duAro Collaborative Robot Series · Series technical features
A collaborative dual-arm horizontal multi-joint robot independently developed by Kawasaki can operate at close range with human operators without the need for safety barriers. It makes the implementation of human-machine collaboration simpler and easier to operate, meeting diverse automation needs.
With advanced safety features, it can coexist with humans in environments without safety barriers, making the introduction of small-batch, high-mix-level production lines easier.
Both arms can operate independently or in coordination, working together like a person to complete assembly, handling, loading, and unloading tasks.
Supports tablet teaching or direct teaching, with a low programming threshold and no need for professional robotics engineers.
The compact body design occupies a small footprint and can be flexibly deployed on crowded production lines or test benches.

duAro2 model positioning and working condition adaptation
duAro2 It belongs to the Kawasaki collaborative robot model, with a rated load of 3kg and a motion radius of 785mm. Kawasaki's technical foundation is strong AS language capabilities and deep accumulation in semiconductor cleanliness and welding applications; The control platform is F series (partial) / E series, and the program ecosystem is AS language + teach pendant.
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 processingCommon application processes for this model include assembly, handling, loading and unloading, glue application, polishing, and deburring. The short-arm (785mm) model has a compact structure, suitable for dense workstations and close-range pick-and-place operations, with a small working unit footprint. 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.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Rated load 3kg | It 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: 785mm | Determine 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 |
| Controllers F Series (partial) / E Series | 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 f-series (partial)/E-series controllers supporting duAro2 use AS language + teach pendant as programming language and development environment. 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.
| Failure mode | Typical performance | Disposal recommendations |
|---|---|---|
| 1FB/2FB board failure | 1FB/2FB board fault (driver control board aging) | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| The encoder battery is depleted, causing the origin to be lost | The encoder battery is depleted, causing the origin to be lost | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| The teach pendant's LCD and buttons are aging | The teach pendant's LCD and buttons are aging | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Overcurrent alarm in the driver unit | Overcurrent alarm in the drive unit (motor or load abnormality) | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| The battery is replaced annually | Every year | The battery should be replaced annually, and the original calibration should be performed after replacement |
| Reducer grease should be refilled periodically | By cycle | Reducer grease should be refilled periodically |
| Spare parts for boards and cards are recommended for key customers with in-house redundancy | According to the manufacturer's manual cycle | Spare parts for boards and cards are recommended for key customers with in-house redundancy |
| Cable and drag chain inspection | every six months | Insulation, shielding, and bending radius inspection of power and encoder lines, as well as wear of cables inside the drag chain, are the main causes of intermittent faults |
| Zero point and accuracy retest | Every year | Repeatability measured by dial gauges or laser trackers, drift trend digitization—accuracy degradation can be seen six months in advance |
| Control cabinet dust removal and fans | Every quarter | Filter cleaning, fan speed and noise checks, cabinet temperature recording; Dust environments shorten the cycle |

Common issues with this device
Is it easy to find duAro2 spare parts?
Kawasaki: The spare parts channel for this generation is smooth; we have in-stock or short-cycle channels for standard parts such as drivers, power modules, batteries, and teach pendant components; It is recommended to replace consumables for batteries annually 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 a used duAro2 worth buying?
Second-hand circulation is moderate, and we have accumulated experience in E/F series materials and board-level repair channels. 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.
