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.
Kawasaki BA013N: design and configuration
The Kawasaki BA013N is a 6-axis arc welding robot with a 13 kg payload, a reach of 1492 mm and a positional repeatability of ±0.04 mm. It is designed for arc welding of metal parts and assemblies. The robot weighs 260 kg and mounts on the floor or the ceiling. 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.
Mitsubishi Electric RV-12CRL: design and configuration
The Mitsubishi Electric MELFA RV-12CRL is a 6-axis vertical articulated robot with a 12 kg payload, a 1504 mm reach and ±0.04 mm repeatability. It is the long-reach model of the compact RV-CR series and is built for machine tending, material handling, packaging and assembly of larger workpieces. The arm is rated IP65. It weighs 110 kg, mounts on the floor or ceiling and runs on the CR800-12CVD controller. The reviewed MELFA model is kept separate from its longer-arm derivatives and other controller packages. Confirm whether the supplied CR controller is standalone or integrated with the intended Mitsubishi control platform. For a deep fixture, compare the complete wrist approach and retreat, rather than maximum reach alone.
For this pair, Mitsubishi Electric RV-12CRL offers 12 kg over the stated 1504 mm reference, compared with 13 kg and 1492 mm for Kawasaki BA013N example. Mitsubishi Electric RV-12CRL has the larger stated distance by 12 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 9.6 kg: a 2.4 kg tool and adapter package carrying a 7.2 kg part or product group. This arithmetic leaves 3.4 kg below the Kawasaki BA013N example’s nominal limit and 2.4 kg below Mitsubishi Electric RV-12CRL’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? Mitsubishi Electric RV-12CRL is the lower-or-equal nominal payload choice in this pair. Kawasaki BA013N 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. Kawasaki BA013N provides a stated 1492 mm reference, while Mitsubishi Electric RV-12CRL provides 1504 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.
For the welding comparison, include the actual torch angle, nozzle length, seam approach and cable package. Simulate seam starts and ends as well as continuous travel. A pose that looks accessible with an empty flange may become blocked after the torch, wire feeder and fixtures are installed. Validate touch sensing or seam-tracking options only where they are part of the supplied package.
Precision and throughput: compare the same task
The comparison uses ±0.04 mm for Kawasaki BA013N and ±0.04 mm for Mitsubishi Electric RV-12CRL. 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 Kawasaki BA013N over Mitsubishi Electric RV-12CRL. Use a measured or validated application cycle before assigning a throughput benefit.
Programming, controls and production integration
Kawasaki BA013N is paired here with Confirm offered Kawasaki controller, while Mitsubishi Electric RV-12CRL uses CR800-12CVD. 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: Kawasaki BA013N is listed from $37,300 and Mitsubishi Electric RV-12CRL is listed from $26,300. Request configuration-specific quotations for Kawasaki BA013N and Mitsubishi Electric RV-12CRL. 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 welding, include the power source, wire feed, torch cleaning, extraction and seam options. 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 | Kawasaki BA013N | Mitsubishi Electric RV-12CRL |
|---|---|---|
Strongest documented fit | arc-welding access using the named 13 kg / 1492 mm process-arm configuration | 12 kg industrial handling within the documented 1504 mm working reference |
Main boundary | Torch, cables, wire feed, power-source interface and seam recovery must match the quoted package; arm geometry does not supply a complete welding cell. | Confirm exact configuration, controller, wrist loading and installation envelope. |
Required approval | Exact Kawasaki 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 Kawasaki BA013N when arc-welding access using the named 13 kg / 1492 mm process-arm configuration solves the real constraint and its selected configuration passes the load and access checks. Advance Mitsubishi Electric RV-12CRL when 12 kg industrial handling within the documented 1504 mm working reference 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
Kawasaki BA013N has 6 arm axes and Mitsubishi Electric RV-12CRL has 6 arm axes. Both have six arm axes; equal axis counts do not establish equal joint travel, inner workspace or fixture access. Compare tool detection, sensing, machine I/O and recovery as separate delivered functions.
Industries and application fit
For Kawasaki BA013N vs Mitsubishi Electric RV-12CRL, 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.

Kawasaki BA013N is the stronger starting point for arc-welding access using the named 13 kg / 1492 mm process-arm configuration, while Mitsubishi Electric RV-12CRL is worth shortlisting for 12 kg industrial handling within the documented 1504 mm working reference. 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 13 kg for the specified Kawasaki BA013N example and 12 kg for Mitsubishi Electric RV-12CRL, subject to all documented load and orientation conditions. Include the tool, adapters, sensors and carried part. Confirm exact configuration, controller, wrist loading and installation envelope.
Does the stated reach guarantee access to my fixture?
No. The comparison gives 1492 mm for Kawasaki BA013N and 1504 mm for Mitsubishi Electric RV-12CRL 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 ±0.04 mm for Kawasaki BA013N scope and ±0.04 mm for the competitor scope. Finished-part results also depend on fixtures, TCP calibration, sensing, thermal conditions and tool compliance.
