Overview
The CR-4iA brings FANUC's collaborative safety philosophy to the compact SCARA space, delivering 4 kg payload with precision repeatability. Its 400 mm reach makes it ideal for small component assembly and intricate part positioning in tight work cells.
Technical Specifications
Reach (horizontal) 400 mm, payload 4 kg, repeatability ±0.02 mm, cycle time 0.8–1.2 seconds for small assemblies. Vertical range 500 mm, arm mass 35 kg. ISO/TS 15066 force-limiting certified.
Applications
Small electronics assembly, circuit board component placement, precision screw insertion, small parts kitting, and medical device sub-assembly. Popular in high-mix manufacturing and contract assembly shops.
Integration & Programming
Simplified teach pendant programming, vision-guided pick-and-place, and iRVision compatibility. Force feedback and collaborative safety are intrinsic.
Market Position
For manufacturers of small, precision products requiring flexible collaborative assembly without dedicated infrastructure, the CR-4iA is the platform of choice.
FAQ
What is the vertical range and how does it compare to traditional SCARA robots?
The CR-4iA has a 500 mm vertical range, matching traditional SCARA footprints. Force limiting adds 15–20% to cycle time vs. non-collaborative SCARA arms.
Can I use the CR-4iA for vision-guided assembly?
Yes, FANUC iRVision is integrated, enabling dynamic part location and component verification in real time during assembly.
What is the learning curve for programming the CR-4iA?
Very low; most operators achieve first production program within 30 minutes with basic manufacturing knowledge. Drag-and-drop task programming is available.
Is the CR-4iA suitable for continuous 24/7 operation?
Yes, it's rated for continuous duty with preventive maintenance every 12,000 hours. Force-sensing calibration is recommended every 6,000 hours.
How does cost compare to non-collaborative SCARA robots?
Typically 30–50% more expensive due to force-limiting systems and safety certification, but eliminates need for safety guarding and reduces setup time.
