- 13 min read
The FAIRINO FR3 and AUBO i3 are both compact six-axis collaborative robots designed for small workspaces, light assembly, small-part pick and place, machine loading, inspection, education, research, dispensing, and compact automation cells.
This is a clean comparison because both robots are in the 3 kg payload class and have very similar reach.
The FAIRINO FR3 is a value-focused compact cobot with a lower public U.S. price, better published repeatability, 5 kg published maximum payload headroom, optional IP65 protection, and complete Product structured data with a numeric price.
The AUBO i3 is a compact open-platform cobot with open SDK support, TCP/IP and Modbus communication, ROS / Linux / Windows integration, 625 mm reach, and a public European marketplace price of €18,100 excl. VAT.
The clean comparison is:
FAIRINO FR3 = lower price, better repeatability, stronger ROI, 5 kg max published payload, and public U.S. buying path.
AUBO i3 = open SDK, open communication, slightly longer reach, and open-platform integration workflow.

Price Comparison
Robot | Public Price | Price Source Type |
FAIRINO FR3 | $6,799 | FAIRINO USA public listed price |
AUBO i3 | €18,100 excl. VAT | Public marketplace price |
AUBO i3 alternative supplier range | $15,000–$16,500 | Public supplier range, not official MSRP |
The FAIRINO FR3 has the clearer and lower public U.S. price. AUBO i3 pricing appears in public marketplace/supplier listings, but it is not a single official manufacturer MSRP. The strongest comparable public number from a European marketplace is €18,100 excl. VAT, while a separate public supplier listing shows a $15,000–$16,500 USD range.
Even using the lower USD supplier range, the FAIRINO FR3 remains significantly less expensive than AUBO i3.
Main Technical Comparison
Payload
Robot | Payload |
FAIRINO FR3 | 3 kg nominal / 5 kg max published |
AUBO i3 | 3 kg |
Both robots are 3 kg-class collaborative robots.
The difference is that FAIRINO publishes a 5 kg maximum payload figure for the FR3. That maximum should be validated for load center, tool weight, robot pose, speed, and duty cycle before final engineering use.
Payload verdict: Equal at nominal payload; FAIRINO FR3 has more published maximum payload headroom.
Reach
Robot | Reach |
FAIRINO FR3 | 622 mm |
AUBO i3 | 625 mm |
The AUBO i3 has 3 mm more reach than the FAIRINO FR3. This is technically an advantage, but it is too small to change most automation layouts.
Reach verdict: AUBO i3 wins slightly, but the difference is minimal.
Repeatability
Robot | Repeatability |
FAIRINO FR3 | ±0.02 mm |
AUBO i3 | 0.05 mm |
FAIRINO FR3 has the stronger published repeatability. This matters for small-part pick and place, dispensing, light assembly, screwdriving, inspection positioning, and electronics-related automation.
Repeatability verdict: FAIRINO FR3 wins.
Speed
Robot | Speed |
FAIRINO FR3 | 1 m/s typical TCP speed |
AUBO i3 | 1.9 m/s max linear TCP speed |
The AUBO i3 has the higher published maximum linear TCP speed in the marketplace specifications. FAIRINO publishes a typical TCP speed of 1 m/s. Real production cycle time depends on payload, path design, acceleration, gripper timing, safety configuration, and operator proximity.
Speed verdict: AUBO i3 wins on published maximum speed.
Robot Weight
Robot | Robot Weight |
FAIRINO FR3 | approx. 15 kg |
AUBO i3 | 16 kg |
FAIRINO FR3 is slightly lighter based on the listed values.
Weight verdict: FAIRINO FR3 wins slightly.
IP Rating
Robot | IP Rating |
FAIRINO FR3 | IP54 standard / IP65 optional |
AUBO i3 | IP54 appears in supplier listing; teach panel IP43 in marketplace spec |
FAIRINO has the stronger protection story because FR3 is listed as IP54 with optional IP65. AUBO i3 supplier listings show IP54, while the Unchained Robotics page lists the teach panel as IP43.
IP rating verdict: FAIRINO FR3 wins if optional IP65 is required.
