FAIRINO FR3 Overview

The FAIRINO FR3 is the smallest standard model in the FR series of 6-axis collaborative robots. It carries a 3 kg payload over a 622 mm reach with ±0.02 mm repeatability and a typical TCP speed of 1 m/s, and the arm weighs about 15 kg. That combination suits precision pick-and-place, light assembly, inspection and lab automation on a benchtop. Programming runs through a browser-based web interface or teach pendant, with SDKs for Python, C#, C++ and ROS/ROS2 and communication over digital and analog I/O, TCP/IP, Modbus TCP/RTU, PROFINET, EtherNet/IP and CC-Link. Protection is rated IP66, and operating noise stays below 65 dB.

FAIRINO FR3 Review Summary

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.

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 It Is For

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.
