The FAIRINO FR3 is a 6-axis collaborative robot designed for industry automation in electronics, machining, and general manufacturing. It offers a 3 kg payload, 622 mm reach, and ±0.02 mm repeatability for precise work in compact spaces. Programming is accessible via a browser-based WebAPP and optional Teach Pendant, with SDKs for C# / C++ / Python and ROS / ROS 2 for integration. Weighing around 15 kg, it has an IP54 rating (IP65 optional) and mounts in any orientation. Preconfigured factory kits — vision, palletizing, welding, bin-picking, and CNC tending — speed setup and ease integration.
The FAIRINO FR3 has a 3 kg rated payload but can handle up to 5 kg with a close center of gravity and limited motion range.
The FR3 has a 622mm TCP reach within a spherical-segment workspace, enabling overhead and below-base positioning. Joint limits define this envelope: base ±175°, shoulder +85°/−265°, elbow ±150°, and wrist axes +85°/−265°, ±175°, and ±175°, leaving only a small unswept area at the base.
The FR3 achieves ±0.02 mm repeatability (ISO 9283), with 1 m/s TCP speed and joint velocities up to ±180°/s, enabling fast, precise motion.

The controller supports point-to-point and linear moves with joint-overspeed protection to maintain path accuracy near joint limits. B-spline look-ahead planning smooths motion and reduces jerk, while a singularity strategy ensures continuous travel through difficult poses.
The FR3 includes an emergency stop on the teach pendant or button box that instantly halts motion and cuts joint power.
An end-of-arm LED shows robot states — Automatic, Manual, Drag, Start/Stop, Enable, and errors — to keep operators informed during close interaction.
The FR3 supports hand-guiding via Drag mode with user-defined joint soft limits to restrict movement. Collision detection is adjustable by level (1–10 or custom %) with selectable responses — error-stop or continue — allowing behavior to match risk assessments.
The FR series meets ISO 10218, ISO 13849, ISO/TS 15066, CE, and RoHS 2.0 standards, enabling compliant human-robot collaboration technology deployment.
The FR3 uses FAIRINO’s self-developed browser-based WebAPP for programming on PC, tablet, or phone, with a mirrored interface on the optional teach pendant.
The interface supports graphical programming and Lua scripting, allowing users to drag-and-drop functions or write code in one environment.
FAIRINO offers SDKs for C#, C++, and Python, plus ROS/ROS2 integration for robotics secondary development.
FAIRINO’s application kits offer no-code workflows — palletizing sets up in three guided steps, and welding includes prebuilt logic. For advanced control, the Controller Communication Protocol provides API access to motion, I/O, safety, and peripherals.
The WebAPP and teach pendant UI support multiple languages, including Chinese, English, French, and Japanese, to suit local operators.
The FR3 offers 50+ connectivity options. Its controller includes 16 DI, 16 DO, 2 AI, 2 AO, and 2 high-speed pulse inputs (24 V) for cell-level I/O. The tool flange adds 2 DI, 2 DO, 1 AI, 1 AO, and a 24 V / 1.5 A power rail for end-effector integration.
The digital I/O uses 24 V industrial signaling with selectable NPN/PNP wiring. Outputs sink up to 1 A (≈0.5 V drop, ≤0.1 mA leakage), and inputs trigger at 11–30 V. An internal 24 V supply (1.5–2 A) supports light loads; external power is recommended for higher draw.
Standard networking includes Ethernet (TCP/IP) with Modbus TCP/RTU for PLC/SCADA integration. Optional MiniPCIe cards add EtherCAT, EtherNet/IP, PROFINET, and CC-Link IE Field Basic for fieldbus support.
FAIRINO’s Safety Box connects via RJ45 and PoE, presenting the WebAPP over TCP/IP for easy operator access, commissioning, and handshaking on the plant network.
The FAIRINO FR3 is a 6-axis cobot with aluminum and steel links on a 128 mm footprint, weighing ≈15 kg for stability and low inertia. It’s rated IP54 (IP65 optional), operates at 0–45 °C and up to 90% Relative Humidity (non-condensing), runs below 65 dB, and supports any mounting orientation for flexible cell layouts.
The controller has a galvanized IP54-rated chassis, measuring 245 x 180 x 44.5 mm and weighing 2.1–2.5 kg.
The optional teach pendant is an IP54-rated ABS/PP unit, 268 x 210 x 88 mm, weighing 1.6 kg — durable and compact for industrial use.
Installations should avoid shock, corrosive or explosive environments, and unstable power — standard practice for collaborative arms.
The standard FAIRINO FR3 collaborative robot arm package includes:
The FR3 ships fully assembled with a separate control and button box. After securing the base and connecting the cables and power, it’s ready to run via the WebAPP.

Operational maintenance (during planned stops)
Power down, then visually inspect the robot–controller cable, base and tool bolts, joints, and seals. Clean the arm with water, isopropyl alcohol, or 10% ethanol/naphtha. Never use compressed air on the arm or in the control box. Small grease traces at joints are normal and don’t affect lifespan.
Preventive maintenance (monthly & semi-annually)
Inspect the arm's rear covers, screws, rubber rings, and cables. Check base and tool-flange fasteners with a torque wrench to spec. Test the control system — E-stop, safety I/O, and mode switching. Verify pendant cable condition, clean the control-box air filter, re-seat terminals if needed, and ensure ground resistance is ≤ 1 Ω.
Comprehensive maintenance (annually)
Repeat full arm and controller checks. Test E-stop from the pendant and button box — verify the robot stops, joint power is cut, then recovers. Re-check mounting torque: base 4xM6 ≥ 10 Nm with Ø5 mm pins; tool flange 4xM6 at 8 Nm, bolts ≤ 8 mm long. Avoid storage over 6 months without inspection.
