FAIRINO ART7-R7 vs. Yaskawa Motoman SDA20F: Dual-Arm Robot Comparison

dual-arm robot comparison • Payload, reach, precision and U.S. pricing

🤖 Overview: The Yaskawa SDA20F from Yaskawa Motoman and the FAIRINO ART7-R7 are both shortlisted for dual-arm automation cells. The Yaskawa Motoman SDA20F offers 20 kg per arm of rated payload, 910 mm horizontal per arm of reach and ±0.1 mm repeatability. The FAIRINO ART7-R7 answers with 7 kg per arm, 714 mm per arm and ±0.03 mm at a published U.S. price of $22,700. This comparison separates published specifications from the points that should be confirmed in a demo or quotation.

Note: The SDA20F is an industrial dual-arm robot rather than a collaborative one: it pairs two 7-axis arms with a rotating waist and normally runs inside a guarded cell, so this comparison focuses on dual-arm capability rather than collaborative operation.

⚖️ Quick Verdict: FAIRINO ART7-R7 vs. Yaskawa Motoman SDA20F

• Choose the FAIRINO ART7-R7 when it keeps the budget low, at a published $22,700.

• Choose the Yaskawa Motoman SDA20F when it offers longer reach, more rated payload.

• Validate both with your real gripper, part mass and layout; installed-cell cost and measured cycle time decide ROI.

📊 FAIRINO ART7-R7 vs. Yaskawa SDA20F Specifications

🏋️ Payload: 7 kg per arm vs. 20 kg per arm

Yaskawa Motoman SDA20F carries 13 kg more rated payload per arm. In practice, payload includes the gripper, adapter plate, sensors and cabling, so the tool consumes a large share of either rating. Ask both suppliers for the payload curve at your tool offset and orientation.

📏 Reach: 714 mm per arm vs. 910 mm horizontal per arm

Yaskawa Motoman SDA20F reaches 196 mm (about 27%) further per arm. Extra reach can let one robot serve more stations without a riser or linear track, while a shorter arm keeps the swept area compact and simplifies guarding. Simulate both robots in your actual cell layout.

🎯 Repeatability and Precision

FAIRINO ART7-R7 publishes the tighter repeatability (±0.03 mm vs. ±0.1 mm). For most tending, packaging and handling work both are sufficient; for tight insertions and vision-guided placement, fixturing, TCP calibration and gripper compliance matter as much as the datasheet figure.

🤝 Dual-Arm Design and Force Control

Both systems use two seven-axis arms for human-like, coordinated manipulation. The SDA20F adds a rotating base axis and carries 20 kg per arm, which suits heavier two-handed assembly and part transfer in a fenced cell. The FAIRINO ART7-R7 is far lighter, builds a torque sensor into every joint for force-controlled, collaborative work, routes cables internally and supports ROS2 plus an SDK for research and physical-AI projects. The trade-off is payload versus collaborative operation, footprint and price.

🛡️ Environment and Safety

The Yaskawa Motoman SDA20F is published at IP54 (IP65/67 versions). FAIRINO lists full-joint brakes and torque sensing for the FAIRINO ART7-R7; request the written protection rating for your configuration. Every application still needs a risk assessment under ISO 10218, and collaborative cells also under ISO/TS 15066.

🏭 Applications Where Each Robot Fits

• Two-handed assembly: both systems coordinate two arms around one part; size each arm's payload against the heaviest part plus gripper.

• Research and physical AI: the FAIRINO ART7-R7 adds ROS2 support, an SDK and torque sensing in every joint for teleoperation and learning projects.

• Part transfer and kitting: compare cell footprint, guarding needs and cycle time with real parts before committing.

💰 Price and Total Cost of Ownership

FAIRINO USA lists the FAIRINO ART7-R7 at $22,700. The Yaskawa Motoman SDA20F is sold by quote, with no public list price. Robot price is only part of the budget: grippers, safety hardware, fixtures, programming, training and spare parts often add as much again, so compare quotes for the same scope.

📈 Illustrative ROI Scenario

Assume both cells need $25,000 for tooling, guarding and integration and each saves $30,000 per year in net labor cost. The FAIRINO ART7-R7 cell would total about $47,700, a simple payback of roughly 1.6 years. These figures are illustrative; model your own cell.

✅ Buyer's Evaluation Checklist

• Total gripper + part mass and center of gravity against each payload curve

• Reach to every pick, place and inspection point in a CAD simulation

• Written IP rating, warranty and delivery terms for the exact revision

• Measured cycle time with real parts, including fault recovery

• Installed-cell quotes for the same scope from both suppliers

🏁 Conclusion

The FAIRINO ART7-R7 stands out for value, with 7 kg per arm payload, ±0.03 mm repeatability and a transparent $22,700 price. The Yaskawa Motoman SDA20F brings longer reach, more rated payload and the Yaskawa Motoman ecosystem. Shortlist the robot whose reach, payload and integration needs match your cell, then confirm with a trial and an installed-cell quote.
