FAIRINO FR3-C Overview

The FAIRINO FR3-C is the compact member of the FR3 family of 6-axis collaborative robots. It keeps the 3 kg payload and 622 mm reach of the FR3 in a lighter arm of about 10 kg on a 125 mm base, with ±0.05 mm repeatability and a typical TCP speed of 1 m/s. Its sixth joint rotates ±175° rather than ±360°. It fits small cells, mobile carts and stations where arm weight and footprint matter more than top precision. Programming runs through a browser-based web interface, with SDKs for Python, C#, C++ and ROS/ROS2 for custom integration. Communication covers digital and analog I/O, TCP/IP, Modbus TCP/RTU, PROFINET, EtherNet/IP and CC-Link. Protection is IP54 as standard with IP65 optional, and operating noise stays below 65 dB.

FAIRINO FR3-C Review Summary

The FR3-C is the compact, lowest-priced member of FAIRINO's FR3 family. It keeps the 3 kg payload and 622 mm reach of the FR3 in an arm of about 10 kg on a 125 mm base, with ±0.05 mm repeatability. It fits small cells, mobile carts and stations where arm weight, footprint and budget matter more than top precision. It is listed from USD 5,400.

Pros

• Lowest price in the FR3 family

• Arm weight of about 10 kg on a 125 mm base

• 622 mm reach, longer than the 500 mm of the UR3e

• 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

• Sixth joint is limited to ±175° of rotation

• IP54 as standard; IP65 is an option rather than the IP66 of the standard FR3

Who It Is For

The FR3-C fits schools, labs, start-ups and manufacturers that want a capable 3 kg arm at the lowest cost. For tighter tolerances choose the FR3 or FR3-WMS; for more reach, the FR3-WML.
