FAIRINO FR3 Review: Specs, Price and Applications of the 3 kg Cobot
Updated: 7 days ago
The FAIRINO FR3 is a 6-axis collaborative robot with a 3 kg payload, a 622 mm reach and ±0.02 mm repeatability, sold in the United States from USD 6,799. 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 is the smallest standard model in FAIRINO's FR series. It pairs a 3 kg payload and a 622 mm reach with ±0.02 mm repeatability in a 15 kg arm, which makes it a benchtop cobot for precision pick-and-place, light assembly, inspection and lab automation. At USD 6,799 it is also the lowest-priced standard arm in the range.

Design and Build Quality
FAIRINO develops and produces the core components of the FR3 in-house, with a modular joint design. Each joint has full closed-loop torque feedback, which underpins collision detection and smooth hand-guiding.
Protection and Operating Environment
The arm is rated IP66, so it is sealed against dust and strong water jets, an unusual level of protection for a 3 kg benchtop cobot. It operates from 0 to 45 °C at up to 90% non-condensing humidity, and noise stays below 65 dB.
Footprint and Weight
With a 128 mm base and an arm weight of about 15 kg, the FR3 fits on a workbench, a small cart or inside a machine enclosure. The arm is built from aluminium and steel.
Programming and Software
No-Code Teaching
The FR3 is programmed through a graphical interface on a 10.1-inch teach pendant or a web app that runs on a tablet or phone. 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 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 Applications and Use Cases
Pick and Place
Fairino USA offers a turnkey pick-and-place cell built on the FR3 with a pedestal, a configured gripper and a code-free HMI for teaching points and switching recipes. It is listed at USD 12,500 including setup and training, and targets material handling, packaging, kitting and line feeding of small parts.
Bin Picking with Vision
Adding a smart camera turns the same cell into a bin-picking station that also handles presence checks, barcode and QR reading and basic measurement. The FR3 bin-picking package with the vision system is listed at USD 22,900 delivered.
Light Assembly, Inspection and Lab Automation
The ±0.02 mm repeatability suits screwdriving and insertion of small components, positioning cameras or probes for quality checks, and sample handling in laboratories. Its 622 mm reach covers a single workstation; for a wider envelope with the same payload, the long-reach FR3-WML reaches 922 mm.
FAIRINO FR3 Price and Value
The FAIRINO FR3 is listed at USD 6,799 by Fairino USA. Grippers, mounting hardware, vision and integration are quoted separately. Prices are indicative, are not final and may change.
FAIRINO FR3 vs Universal Robots UR3e
The closest equivalent from Universal Robots is the UR3e.
FAIRINO FR3 | Universal Robots UR3e | |
Payload | 3 kg | 3 kg |
Reach | 622 mm | 500 mm |
Repeatability | ±0.02 mm | ±0.03 mm |
IP rating | IP66 | IP54 |
Arm weight | 15 kg | 11.2 kg |
Starting price | From USD 6,799 | From USD 33,800 |
Pros and Cons
Pros
Lowest price among the standard FR series arms
±0.02 mm repeatability for precision work
IP66 protection as standard
622 mm reach, longer than the 500 mm of the UR3e
Open platform: Python, C#, C++ SDKs and ROS / ROS2
Cons
3 kg payload includes the gripper, so usable part weight is lower
At about 15 kg the arm is heavier than the lightweight FR3-WMS and FR3-C variants
End effectors, pedestal and vision are purchased separately
Who Should Buy the FAIRINO FR3?
The FR3 fits electronics and small-parts manufacturers, laboratories, universities and any team that needs an accurate benchtop arm at a low entry price. If the arm will ride on a mobile platform, the lighter FR3-WMS is the better match; if you need more payload, step up to the FR5.
