AUBO-i7 vs Mitsubishi Electric ASSISTA RV-5AS-D: quick verdict
Shortlist AUBO-i7 for 7 kg six-axis handling on the AUBO platform. Shortlist Mitsubishi Electric ASSISTA RV-5AS-D for 5 kg collaborative handling within the documented 910 mm reach. Neither is a universal winner: a robot that can carry the load may still fail the fixture-access, controller or maintenance requirements.
AUBO-i7 vs Mitsubishi Electric ASSISTA RV-5AS-D is a choice about collaborative handling and cell integration. AUBO-i7 and Mitsubishi Electric ASSISTA RV-5AS-D 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.
The numerical comparison below uses AUBO-i7 against Mitsubishi Electric ASSISTA RV-5AS-D. 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.
AUBO-i7: design and configuration
The AUBO Robotics AUBO-i7 is a six-axis collaborative robot arm with a payload of 7 kg, a reach of 786.5 mm and repeatability of ±0.02 mm. It is designed for tasks that need more payload within a compact working envelope, such as machine tending, assembly, pick and place, screwdriving and dispensing. The arm weighs 24 kg. It runs on the AUBO CB-M control box and communicates over TCP/IP, Modbus RTU/TCP and PROFINET, with SDK and ROS support for integration. The AUBO-i hardware has six rotating joints and a model-specific load-deflection limit. The source review describes a CB-M control box; the current AUBO-i manual identifies CB-iS controllers, so match the arm and control generation explicitly. Power-and-force limits depend on the full application, tool contact geometry and safety settings, and do not prove unrestricted operation next to people.
Mitsubishi Electric ASSISTA RV-5AS-D: design and configuration
The Mitsubishi Electric MELFA ASSISTA RV-5AS-D is a 6-axis collaborative robot with a 5 kg rated payload, a 910 mm reach and ±0.03 mm repeatability. It is designed to work alongside operators without safety fencing, moving at up to 250 mm/s in collaborative operation and up to 1,000 mm/s in high-speed operation. The IP54 arm suits assembly, machine tending, inspection and pick-and-place tasks. The arm weighs 32 kg, mounts on the floor or ceiling and runs on the CR800-05VD controller.
For this pair, Mitsubishi Electric ASSISTA RV-5AS-D offers 5 kg over the stated 910 mm reference, compared with 7 kg and 786.5 mm for the AUBO example. Mitsubishi Electric ASSISTA RV-5AS-D has the larger stated distance by 123.5 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 4 kg: a 1 kg tool and adapter package carrying a 3 kg part or product group. This arithmetic leaves 3 kg below the AUBO-i7 example’s nominal limit and 1 kg below Mitsubishi Electric ASSISTA RV-5AS-D’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 ASSISTA RV-5AS-D is the lower-or-equal nominal payload choice in this pair. AUBO-i7 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. AUBO-i7 provides a stated 786.5 mm reference, while Mitsubishi Electric ASSISTA RV-5AS-D provides 910 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 assembly and machine tending, test the gripper jaws in their open and closed positions. Include feeder replenishment, rejected-part disposal and tool changes. Check wrist flips and singularity avoidance along the whole path. A compact robot can fit a small fixture well, while a longer arm can simplify station placement; neither geometric benefit can be assumed without the actual model.
Precision and throughput: compare the same task
The comparison uses ±0.02 mm for AUBO-i7 and ±0.03 mm for Mitsubishi Electric ASSISTA RV-5AS-D. 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 AUBO-i7 over Mitsubishi Electric ASSISTA RV-5AS-D. Use a measured or validated application cycle before assigning a throughput benefit.
Programming, controls and production integration
The AUBO-i review baseline uses a CB-M control package, while current manufacturer documentation identifies the CB-iS controller family. Match the actual arm and control generation before choosing software or industrial communication options. Mitsubishi ASSISTA uses its dedicated CR800-05VD package; confirm the supplied teaching workflow and PLC interface.
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.
For a collaborative application, safe operation is a property of the complete installation and task. Include sharp edges, clamping points, workpiece retention, tool temperature, possible contact and restart behavior. Built-in arm safety functions do not establish that a particular tool can work next to a person at unrestricted speed. Validate application limits and any required safeguarding with the actual parts and process.
Price and lifecycle value
The source reviews list starting references of USD 22,800 for AUBO-i7 and USD 34,000 for Mitsubishi Electric ASSISTA RV-5AS-D. These are historical editorial starting references, not current sales offers, confirmed stock or matched quotations. Revision, supply condition and included controller can change the relevant price. Request a written quotation naming the arm, controller, pendant, cables, software options, warranty and commissioning scope.
Compare the installed production scope: tool, fixtures, sensing, guarding, machine interface, programming, acceptance and training. For small-parts automation, include feeders, vision calibration, nests and rejected-part handling. 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 | AUBO-i7 | Mitsubishi Electric ASSISTA RV-5AS-D |
|---|---|---|
Strongest documented fit | 7 kg six-axis handling on the AUBO platform | 5 kg collaborative handling within the documented 910 mm reach |
Main boundary | Tool mass, wrist moments and access constrain the headline specification. | Confirm exact configuration, controller, wrist loading and installation envelope. |
Required approval | Exact AUBO model and controller, 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 AUBO-i7 when 7 kg six-axis handling on the AUBO platform solves the real constraint and its selected configuration passes the load and access checks. Advance Mitsubishi Electric ASSISTA RV-5AS-D when 5 kg collaborative handling within the documented 910 mm reach 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.
Frequently asked questions
Which robot is better for this application?
AUBO-i7 is the stronger starting point for 7 kg six-axis handling on the AUBO platform, while Mitsubishi Electric ASSISTA RV-5AS-D is worth shortlisting for 5 kg collaborative handling within the documented 910 mm reach. 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 7 kg for the specified AUBO-i7 example and 5 kg for Mitsubishi Electric ASSISTA RV-5AS-D, 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 786.5 mm for AUBO-i7 and 910 mm for Mitsubishi Electric ASSISTA RV-5AS-D 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 ±0.02 mm for the AUBO scope and ±0.03 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.
Are the review starting prices current purchase quotations?
No. From USD 22,800 and USD 34,000 are historical references from the linked ATC reviews. They are not current matched offers and do not establish stock or the installed-cell cost. Obtain configuration-specific quotations with the controller, software, tooling, safety and commissioning scope itemized.
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 AUBO-i7 and Mitsubishi Electric ASSISTA RV-5AS-D. Check production timing, settling, interruptions and recovery. Include the most difficult loaded approach and retreat. Approve the exact delivered configuration and preserve its final settings.
