IN A NUTSHELL

🔎 THE KEY DIFFERENCE

ABB IRB 660 has the higher stated load capacity and longer stated reach. Those figures help shortlist it for heavier loads or wider layouts, but do not prove a faster production cycle. Their 4- and 5-axis mechanisms also offer different movement options.

→ CONSIDER ABB IRB 660

Consider it when additional load capacity and reach matter. This article compares 250 kg and a 3,150 mm stated reach; include the gripper and part in the load.

→ CONSIDER Kawasaki RD080N

Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 80 kg and a 2,100 mm stated reach; include the gripper and part in the load.

💡 THE TAKEAWAY

Check the required tool angles and approach path: different axis counts change movement options. Choose only after both suppliers demonstrate the loaded task and quote the same complete installation.

ABB IRB 660 vs Kawasaki RD080N is a choice about palletizing and load orientation. ABB IRB 660 and Kawasaki RD080N differ in their working envelope, loading assumptions and engineering ecosystem. A useful decision starts with the exact mechanism and process, then checks whether either robot can execute the required path with the real tool attached. This comparison separates documented specifications from application-level engineering judgments.


ABB IRB 660 vs Kawasaki RD080N: quick verdict


Shortlist ABB IRB 660 for 250 kg palletizing within the named 3150 mm envelope and 4-axis architecture. Shortlist Kawasaki RD080N for 80 kg palletizing within the named 2100 mm envelope and 5-axis architecture. First decide whether the product stays level or must be tilted. A payload match does not remove an architectural difference between four and six axes.


The numerical comparison below uses ABB IRB 660 against Kawasaki RD080N. The stated model scope matters when comparing later revisions or differently equipped installations. Published repeatability describes return to a taught position under specified conditions; it does not establish complete-cell accuracy or prove a faster production cycle.

Read the reach row together with the geometric notes below. Manufacturers may specify an arm-link sum, a wrist-centre motion area or reach to the flange; those dimensions are not interchangeable. The table does not establish access to every point at every tool angle. Controller references identify reviewed packages, and actual compatibility must be confirmed by model, software version and region.


ABB IRB 660: design and configuration


The IRB 660 is a four-axis palletizing robot with a 180 kg or 250 kg payload, a 3150 mm reach and ±0.05 mm repeatability. Its long reach lets one robot serve several infeed conveyors and pallet stations.

Kawasaki RD080N: design and configuration


The Kawasaki RD080N is a 5-axis palletizing robot with an 80 kg payload, a reach of 2100 mm and a positional repeatability of ±0.07 mm. It is a compact palletizing robot designed for installation in confined spaces. The robot weighs 540 kg, is floor-mounted and runs on the Kawasaki F03 controller. The RD080N runs on the F03 controller and is programmed from the teach pendant in Kawasaki's AS language. Kawasaki's K-ROSET software is available for offline programming and simulation. The controller, end effectors, safety equipment and integration affect the final price and are quoted separately. Prices are indicative, are not final and may change. Keep the exact suffix, controller generation, wrist load diagram and protection package in the order scope. A different family member’s reach, high-speed rating or controller options must not be transferred to this configuration.


For this pair, Kawasaki RD080N offers 80 kg over the stated 2100 mm reference, compared with 250 kg and 3150 mm for ABB IRB 660 example. ABB IRB 660 has the larger stated distance by 1050 mm, but this difference is only a preliminary layout indicator because reference points and joint envelopes can differ. Locate the actual fixture in each manufacturer model before treating this as usable extra working space.


Payload, tooling and a worked load example


Consider an illustrative total wrist load of 64 kg: a 16 kg tool and adapter package carrying a 48 kg part or product group. This arithmetic leaves 186 kg below the ABB IRB 660 example’s nominal limit and 16 kg below Kawasaki RD080N’s nominal limit. These are mass differences, not safety factors or a validated load approval. A heavy camera, valve block or retained material must be included before recalculating the total.


The example exposes the practical question: is the application limited by mass, by tool offset or by wrist rotation? Kawasaki RD080N is the lower-or-equal nominal payload choice in this pair. ABB IRB 660 offers more or equal headline mass capacity, but that alone cannot approve an eccentric fixture. Moving the same mass farther from the flange increases the moment, and spreading it increases rotational inertia. Manufacturer load diagrams and the actual centre of gravity govern the final allowable motion.


Model the empty, partly loaded and fully loaded tool states separately. A vacuum layer gripper, a weld torch with hoses or an inspection head may change its effective loading during the cycle. Set the controller’s load data for each supported state and validate the transition logic. A payload table cannot predict acceleration derating, cable pull or transient reactions at a machine interface.


Reach, orientation and fixture access


Build the same cell model for both candidates: base height, machine opening, fixture datum, maximum part size, tool extension and access for maintenance. ABB IRB 660 provides a stated 3150 mm reference, while Kawasaki RD080N provides 2100 mm. Check the deepest production pose and the return path with the loaded tool. An arm that just touches the target at full extension may have little freedom left to turn, retract or avoid a door.


Distinguish the required load attitude from the robot’s headline axis count. A four-axis palletizer handles level positioning and vertical-axis rotation. A five-axis palletizing wrist can support an additional attitude adjustment within its own joint limits, while a six-axis handling arm provides a different orientation envelope. Simulate the lowest pickup, highest layer, farthest corner and loaded exit rather than treating these mechanisms as interchangeable.


Precision and throughput: compare the same task


The comparison uses ±0.05 mm for ABB IRB 660 and ±0.07 mm for Kawasaki RD080N. These figures should be read in their documented configuration scope. Repeatability is not absolute accuracy, camera calibration accuracy or finished-part capability. Fixture variation, TCP calibration, thermal conditions and tool compliance can dominate the error at the process point, especially when the tool extends far from the flange.


Ask each integrator to execute the same representative path with the same payload model, tool length, process dwell and stop conditions. Report transfer time, settling time, process time and waiting time separately. Published standard cycles often use different loads and distances; dividing one catalogue cycle by another would not establish the production advantage of ABB IRB 660 over Kawasaki RD080N. Use a measured or validated application cycle before assigning a throughput benefit.


Programming, controls and production integration


ABB IRB 660 is paired here with ABB IRC5 or OmniCore, while Kawasaki RD080N uses F03. Controller names identify the review baseline rather than a guarantee that all interface options are included. Compare the actual software revision, teaching workflow, diagnostic tools, fieldbus licences and recovery procedures. An existing trained team and reusable production code may outweigh a small dimensional advantage. Obtain a demonstration of the same machine handshake and interrupted-cycle recovery on both platforms.


Specify the PLC handshakes before ordering: cycle request, ready, busy, complete, fault, part present and recovery authorization. Define how an interrupted operation resumes without repeating a dangerous or quality-critical action. Vision, force sensing, fieldbus communication and external-axis coordination must be checked as explicit included or optional functions. An Ethernet connector does not by itself prove that a particular industrial protocol or software interface is licensed and supported.

Protection, installation and maintenance


Match the precise protection package to the process. Standard, protected, cleanroom, foundry and washing configurations can have different seals, services and maintenance requirements. Do not transfer the best optional IP or cleanroom rating to an unprotected base model. Check the controller location, cable bend radius, available lifting access and base reactions with the installer.


Treat safe operation as a property of the complete task and installation. Include the tool, sharp workpiece edges, trapping points, dropped loads and machine access. These robot systems require task-specific safeguarding; payload or compact size does not establish safe unguarded operation. Plan tool replacement and fault recovery without dismantling the whole installation, and include connector access, lubrication and spare-cable replacement in the maintenance layout.


Price and lifecycle value


Published arm list prices: ABB IRB 660 is listed from $75,000 and Kawasaki RD080N is listed from $55,500. Request configuration-specific quotations for ABB IRB 660 and Kawasaki RD080N. An arm-only number is not the price of a commissioned production cell. Ask for separate line items for controller, pendant, communication options, end effector, safety equipment, installation, acceptance, training and warranty. Price changes, regional support and included software can reverse an apparent hardware-cost advantage. Compare the same delivered scope before calculating payback.


Compare the installed production scope: tool, fixtures, sensing, guarding, machine interface, programming, acceptance and training. For palletizing, include infeed control, pallet detection, load retention and gripper services. Keep purchase cost and recurring support costs separate. No payback figure is defensible until the actual cycle, yield, utilization and installation quotation are known.


Selection and acceptance plan


Decision gate

ABB IRB 660

Kawasaki RD080N

Strongest documented fit

250 kg palletizing within the named 3150 mm envelope and 4-axis architecture

80 kg palletizing within the named 2100 mm envelope and 5-axis architecture

Main boundary

Four arm axes position and rotate a level load; they do not provide arbitrary pitch and roll. Validate complete gripper inertia, load retention and the full pallet pattern.

The five-axis palletizing wrist has its own attitude limits; do not assume every six-axis tool pose or transfer another model’s load chart.

Required approval

Exact ABB variant, tool load and validated process path

Exact competitor revision, tool load and validated process path

Acceptance evidence

Agreed parts, path, quality and recovery results

The same agreed parts, path, quality and recovery results


Advance ABB IRB 660 when 250 kg palletizing within the named 3150 mm envelope and 4-axis architecture solves the real constraint and its selected configuration passes the load and access checks. Advance Kawasaki RD080N when 80 kg palletizing within the named 2100 mm envelope and 5-axis architecture provides the more suitable process arrangement. Reject either candidate if a mandatory pose, protection requirement or controller function cannot be demonstrated. A purchasing shortlist should preserve these conditions instead of converting a single catalogue advantage into a blanket recommendation.


Before acceptance, agree the representative parts, tool states, operating sequence and quality criteria with both suppliers. Demonstrate cold start, normal production, rejected parts, interrupted cycles and controlled recovery. Record the final tool data and software backup. This turns the comparison into a repeatable purchasing decision and helps prevent a later fixture change from invalidating the original robot selection.


Motion architecture and functionality


ABB IRB 660 has 4 arm axes and Kawasaki RD080N has 5 arm axes. A four-axis mechanism cannot independently supply every pitch and roll angle. Assess whether the tool must stay level or be presented at varying attitudes. Compare tool detection, sensing, machine I/O and recovery as separate delivered functions.


Industries and application fit


For ABB IRB 660 vs Kawasaki RD080N, use the actual part and process as the industry filter. Electronics, manufactured-component handling and machine tending are candidate uses when their tool mass, access and quality requirements fit the documented configurations. These are application-selection judgments, not claims that either exact model is installed at a named customer. A food, medical-device or clean-production application additionally requires the correct material, lubrication and protection package; the base model name does not establish hygienic or cleanroom compliance.

Frequently asked questions


Which robot is better for this application?


ABB IRB 660 is the stronger starting point for 250 kg palletizing within the named 3150 mm envelope and 4-axis architecture, while Kawasaki RD080N is worth shortlisting for 80 kg palletizing within the named 2100 mm envelope and 5-axis architecture. The final choice depends on the real loaded path, required protection, controls and acceptance results. Neither a higher payload nor a longer reach establishes a universal winner.


What payload should I use for the comparison?


Use 250 kg for the specified ABB IRB 660 example and 80 kg for Kawasaki RD080N, subject to all documented load and orientation conditions. Include the tool, adapters, sensors and carried part. The five-axis palletizing wrist has its own attitude limits; do not assume every six-axis tool pose or transfer another model’s load chart.


Does the stated reach guarantee access to my fixture?


No. The comparison gives 3150 mm for ABB IRB 660 and 2100 mm for Kawasaki RD080N using the stated model references. Joint limits, reach reference points, wrist orientation, tool length and collisions determine whether the actual fixture is accessible. Simulate the full approach and exit path.


Can I use the best specifications from every family variant?


No. Keep each named model and revision intact. A different arm length, controller generation or protection option can change the relevant specification. Do not combine one version’s maximum payload with another version’s maximum reach.


Is repeatability the same as finished-part accuracy?


No. The stated values are ±0.05 mm for ABB IRB 660 scope and ±0.07 mm for the competitor scope. Finished-part results also depend on fixtures, TCP calibration, sensing, thermal conditions and tool compliance. Validate the actual process instead of treating catalogue repeatability as a complete accuracy guarantee.


How should purchase prices be compared?


Use current written quotations for ABB IRB 660 and Kawasaki RD080N with the same arm, controller, software, tooling and commissioning scope. This comparison does not represent an ATC sales offer or stock confirmation. Historical review figures are not a substitute for a configuration-specific purchase quotation.


Can these robots operate safely next to people without guarding?


These specifications do not establish a safe unguarded installation. Assess the complete task, tool, load and machine interface, then implement and validate the required safeguarding and operating procedures. Do not infer collaborative operation from a compact arm, limited payload or education setting.


What should an acceptance test compare?


Use the same parts, actual tool load, fixture locations, path and quality criteria for ABB IRB 660 and Kawasaki RD080N. Check production timing, settling, interruptions and recovery. Include the highest layer and farthest pallet corner. Approve the exact delivered configuration and preserve its final settings.
