ES3 model positioning and working condition adaptation
ES3 It belongs to the AUBO iS SE Economic Edition and E Education Edition collaborative robot models, with a rated load of 3kg, a motion radius of 625,000mm, and repeatability of ±0.05mm. 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 extra-long reach (625,000mm) is suitable for large workpieces and cross-line services, with attention to stiffness and vibration during large overhanging postures. ± 0.05mm repeatability is the standard level for six-axis industrial robots, covering most working conditions such as welding, handling, palletizing, and loading/unloading. 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 |
| Radius of motion: 625,000mm | 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 |
| Repeatability: ±0.05mm | Repeatability ≠ absolute accuracy: Precision assembly requires external measurement closed-loop or visual guidance; Long-term accuracy trends rely on annual retest management |
| Number of axes: 6 | Six-axis all-posture capability, the preferred choice for complex trajectory and inclined surface operations |
| Protection rating: IP54 | Suitable for standard workshop environments; Dusty and moisture-prone workstations require additional protective kits or positive pressure protection |
| Main body weight: 17kg | Installation 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 ES3 comes with the AUBO control cabinet (i/G series platform) controller, with a programming language and development environment of graphical programming + scripting, and 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.
| Failure mode | Typical performance | Disposal recommendations |
|---|---|---|
| Joint module encoder abnormalities | Joint module encoder abnormalities | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Power unit failure | Power unit failure (sensitive to voltage fluctuations) | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| The teach pendant failed to touch properly | The teach pendant failed to touch properly | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Intermittent interruptions on the EtherCAT bus | Intermittent interruptions on the EtherCAT bus | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Joint temperature and abnormal noise trend checks | According to the manufacturer's manual cycle | Joint temperature and abnormal noise trend checks |
| Power Input Voltage Stability Check (Workshop Power Grid Quality) | According to the manufacturer's manual cycle | Power Input Voltage Stability Check (Workshop Power Grid Quality) |
| Programs and configurations are backed up regularly | Periodically | Programs and configurations are backed up regularly |
| 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 ES3 spare parts?
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 a used ES3 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.
