ABB Single-arm YuMi IRB 14050 vs DENSO COBOTTA: Cobot Comparison
Updated: 11 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Both are compared at 0.5 kg. ABB Single-arm YuMi IRB 14050 has the longer stated reach, which may help reach separated fixtures; it does not guarantee access at every tool angle. ABB Single-arm YuMi IRB 14050 has 7 axes, compared with 6 axes for DENSO COBOTTA. |
→ CONSIDER ABB Single-arm YuMi IRB 14050 Consider it when extra reach is useful while the compared load capacity is the same. This article compares 0.5 kg with a published reach of 559 mm; include the gripper and part in the load. |
→ CONSIDER DENSO COBOTTA Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 0.5 kg with a published reach of 342.5 mm; 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 Single-arm YuMi IRB 14050 vs DENSO COBOTTA is a buying comparison built around the actual robot configurations, not a collection of family maxima. Both are small-load single-arm solutions, but seven-axis posture flexibility and a wider workspace are different from a very compact integrated robot. The useful result is a cell that meets its load, quality, access and throughput requirements with a maintainable integration plan.
The starting-price figures used here are USD 36,300 for ABB Single-arm YuMi IRB 14050 and USD 15,000 for DENSO COBOTTA, taken from the individual ATC reviews. They are indicative review prices rather than binding current quotations. This guide separates rated payload, published workspace, positioning repeatability and complete-system requirements so that a cheaper or larger arm is not mistaken for a valid finished-cell alternative.
Quick verdict

ABB Single-arm YuMi IRB 14050: Small-part assembly with a 0.5 kg load and seven-axis posture flexibility in a compact working space. This is one arm, not the dual-arm IRB 14000. The 559 mm reach and 0.5 kg rating do not establish equivalent two-handed assembly capability.
DENSO COBOTTA: Very light desktop assembly and inspection with an integrated controller and a compact single-arm layout. Use the general 0.5 kg load rating. The review's 0.7 kg figure is conditional on a downward wrist orientation within ±10 degrees; it is not a universal extra allowance.

The figures refer to the variants discussed in the linked reviews. Joint count and nominal reach do not establish that a complete assembly motion is feasible.
Payload: start with the complete attached tool
The two robots share a 0.5 kg nominal rating. That is a screening boundary for the entire attached load, not a promise that either can carry a 0.5 kg part plus a gripper. Subtract adapters, valves, cables and the complete end effector before allocating part mass. Then check the actual center of gravity, tool moment and inertia against the manufacturer's load conditions.
For this pair, the reviewed masses are 9.6 kg for ABB Single-arm YuMi IRB 14050 and 4 kg for DENSO COBOTTA. Installation mass is separate from tool payload. Include the mounting frame, anchoring, lifting method and service access in the concept. A lighter arm may simplify handling, while a heavier installation may demand a different support structure; neither is a reason to omit dynamic-load and stability checks.
Workspace and posture: check every required pose
ABB Single-arm YuMi IRB 14050 is listed with 559 mm, compared with 342.5 mm for DENSO COBOTTA. These figures are useful for an initial layout but do not by themselves describe the usable workspace of the actual tool. An endpoint may be reachable while its required orientation, approach corridor or escape path is not. Include the machine door, fixture, cables and maximum part envelope in the study.
ABB Single-arm YuMi IRB 14050 has 7 controlled axes, while DENSO COBOTTA has 6. Different joint counts can change posture flexibility and collision avoidance even when the tool endpoints look similar. Demonstrate the real motion, not just a hand-positioned endpoint.
ABB Single-arm YuMi IRB 14050: engineering assessment
The reviewed ABB Single-arm YuMi IRB 14050 combines 0.5 kg rated load with 559 mm and ±0.02 mm positioning repeatability. The seventh joint can help arrange the elbow around a fixture, but it does not increase payload. Assess the complete tool, cable forces and required orientations; small gripper and adapter masses are significant at this load class.
This is one arm, not the dual-arm IRB 14000. The 559 mm reach and 0.5 kg rating do not establish equivalent two-handed assembly capability. For small-part work, gripper mass, fixture compliance and part presentation can dominate the result. Keep the exact single- or dual-arm configuration and controller arrangement in the quotation.
DENSO COBOTTA: where the alternative adds value

The reviewed DENSO COBOTTA offers 0.5 kg rated load, 342.5 mm and ±0.05 mm positioning repeatability. A roughly 4 kg robot can be attractive for a small bench, but the 342.5 mm arm length constrains fixture placement. A short-reach concept may be economical for one task and unsuitable for the same task spread across a wider work surface.
Use the general 0.5 kg load rating. The review's 0.7 kg figure is conditional on a downward wrist orientation within ±10 degrees; it is not a universal extra allowance.
Positioning, force interaction and process quality
The tighter stated position-repeatability value is ±0.02 mm, compared with ±0.05 mm for the other robot. That is a useful shortlist input, not a finished-part tolerance guarantee. Repeatability concerns returning to a pose under specified conditions; absolute accuracy, tool calibration, fixture movement and process variation remain separate engineering concerns.
For assembly, measure seating quality or fastener results; for handling, measure reliable pickup, placement and reject recovery. Use representative production variation rather than one prepared sample. The robot that meets the actual process criterion with the simpler maintained system can be the better choice even when a competing data-sheet figure looks more impressive.
Programming, interfaces and ownership
The ABB source identifies ABB OmniCore. Keep the integrated IRC5 dual-arm arrangement distinct from the separate OmniCore single-arm configuration. A familiar software environment can reduce maintenance friction, but only if the actual team can back up, diagnose and restore the application. Ask for the exact version and the rights to the finished program.
The alternative's reviewed control or HMI arrangement is Integrated controller. Verify the programming interface, licenses, communication options and integration responsibilities in the offered package.
Write an I/O and network schedule for the gripper, PLC, machine, inspection device and safety system. Verify voltages, connector pinouts, signal direction and timeout behavior. A protocol listed in a review is not proof that every license or board is supplied. Include a lost communication link, failed acknowledgement and an interrupted production sequence in the acceptance demonstration.
Safety, environment and real cycle time
Collaborative capability is one element of an application risk assessment. The tool, carried object, machine, hot or sharp process and trapping points may need safeguards beyond the arm's own functions. Establish intended operating modes and validate the completed safety concept with representative operator access. A collaborative label is not permission to assume that fencing or sensing is unnecessary.
The ABB review lists IP30 for the arm. Specify the alternative's exact environmental rating and approved operating conditions in the quotation; do not infer them from its appearance or product class. Ingress ratings do not authorize every cleaning chemical, steam treatment or pressure-washing procedure. Check the controller, cable exits, connectors and tool independently, and distinguish standard protection from a paid option.
Compare useful output using the same part, tool, normal safety settings and peripheral delays. Maximum or typical TCP speeds are not a matched cycle-time benchmark. Gripping, machine dwell, process time and operator visits may dominate. Record good parts, rejected parts, changeover and restart time alongside motion time before turning a supplier demonstration into a payback estimate.
Price and total installed cost
The indicative starting prices are USD 36,300 and USD 15,000, a difference of USD 21,300. The lower-priced arm is DENSO COBOTTA. Those figures come from the linked ATC reviews and may change. They do not establish equivalent controllers, pendants, safety equipment, software, stock or turnkey scope.
Request comparable bills of materials covering the robot, tool, fixture, machine interface, vision, safety devices, controller options, commissioning and training. Include freight, tax and installation where relevant. Name the supplier responsible for diagnosing faults across component boundaries and obtain configuration-specific warranty and delivery commitments. A cheap arm that needs an unsuitable layout changed is not automatically the cheaper installed system.
How to choose for a representative application
Decision | Start by testing | Why it matters |
|---|---|---|
Load and tooling | 0.5 kg versus 0.5 kg | Include all adapters and attached equipment |
Workspace | 559 mm versus 342.5 mm | Match geometric references and tool orientation |
Configuration | 7 versus 6 controlled axes | Do not merge different operating concepts |
Process quality | ±0.02 mm versus ±0.05 mm | Measure the finished result, not only robot position |
Value | USD 36,300 versus USD 15,000 | Align the installed package and maintenance plan |
Both are small-load single-arm solutions, but seven-axis posture flexibility and a wider workspace are different from a very compact integrated robot. For the ABB candidate, the application to demonstrate is: small-part assembly with a 0.5 kg load and seven-axis posture flexibility in a compact working space. For the alternative, evaluate: very light desktop assembly and inspection with an integrated controller and a compact single-arm layout. If a load, pose or safety requirement fails, redesign the concept before judging its apparent purchase-price saving.
Acceptance testing before purchase
Give both suppliers the same workpiece range, complete tool CAD, load data, required poses, target cycle, environmental exposure and intended operator interaction. Agree pass criteria before the trial. Test a missed pickup, a rejected part, a stopped machine and restart after power loss. Ask the intended operator to change a recipe and recover the sequence safely; a supplier-only demonstration is not a maintenance handover.
Retain the program, safety configuration, I/O schedule, tool settings and backup procedure. Establish support escalation, replacement-part responsibilities and the revision of the equipment being supplied. Where contact or dual-arm coordination is involved, keep the demonstrated process settings in the acceptance record so that later changes do not silently invalidate the qualified result.

Frequently asked questions
Which should I choose: ABB Single-arm YuMi IRB 14050 or DENSO COBOTTA?
Both are small-load single-arm solutions, but seven-axis posture flexibility and a wider workspace are different from a very compact integrated robot. Small-part assembly with a 0.5 kg load and seven-axis posture flexibility in a compact working space. Very light desktop assembly and inspection with an integrated controller and a compact single-arm layout. Choose the concept that passes the actual tool-load, workspace, process-quality and safety tests with an acceptable installed quotation and maintenance plan.
What are the indicative starting prices in US dollars?
The ATC reviews list ABB Single-arm YuMi IRB 14050 from USD 36,300 and DENSO COBOTTA from USD 15,000. The difference is USD 21,300. Prices are indicative and may change; confirm the supplied controller, pendant, software, safety equipment, tooling, delivery and integration scope.
Does the payload rating include the gripper?
Yes. Allocate the permitted load to the complete end effector, adapters and carried part, then check moments and inertia. The ratings used here are 0.5 kg and 0.5 kg. A part within the headline rating can still become an excessive load when its tooling is added.
Which has the longer usable workspace?
ABB Single-arm YuMi IRB 14050 lists 559 mm, while DENSO COBOTTA lists 342.5 mm. Verify matching geometric references, tool orientations, approach paths and obstacles. A larger nominal number does not guarantee every required pose or a faster completed cycle.
Does repeatability guarantee the finished-part tolerance?
No. The comparison uses ±0.02 mm for ABB Single-arm YuMi IRB 14050 and ±0.05 mm for DENSO COBOTTA. These positioning figures do not independently establish absolute accuracy or completed-process tolerance. Fixtures, tooling, calibration, part variation and contact behavior must be included in the acceptance test.
Do collaborative robots always work without guarding?
No. The complete application needs risk assessment and validation. Tools, sharp or hot objects, trapping points, neighboring equipment and access patterns may require guarding, sensing, interlocks or speed limits beyond the arm's own functions.
Are all controller and software options included?
Not automatically. The source identifies Integrated controller for DENSO COBOTTA, but only a current quotation defines what is supplied and enabled. Confirm programming tools, protocol licenses, hardware interfaces, backups and ownership of the final application program.
What should the supplier demonstrate before purchase?
Require the real tool, representative parts and normal operating settings. Include critical poses, process quality, a realistic cycle, lost grip or communication, operator interruption and safe restart. Record acceptance criteria and retain the configuration and program used in the successful trial.
Specifications and indicative review prices describe the exact configurations discussed. Confirm the offered revision, package, safety requirements, warranty and delivery with the supplier. This is an editorial buying comparison and does not claim a hands-on performance benchmark.
