FAIRINO FR3 vs. KUKA LBR iisy 3 R760: Compact 3 kg Cobot Value vs. Premium German Industrial Engineering
The FAIRINO FR3 and KUKA LBR iisy 3 R760 are compact six-axis collaborative robots designed for lightweight industrial automation. Both robots have a nominal payload of 3 kg, support flexible mounting and can automate applications such as electronics assembly, inspection, laboratory handling, machine tending, dispensing, testing and pick-and-place operations.
Despite sharing the same nominal payload class, these cobots represent very different purchasing strategies.
The FAIRINO FR3 is a compact, accuracy-focused cobot with a public U.S. price of $6,799, 622 mm reach, ±0.02 mm repeatability, a 15 kg robot-arm weight and a published maximum payload of 5 kg under applicable operating conditions.
The KUKA LBR iisy 3 R760 is a premium German industrial cobot with 760 mm reach, integrated joint torque sensing, KUKA’s iiQKA.OS2 software environment and the KR C5 micro-2 controller. KUKA does not publish a fixed U.S. MSRP on its official product page, but a European automation marketplace lists the robot at €23,445 excluding VAT, equivalent to approximately $26,700 using the exchange rate available when this comparison was prepared.
The central comparison is therefore:
FAIRINO FR3 = lower acquisition cost, stronger published repeatability, lower arm weight, payload headroom and open development options.
KUKA LBR iisy 3 R760 = longer reach, joint torque sensing, force-control capability and integration with KUKA’s mature industrial automation ecosystem.
Quick Verdict
For manufacturers seeking an affordable compact cobot with strong repeatability, open software-development options and a transparent U.S. purchase price, the FAIRINO FR3 offers the stronger price-to-capability proposition.
For manufacturers already standardized on KUKA equipment—or applications that specifically benefit from integrated joint torque sensing, iiQKA.OS2, KUKA engineering tools and additional reach—the LBR iisy 3 R760 may justify its substantially higher acquisition cost.

Why the KUKA LBR iisy 3 R760 Is the Correct KUKA Comparison
The LBR iisy 3 R760 is the most appropriate KUKA comparison for the FAIRINO FR3 because both robots have a nominal payload of 3 kg and are designed for compact collaborative automation.
Both models provide:
A 3 kg nominal payload
Six controlled axes
Compact industrial construction
Flexible mounting positions
Hand-guided or simplified programming workflows
Support for pick and place, inspection, assembly and machine tending
Collaborative operation when the completed application passes its required risk assessment
This is not a perfect one-to-one comparison. The KUKA has 138 mm more reach and integrated torque sensors in every joint, while the FAIRINO publishes significantly better repeatability, lower arm weight, greater payload headroom and a dramatically lower price.
The two cobots therefore compete in the same payload category but target different commercial priorities.
1. Price and Initial Investment
The FAIRINO FR3 is publicly listed at $6,799 in the United States.
The KUKA LBR iisy 3 R760 is listed by Unchained Robotics at €23,445 excluding VAT. At approximately $1.139 per euro, that is roughly $26,700 before VAT, international shipping and other project costs.
Price Metric | FAIRINO FR3 | KUKA LBR iisy 3 R760 |
Public reference price | $6,799 | Approx. $26,700 |
Price difference | — | $19,901 more |
Price multiple | 1.00× | Approximately 3.93× |
FAIRINO price reduction | — | Approximately 74.5% lower |
The KUKA reference price is almost four times the public FAIRINO USA price. This does not mean that the complete FAIRINO automation cell will always cost 74.5% less. Integration, tooling, safety equipment, engineering, training and commissioning can represent a substantial portion of the complete project.
However, a difference of approximately $19,900 in robot acquisition cost is commercially significant.
That amount could potentially fund:
A collaborative gripper
A machine-vision system
Custom fixtures
A robot pedestal
Safety scanners
Integration engineering
Operator training
Spare parts
Additional tooling
Part-feeding equipment
A second compact automation station
For manufacturers planning several similar cells, the capital difference becomes even more substantial. Four FR3 robot arms at the public price would cost approximately $27,196—roughly comparable to the converted public reference for one KUKA robot before other project costs.
Price Verdict
The FAIRINO FR3 has the decisive acquisition-cost advantage.
The KUKA may justify its premium where joint torque sensing, force control, KUKA plant standardization, iiQKA.OS2 or worldwide KUKA support materially reduces engineering risk. For straightforward handling, dispensing, inspection and machine-tending applications, the FR3 provides a much lower financial entry point.
2. Payload Capacity
Both robots have a nominal payload of 3 kg.
FAIRINO also publishes a maximum FR3 payload of 5 kg. This higher figure should not be interpreted as an unrestricted continuous payload. The allowable load depends on center of gravity, robot pose, speed, acceleration, tool design and duty cycle.
KUKA documents a maximum payload of 3.34 kg when the load’s center of mass is positioned at 0 mm. KUKA instructs users to validate the specific load case using KUKA.Load or KUKA Compose.
Payload includes everything attached to the tool flange:
Gripper
Tool changer
Camera
Force sensor
Cable brackets
Vacuum components
Dispenser
Screwdriver
Adapter plate
Fasteners
Workpiece
A 1.8 kg component combined with a 0.8 kg gripper, 0.2 kg adapter and 0.2 kg sensor already consumes the complete 3 kg nominal payload.
The FR3’s published payload headroom can therefore be meaningful when a compact application requires heavier tooling. It must still be validated for the exact load case.
Payload Verdict
The robots are equal at their nominal 3 kg rating.
The FAIRINO FR3 wins on published maximum payload headroom, while KUKA provides a conservative and clearly qualified maximum of 3.34 kg at a 0 mm center-of-mass position.
3. Reach and Working Envelope
The KUKA LBR iisy 3 R760 has a maximum reach of 760 mm.
The FAIRINO FR3 has a reach of 622 mm.
The KUKA therefore provides:
760 mm − 622 mm = 138 mm of additional reach
That is approximately 22.2% more reach than the FAIRINO FR3.
An additional 138 mm can be valuable when the robot must:
Reach into a CNC machine
Serve two adjacent fixtures
Cover a wider inspection table
Transfer components between stations
Reach around a machine door
Operate over a larger laboratory workspace
Pick components from multiple trays
Use a shorter and more rigid tool extension
Reach must still be evaluated using the complete work envelope rather than a single maximum-radius number. A target point may fall within the nominal reach but remain inaccessible at the required tool orientation.
The FR3’s shorter reach can also be beneficial. A compact work envelope may simplify risk reduction, reduce unnecessary movement and fit more naturally into bench-level applications where the robot operates close to its base.
Reach Verdict
The KUKA LBR iisy 3 R760 has the clear reach advantage.
The FR3 remains the more compact option for automation cells where all required positions fit inside its 622 mm working radius.
4. Repeatability and Precision
FAIRINO publishes FR3 pose repeatability of ±0.02 mm under ISO 9283.
KUKA publishes LBR iisy 3 R760 pose repeatability of ±0.1 mm under ISO 9283.
On the headline specification, the FR3’s repeatability tolerance is five times tighter:
0.1 mm ÷ 0.02 mm = 5
Repeatability measures how consistently a robot returns to a previously taught pose under defined test conditions. It is not the same as absolute positioning accuracy.
Actual process quality also depends on:
Tool-center-point calibration
Base calibration
Fixture rigidity
Part variation
Gripper compliance
Camera calibration
Temperature
Payload
Robot speed
Tool wear
Process forces
External sensors
For repetitive point-to-point operations, the FR3’s published ±0.02 mm figure is a meaningful strength. This can benefit electronics handling, inspection, small-component placement, dispensing and other tasks where consistent positioning matters.
The KUKA’s integrated torque sensors can create a different type of process advantage. In contact-sensitive assembly, insertion or hand-guided applications, force awareness may matter more than the smallest repeatability number.
Repeatability Verdict
The FAIRINO FR3 has the stronger published repeatability specification.
The KUKA becomes more attractive when force sensing, compliance and controlled physical interaction are more important than headline point-to-point repeatability.
5. Speed and Cycle-Time Potential
FAIRINO publishes a typical FR3 TCP speed of 1 m/s, with joint speeds of up to 180°/s.
KUKA promotes the LBR iisy family for high joint speeds and short industrial cycle times, but the current U.S. family page does not provide a simple model-specific TCP-speed number for the 3 R760. The final value should be confirmed using the technical documentation supplied with the exact robot and software configuration.
Cycle time cannot be predicted from a single speed number. It also depends on:
Acceleration and deceleration
Payload
Center of gravity
Distance between points
Tool weight
Robot pose
Safety limits
Human access
Gripper closing time
Vision-processing time
Machine cycle time
Part stability
Communication latency
A robot may support fast joint movement but operate at a much lower safe speed when working close to people.
Speed Verdict
The FR3 provides the clearer public TCP-speed specification.
KUKA emphasizes industrial dynamics, but buyers should obtain the model-specific performance documentation and test the real application before making a cycle-time decision.
6. Robot Weight and Installation
The FAIRINO FR3 weighs approximately 15 kg.
The KUKA LBR iisy 3 R760 weighs approximately 22.8 kg.
The FR3 is therefore approximately 7.8 kg lighter, or about 34% lighter relative to the KUKA arm.
A lower robot weight can simplify:
Manual installation
Workbench mounting
Mobile-cart integration
Educational deployment
Laboratory use
Relocation between machines
Overhead installation
Structural-frame design
Shipping and handling
Robot weight is not the same as total system weight. The controller, pendant, cables, mounting plate, pedestal, safety equipment and tooling must also be considered.
KUKA’s additional weight may reflect its industrial construction and integrated sensing architecture. For a permanent floor-mounted system, the weight difference may have little operational importance.
Installation Verdict
The FAIRINO FR3 has the portability and installation-weight advantage.
Both robots support flexible mounting, but the FR3 is easier to accommodate where the supporting structure or mobile platform has limited capacity.
7. Protection Rating and Environmental Suitability
FAIRINO lists the FR3 as IP54 standard, with IP65 available as an option.
The current KUKA U.S. product page lists the LBR iisy 3 R760 as IP30. Some regional or older KUKA materials have displayed different protection information, so buyers should verify the protection rating on the exact supplied quotation and robot documentation.
The distinction matters:
IP30 provides protection against certain solid objects but does not provide a rated water-ingress level.
IP54 provides limited dust protection and protection against splashing water.
IP65 provides dust-tight protection and protection against water jets under defined test conditions.
None of these ratings automatically makes a complete robot cell suitable for food contact, washdown, explosive environments, outdoor installation or exposure to aggressive chemicals. The controller, teach pendant, connectors, tooling and cables may have different ratings.
Protection Verdict
The FAIRINO FR3 has the stronger published protection configuration, particularly when ordered with optional IP65.
For the KUKA 3 R760, confirm the exact IP rating before specifying the robot for dusty or moisture-prone environments.
8. Force Sensing, Torque Feedback and Collaborative Operation
KUKA states that the LBR iisy platform includes joint torque sensors in every axis. These sensors support:
Detection of external forces
Hand-guided teaching
Collision monitoring
Force-controlled applications
Compliant assembly
Joining operations
Human-robot collaboration
Process optimization
This is one of the strongest technical reasons to select the KUKA.
The FAIRINO FR3 uses closed-loop joint torque feedback and supports hand-guided teaching, collision-related safety functions and collaborative workflows. However, buyers should not assume that the FR3’s torque-feedback architecture is identical to KUKA’s published integrated joint-torque-sensor system.
For simple pick and place, inspection or dispensing, external force control may not be necessary. For insertion, surface contact, delicate assembly or physical operator guidance, KUKA’s sensing architecture may create a meaningful advantage.
A collaborative robot is not automatically safe in every application. The complete system must be evaluated, including:
Tool shape
Workpiece edges
Pinch and crushing hazards
Robot speed
Payload
Stopping distance
Human access
Nearby machines
Process hazards
Safety-rated monitoring
Emergency-stop design
Force-Control Verdict
The KUKA LBR iisy 3 R760 has the stronger published force-sensing and compliant-control proposition.
The FR3 remains suitable for many collaborative applications where conventional positioning, safe motion control and external tooling meet the process requirements.
9. Controller and Programming Experience
FAIRINO FR3
The FR3 can be programmed through a 10.1-inch teach pendant or a browser-based WebApp. FAIRINO also provides secondary-development support using technologies including:
C#
C++
Python
ROS
ROS 2
TCP/IP
Modbus TCP/RTU
Industrial-network options depending on controller configuration
The browser interface can be useful when a manufacturer wants to access programming and setup without relying exclusively on a dedicated proprietary pendant.
KUKA LBR iisy 3 R760
The KUKA uses the KR C5 micro-2 controller and iiQKA.OS2. KUKA positions this environment around intuitive operation, built-in templates, programming assistance, diagnostics and scalability across robot applications.
The KUKA environment is especially attractive to:
Existing KUKA factories
KUKA-trained automation engineers
System integrators using KUKA standards
Plants that want unified engineering across cobots and industrial robots
Companies using iiQWorks simulation and virtual commissioning
Applications requiring KUKA service and training infrastructure
Programming Verdict
FAIRINO is stronger for buyers prioritizing open development, browser-based operation and lower-cost customization.
KUKA is stronger for organizations already invested in KUKA’s industrial software, engineering and service ecosystem.
10. I/O, Communication and Peripheral Integration
The FAIRINO FR3 publishes detailed tool-side connectivity:
FR3 Tool Interface | Quantity |
Digital inputs | 2 |
Digital outputs | 2 |
Analog inputs | 1 |
Analog outputs | 1 |
High-speed pulse inputs | 2 |
Tool power | 24 V DC, 1.5 A |
The controller provides 16 digital inputs, 16 digital outputs, two analog inputs and two analog outputs. Standard communication includes I/O, TCP/IP and Modbus TCP/RTU, with additional network options available depending on the supplied controller.
KUKA documents internal routing from axis 1 to axis 6 that includes eight control cables and a 1 Gbit Ethernet cable. Available controller interfaces include 24 V digital I/O, EtherCAT and configuration-dependent KUKA options.
KUKA’s integration advantage is not simply the number of terminals. It is the broader industrial ecosystem around controller options, KUKA software, safety integration, engineering tools, fieldbus communication and certified automation partners.
Integration Verdict
The FR3 provides the clearer standard tool-I/O specification and an open development route.
The KUKA offers strong plant-level integration and internal media routing, particularly for manufacturers using KUKA automation standards.
11. Electronics Assembly
Both robots are relevant to electronics manufacturing.
The FR3’s strongest advantages are:
±0.02 mm published repeatability
Low 15 kg robot weight
Compact 128 mm footprint
3 kg nominal payload
Published 5 kg maximum headroom
Analog and digital tool I/O
Low acquisition price
The KUKA’s strongest advantages are:
760 mm reach
Integrated torque sensing
ESD-oriented industrial positioning
Force-controlled assembly
KUKA electronics-industry experience
iiQKA.OS2 workflow
For conventional component transfer, testing, screwdriving or inspection, the FR3 may deliver the required performance at a much lower price.
For delicate insertion, connector mating or assembly processes that benefit from direct force feedback, the KUKA may provide the stronger technical platform.
12. Machine Tending
Compact cobots are frequently used to load and unload:
CNC machines
Test equipment
Laser markers
Small presses
Measurement stations
Injection-molding equipment
Laboratory instruments
The KUKA’s additional 138 mm of reach can make it easier to reach into a machine or move between the machine and a nearby tray.
The FR3’s lower price and lower weight can make it economical to deploy one robot at each machine rather than moving a more expensive cobot between stations.
For machine tending, buyers should model:
Door clearance
Required wrist orientation
Tool length
Fixture position
Part weight
Gripper weight
Machine interface
Safety zones
Required cycle time
Machine-Tending Verdict
Choose the KUKA when the additional reach or KUKA plant integration is essential.
Choose the FR3 when the application fits within 622 mm and price, repeatability and multi-cell deployment are more important.
13. Inspection and Quality Control
The FR3’s published ±0.02 mm repeatability makes it attractive for repeatable camera positioning, gauge loading, scanning and test-fixture handling.
The KUKA provides more reach and integrated force awareness, which can be useful when the robot must:
Place a probe against a component
Apply controlled contact force
Move between multiple inspection stations
Perform touch-based validation
Handle sensitive components
Work in a KUKA-standardized production environment
The final measurement quality normally depends more on the inspection sensor and calibration method than on robot repeatability alone.
Inspection Verdict
The FR3 offers strong value for position-based inspection.
The KUKA is particularly attractive for force-sensitive inspection and larger inspection workspaces.
14. Laboratory and Research Automation
The FR3 is well suited to budget-sensitive laboratories, educational institutions and research teams that value:
Python development
ROS and ROS 2 support
Compact dimensions
Low arm weight
Browser-based programming
Lower hardware cost
Published tool I/O
High repeatability
The KUKA is attractive for advanced research involving:
Human-robot interaction
Force control
Contact-rich manipulation
Joint-torque data
Industrial HRC workflows
KUKA controller research
Digital commissioning
Industrially representative training
Laboratory Verdict
The FR3 is the stronger budget-conscious research and education platform.
The KUKA is the stronger premium platform when integrated joint torque sensing or KUKA industrial architecture is central to the research.
15. Dispensing and Gluing
The FR3’s repeatability and analog tool connectivity are useful for:
Adhesive dispensing
Sealant application
Precision dosing
Laboratory fluid handling
Conformal coating
Small-component gluing
The KUKA’s longer reach can cover larger parts, while force sensing may help with contact-based processes.
Dispensing quality also depends on:
Material viscosity
Pump stability
Nozzle condition
Trigger timing
Path velocity
Workpiece positioning
Temperature
Robot calibration
Dispensing Verdict
The FR3 is the stronger value choice for compact precision-dispensing cells.
The KUKA may be preferable when the process requires additional reach, force sensing or KUKA-standard plant integration.
Application-Fit Comparison
Application | Stronger FR3 Advantages | Stronger KUKA Advantages |
Electronics handling | Better repeatability and lower price | ESD-oriented platform and longer reach |
Small-part assembly | Repeatability and payload headroom | Torque sensing and compliant assembly |
Machine tending | Lower price and lighter arm | Longer reach and KUKA machine integration |
Inspection | Consistent camera positioning | Force-sensitive inspection |
Laboratory automation | Python, ROS/ROS 2 and affordability | Advanced HRC and force-control research |
Dispensing | Repeatability and analog I/O | Larger working envelope |
Testing | Lower-cost multi-station deployment | Controlled physical interaction |
Education | Accessible price and open development | Training on premium industrial architecture |
Mobile platform | Lower robot-arm weight | Industrial sensing and KUKA ecosystem |
Human-robot collaboration | Cost-effective collaborative deployment | Integrated joint torque sensors |
Total Cost of Ownership
A robot’s purchase price is only one part of the total project cost.
A complete comparison should include:
Robot arm
Controller
Teach pendant
Required software
End-of-arm tooling
Vision
Safety equipment
Pedestal
Electrical integration
Machine communication
Engineering
Programming
Training
Shipping
Import costs
Commissioning
Preventive maintenance
Spare parts
Technical support
Production downtime
KUKA’s higher robot price can be justified if its platform reduces engineering time, integrates more easily with existing KUKA systems or delivers a force-control capability that would otherwise require external equipment.
FAIRINO’s lower acquisition price can create a stronger return on investment when the process does not require those premium features.
For a manufacturer deploying several simple handling or inspection cells, the FR3’s cost advantage can scale rapidly. For a complex force-controlled assembly station, the KUKA’s torque sensors and engineering ecosystem may reduce project risk enough to offset part of the price difference.

The FR3 is well suited to budget-conscious research using Python, ROS or ROS 2. The KUKA is stronger for research focused on torque sensing, force control, physical human-robot interaction or premium industrial automation.
Does either robot eliminate the need for a risk assessment?
No. Every completed robot application requires a proper risk assessment. The robot, tool, workpiece, process, speed, payload and surrounding equipment must be evaluated together.
Which robot offers better value for money?
The FAIRINO FR3 offers the stronger hardware value for most conventional compact automation applications. The KUKA may justify its higher price when integrated torque sensing, force control, additional reach and KUKA ecosystem compatibility provide measurable engineering or production benefits.
