Strategic Contribution to Flexible Automation
FANUC's CRX series addresses various needs, from 11 kg portable models to 40 kg palletizing systems, bringing flexibility to HMLV (high-mix, low-volume) production. This provides automation solutions that respond quickly to changing market demands without being tied to fixed infrastructure.
