Manufacturers increasingly need automation equipment that can be installed quickly, moved between workstations and adapted to different production tasks.
FANUC introduced the CRX-3iA in April 2026 as an ultra-lightweight collaborative robot. Weighing only 11 kg, it is designed for small workspaces and applications where portability is an important requirement.
Unlike larger collaborative robots designed for heavier handling tasks, the CRX-3iA focuses on lightweight automation, flexible installation and quick redeployment.
| Parameter | Specification |
|---|---|
| Robot Model | CRX-3iA |
| Robot Type | Collaborative Robot |
| Number of Axes | 6 |
| Maximum Payload | 3 kg |
| Maximum Reach | 692 mm |
| Repeatability | ±0.02 mm |
| Mechanical Weight | 11 kg |
| Controller | R-30iB Plus |
| Mounting Options | Floor, Ceiling, Wall, Angle |
Its 11 kg mechanical weight makes the robot easier to transport and reposition than many conventional industrial robots.
The 3 kg payload is intended for lightweight tools and workpieces, including welding torches, sensors and small assembly equipment.
Ultra-lightweight construction
At approximately 11 kg, the CRX-3iA can be carried and repositioned by an operator. This makes it useful for temporary workstations and production environments where automation requirements change frequently.
Flexible mounting options
The robot supports floor, ceiling, wall and angled mounting configurations. It can also be installed using a compatible magnetic base, reducing the need for permanent mechanical fixtures in suitable applications.
Quick redeployment
FANUC highlights features that help operators relocate the robot and resume work with less setup effort. For certain welding applications, the system can use the torch wire to touch a reference surface and recognize its position without repeating the entire teaching process.
Compact working envelope
With a 692 mm reach, the CRX-3iA is designed for smaller workspaces where a larger robot may be difficult to install.
The robot is suitable for lightweight tasks that benefit from portability and flexible installation.
Welding
The CRX-3iA can support lightweight welding equipment and welding sensors. Its compact design is particularly useful for smaller welding jobs and confined work areas.
Small-part handling
It can transfer lightweight components between workstations, support basic pick-and-place tasks and handle small production parts.
Assembly and screwdriving
The robot can be configured with suitable end-of-arm tools for repetitive assembly and fastening operations.
Inspection and tool positioning
With appropriate sensors and fixtures, it can assist with positioning, inspection and other light-duty manufacturing tasks.
The CRX-3iA should not be compared with larger cobots based on payload alone.
| Selection Factor | CRX-3iA Advantage | Larger Cobot Advantage |
|---|---|---|
| Robot Weight | Easier to relocate | More stable installation |
| Payload | Suitable for light tools | Handles heavier workpieces |
| Reach | Compact workspaces | Larger working area |
| Installation | Flexible mounting | More demanding installation |
| Typical Tasks | Light assembly, welding, inspection | Machine tending, handling, palletizing |
If an application requires a payload above 3 kg or a reach beyond 692 mm, a larger collaborative robot may be more appropriate.
Before selecting the CRX-3iA, buyers and automation engineers should review several practical details:
Tool and workpiece weight: The combined load must remain within the robot's rated payload.
Working envelope: Confirm that the 692 mm reach covers the complete operation.
Mounting conditions: Check the installation surface and whether a magnetic mounting solution is suitable.
Controller and accessories: Confirm the required controller configuration, cables, end effectors and application equipment.
Collaborative safety: Conduct a risk assessment for the complete workcell. Collaborative robot classification does not automatically make every application safe for unrestricted human interaction.
The FANUC CRX-3iA is designed for manufacturers who need a lightweight and portable collaborative robot rather than a high-payload handling system.
Its 11 kg body weight, 3 kg payload and 692 mm reach make it suitable for compact workstations, light assembly, welding and small-part handling.
For manufacturers with changing production layouts or limited installation space, the CRX-3iA offers an alternative to permanently installed industrial robots.
