Comau MyCo-5-0.80 vs KUKA LBR iiwa 7 R800: Robot Comparison

IN A NUTSHELL

Comau MyCo-5-0.80 vs KUKA LBR iiwa 7 R800 is a choice about collaborative handling and cell integration. Comau MyCo-5-0.80 and KUKA LBR iiwa 7 R800 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.

Comau MyCo-5-0.80 vs KUKA LBR iiwa 7 R800: quick verdict

Shortlist Comau MyCo-5-0.80 for 5 kg collaborative-platform handling within the documented 800 mm working reference. Shortlist KUKA LBR iiwa 7 R800 for seven-axis posture flexibility with 7 kg nominal capacity. Neither is a universal winner: a robot that can carry the load may still fail the fixture-access, controller or maintenance requirements.

The numerical comparison below uses Comau MyCo-5-0.80 against KUKA LBR iiwa 7 R800. 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.

Specifications and exact configuration scope

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.

Comau MyCo-5-0.80: design and configuration

Comau MyCo-5-0.80 is assessed as the named 6-axis configuration with 5 kg payload, 800 mm reach and ±0.02 mm pose repeatability. The 5 kg / 800 mm combination is distinct from both the lighter 950 mm MyCo-3.5 and the larger 1300 mm MyCo-8. Compare the complete gripper and part rather than choosing the arm solely because its model number appears close to an existing fixture requirement. The manufacturer lists a 25 kg arm mass and 180 W typical application consumption; this consumption reference is not peak electrical input or a prediction of energy for the compared task. Standard IP54 and optional IP66 are separate delivered specifications. Floor, ceiling, inclined and wall mounting are listed, but the actual base stiffness, cable route and approved installation conditions still need validation. The published communication package includes TCP/IP and Modbus TCP; PROFINET and EtherNet/IP are identified as options rather than assumed equipment. Graphical programming and a remote calling interface do not, by themselves, establish compatibility with every PLC, vision system or low-level research controller. Match the MyCo control box, software revision, licences and required safety functions to the cell. Include all tooling, workpiece, adapters and services in the moving load, then check wrist moment, inertia and reachable poses. A collaborative platform still requires an application-specific risk assessment: sharp tools, hot parts, crushing points and stopping distances can require guarding or monitored separation. Demonstrate the real loaded cycle and recovery workflow. Published family specifications do not establish local stock, turnkey integration, part accuracy or a delivered application certificate; obtain an exact regional quotation and acceptance plan.

KUKA LBR iiwa 7 R800: design and configuration

The KUKA LBR iiwa 7 R800 is assessed here at the reviewed 7 kg payload and 800 mm working reference, with 7 arm axes, ±0.1 mm repeatability and the Sunrise Cabinet controller scope. The seven-axis iiwa platform has an additional posture degree of freedom and joint torque sensing. It is separate from the six-axis iisy range and its software/control package must be identified in the quotation. Confirm the supported teaching, control interfaces, safety functions and exact tool-load limits; seven joints do not automatically create a safer or faster production cycle.

For this pair, KUKA LBR iiwa 7 R800 offers 7 kg over the stated 800 mm reference, compared with 5 kg and 800 mm for Comau MyCo-5-0.80 example. The stated distances coincide, but the two arms can still have different inner dead zones and approach paths. 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 1 kg below the Comau MyCo-5-0.80 example’s nominal limit and 3 kg below KUKA LBR iiwa 7 R800’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? Comau MyCo-5-0.80 is the lower-or-equal nominal payload choice in this pair. KUKA LBR iiwa 7 R800 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. Comau MyCo-5-0.80 provides a stated 800 mm reference, while KUKA LBR iiwa 7 R800 provides 800 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 Comau MyCo-5-0.80 and ±0.1 mm for KUKA LBR iiwa 7 R800. 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 Comau MyCo-5-0.80 over KUKA LBR iiwa 7 R800. Use a measured or validated application cycle before assigning a throughput benefit.

Programming, controls and production integration

Comau MyCo-5-0.80 is paired here with Dedicated Comau MyCo control box and quoted interface options, while KUKA LBR iiwa 7 R800 uses Sunrise Cabinet. 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.

Configuration and communication detail

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. A collaborative arm does not make an unrestricted-speed application safe. Validate the required speed, force and separation measures with the actual parts. 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

Arm prices: Comau MyCo-5-0.80 is estimated from $28,000 and KUKA LBR iiwa 7 R800 is listed from $50,000. Request configuration-specific quotations for Comau MyCo-5-0.80 and KUKA LBR iiwa 7 R800. 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 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

Advance Comau MyCo-5-0.80 when 5 kg collaborative-platform handling within the documented 800 mm working reference solves the real constraint and its selected configuration passes the load and access checks. Advance KUKA LBR iiwa 7 R800 when seven-axis posture flexibility with 7 kg nominal capacity 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

Comau MyCo-5-0.80 has 6 arm axes and KUKA LBR iiwa 7 R800 has 7 arm axes. A seven-axis arm has an additional posture degree of freedom: the elbow can move while preserving a tool pose where the joint limits permit. This can help around obstacles, but also requires cable and full-path validation. Compare tool detection, sensing, machine I/O and recovery as separate delivered functions.

Industries and application fit

For Comau MyCo-5-0.80 vs KUKA LBR iiwa 7 R800, 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?

Comau MyCo-5-0.80 is the stronger starting point for 5 kg collaborative-platform handling within the documented 800 mm working reference, while KUKA LBR iiwa 7 R800 is worth shortlisting for seven-axis posture flexibility with 7 kg nominal capacity. 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 5 kg for the specified Comau MyCo-5-0.80 example and 7 kg for KUKA LBR iiwa 7 R800, 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 800 mm for Comau MyCo-5-0.80 and 800 mm for KUKA LBR iiwa 7 R800 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 Comau MyCo-5-0.80 scope and ±0.1 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 Comau MyCo-5-0.80 and KUKA LBR iiwa 7 R800 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 Comau MyCo-5-0.80 and KUKA LBR iiwa 7 R800. 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.
