FAIRINO FR3-WML Review: Specs, Price and Applications of the 3 kg Cobot
Updated: 7 days ago
The FAIRINO FR3-WML is a 6-axis collaborative robot with a 3 kg payload, a 922 mm reach and ±0.05 mm repeatability, sold in the United States from USD 7,499. This review covers its full specifications, build quality, programming options, real applications and price, so you can decide whether it fits your automation project.
Quick Verdict
The FR3-WML is the lightweight, long-reach variant in FAIRINO's FR3 family. It carries 3 kg over a 922 mm reach in an arm of only about 11.25 kg, which makes it a natural fit for mobile platforms, compact workstations and light handling where low arm weight is the priority. It is listed at USD 7,499.

Design and Build Quality
The FR3-WML combines the 3 kg payload of the FR3 with the 922 mm reach of the FR5, in an arm that weighs roughly half as much as the FR5. It mounts in any orientation.
Protection and Operating Environment
The arm is rated IP54 as standard, with IP65 available as an option. It operates from 0 to 45 °C at up to 90% non-condensing humidity, and noise stays below 65 dB.
Footprint, Weight and Power
The arm weighs about 11.25 kg on a 128 mm base and is built from aluminium and steel. Rated power is 140 W with a 240 W maximum, a low draw that suits battery-powered mobile bases.
Programming and Software
No-Code Teaching
The FR3-WML is programmed through a graphical interface on a teach pendant or a browser-based web app. Drag teaching lets an operator guide the arm by hand to record positions, so routine handling tasks can be set up without writing code.
SDKs and ROS Support
FAIRINO provides SDKs for Python, C#, and C++, and the FR3-WML supports ROS and ROS2. That makes it usable as a development platform for integrators, universities and research labs.
Industrial Communication
The controller communicates over digital and analog I/O, TCP/IP, Modbus TCP/RTU, PROFINET, EtherNet/IP and CC-Link, covering the common PLC and machine interfaces on a factory floor.
FAIRINO FR3-WML Applications and Use Cases
Mobile Manipulation
Low arm weight and low power draw let the FR3-WML ride on an autonomous mobile robot or a cart without overloading it, while the 922 mm reach gives access to shelves, machines and benches from the platform.
Pick and Place at Compact Workstations
The arm handles light parts across a wider area than the standard FR3, which helps with tray loading, kitting and feeding small machines.
Inspection and Lab Automation
The FR3-WML can move a camera, sensor or sample carrier around a bench or instrument. With ±0.05 mm repeatability it suits handling and inspection rather than the tightest assembly tolerances.
FAIRINO FR3-WML Price and Value
The FAIRINO FR3-WML is listed at USD 7,499 by Fairino USA. Grippers, mounting hardware, vision and integration are quoted separately. Prices are indicative, are not final and may change.

Pros and Cons
Pros
922 mm reach in an arm of about 11.25 kg
Low power draw: 140 W rated
Mounts in any orientation
Arm weight comparable to the UR3e with 422 mm more reach
Open platform: Python, C#, C++ SDKs and ROS / ROS2
Cons
Repeatability of ±0.05 mm is wider than the ±0.02 mm of the standard FR3
IP54 as standard; IP65 is an option rather than the IP66 of the standard FR3
3 kg payload includes the gripper
Who Should Buy the FAIRINO FR3-WML?
The FR3-WML fits mobile robot builders, labs and compact stations that need reach without weight. If you need tighter repeatability and can accept a shorter reach, the FR3-WMS or the standard FR3 is the better choice.
