AUBO-iS3 model positioning and working condition adaptation

AUBO-iS3 It belongs to the AUBO Intelligent collaborative robot model, with a rated load of 3kg, a motion radius of 625mm, and a repeatability of ±0.02mm. AUBO Intelligent's technical foundation is a pioneer in domestic collaborative robots. The classic i series platform is mature, and the G series pushes collaborative payloads to 25–35kg; The control platform is the AUBO control cabinet (i/G series platform), with a program ecosystem of graphical programming + scripts, and an open ROS interface.

From the perspective of working condition adaptation, typical applications for small load (3kg) positioning are:High-speed sorting, precision assembly, dispensing coating, and inspection/pick-and-place processing。 The short arm (625mm) model has a compact structure, suitable for dense workstations and close-range pick-and-place operations, with a small work unit footprint. ± 0.02mm repeatability is the standard level for six-axis industrial robots, covering the vast majority of welding operations, handling, palletizing, and loading and unloading operations. Although the load is light, it is recommended to keep the total weight of the end and workpiece within 70% of the rated value, leaving ample acceleration margin at high speeds.

Engineering implications of the AUBO-iS3 specification parameters
ParametersEngineering interpretation and usage recommendations
Rated load 3kgIt is recommended to reserve a load margin of 20%–30%; Verification is made by combining end self-weight + workpiece + imbalanced load inertia, especially sensitive to high-speed conditions
Movement radius: 625mmDetermine the radius of the workcell layout: bins, tooling, and fences are bounded by maximum arm span + safety distance; Verify the accessibility of each pick-and-place point during cross-station service
Repeatability: ±0.02mmRepeatability ≠ absolute accuracy: Precision assembly requires external measurement closed-loop or visual guidance; Long-term accuracy trends rely on annual retest management
Number of axes: 6Six-axis all-posture capability, the preferred choice for complex trajectory and inclined surface operations
Protection rating: IP67Resistant to dust and washing environments (suitable for food and beverage, casting and grinding stations)
Main body weight: 16kgInstallation base and foundation load-bearing check based on weight + dynamic load; Floor slab installation requires structural calculation, with heavy-duty models serving as independent foundations
Controller: AUBO control cabinet (i/G series platform)Decide on the process ecosystem, spare parts channels, and second-hand residual value; Currently, spare parts channels are smooth, and repair and upgrade paths are mature

Control systems and common failure modes

The AUBO control cabinet (i/G series platform) controller supported by the AUBO-iS3 features a programming language and development environment of graphical programming + scripting, with an open ROS interface. Maintenance of this generation of control platforms focuses on three basic components: power, storage, and cooling—most "sudden downtime" can be detected in advance when preventive maintenance is in place.

Common issues with this device

Is it easy to find spare parts for the AUBO-iS3?

AUBO Intelligent: Spare parts channels for this generation are smooth; for regular parts such as drivers, power modules, batteries, and teach pendant components, we have in-stock or short-cycle channels; Joint temperature and abnormal noise trends Inspection consumables are recommended to be configured according to the annual maintenance contract.

With a rated load of 3kg, how much weight can it actually handle?

The rated load is the static load limit of the flange surface. In actual selection, three factors must be considered: the self-weight of the end fixture (vacuum suction cup groups or grippers often account for 2–5kg), the inertia generated by the workpiece offload (checked according to the inertia ratio when the center of gravity deviates from the flange center), and the dynamic load during high-speed movement. The conventional engineering practice is to keep the "end + workpiece" within 70%–80% of the rated value to ensure cycle time and service life.

If the equipment's accuracy deteriorates after several years of use, how can it be restored?

According to the inspection order: first check whether the zero point is drifting (common after collision or battery depletion), then perform zero calibration; Check the reducer's return error (actual measurement of forward and reverse positioning deviation; if exceeded, disassemble or replace); Then check the installation base fastening and foundation settlement; Finally, trajectory compensation parameter restructuring. Most accuracy issues can be mostly restored after calibration and maintenance, so there is no need to rush into major repairs—we first release the inspection data before deciding on the plan.

Is the used AUBO-iS3 worth buying?

The i series has a large supply of second-hand materials and comprehensive materials, offering cost-effective options for collaborative palletizing and loading/unloading conditions. Three essential items for second-hand procurement: comprehensive inspection reports (axial accuracy, driver status, insulation and battery), maintenance history and operating hours, controller generation, and software license integrity. Every used machine we sell comes with inspection records and a 12-month warranty, and we can also accept third-party inspections designated by customers.
