Kassow Robots KR810 vs RealMan ECO65-B: Robot Comparison
Updated: 2 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE Kassow Robots KR810 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 7- and 6-axis mechanisms also offer different movement options. |
→ CONSIDER Kassow Robots KR810 Consider it when additional load capacity and reach matter. This article compares 10 kg and a 850 mm stated reach; include the gripper and part in the load. |
→ CONSIDER RealMan ECO65-B Consider it when its stated load and reach already cover your task and its controls fit your equipment. This article compares 5 kg and a 610 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. |
Kassow Robots KR810 vs RealMan ECO65-B is a choice about collaborative handling and cell integration. Kassow Robots KR810 and RealMan ECO65-B 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.
Kassow Robots KR810 vs RealMan ECO65-B: quick verdict
Shortlist Kassow Robots KR810 for seven-axis access around fixtures at 10 kg over the documented 850 mm reference. Shortlist RealMan ECO65-B for compact six-axis handling within the 5 kg / 610 mm reviewed envelope. 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 Kassow Robots KR810 against RealMan ECO65-B. 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.
Kassow Robots KR810: design and configuration
The Kassow Robots KR810 is a 7-axis collaborative robot with a payload of 10 kg and a reach of 850 mm, repeatable to ±0.03 mm. Its joints move at 225 deg/s, and the seventh axis lets the arm reach around obstacles and work in confined spaces. The arm mounts on a 130 × 130 mm footprint and is rated IP54. Typical uses include machine tending, dispensing, inspection and pick-and-place in tight cells. The seventh joint provides kinematic redundancy: the arm can change its elbow posture while maintaining a tool pose where the joint limits permit. It does not add payload or make every confined path feasible. Evaluate the elbow motion, cable dress and recovery path at the actual load; qualify the complete collaborative application separately.
RealMan ECO65-B: design and configuration
The RealMan ECO65-B is the standard version of the ECO65, a 6-axis lightweight collaborative arm that carries 5 kg over a 610 mm working radius. Repeatability is ±0.05 mm and the tool centre point moves at up to 1.8 m/s. Weighing 7.8 kg, the arm runs from a 24 V DC supply with a typical draw of 150 W, which makes it practical for mobile and battery-powered platforms. All six joints are fitted with mechanical brakes, and the controller sits inside the 107 mm base.
For this pair, RealMan ECO65-B offers 5 kg over the stated 610 mm reference, compared with 10 kg and 850 mm for Kassow Robots KR810 example. Kassow Robots KR810 has the larger stated distance by 240 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 6 kg below the Kassow Robots KR810 example’s nominal limit and 1 kg below RealMan ECO65-B’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? RealMan ECO65-B is the lower-or-equal nominal payload choice in this pair. Kassow Robots KR810 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. Kassow Robots KR810 provides a stated 850 mm reference, while RealMan ECO65-B provides 610 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 ±0.03 mm for Kassow Robots KR810 and ±0.05 mm for RealMan ECO65-B. 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 Kassow Robots KR810 over RealMan ECO65-B. Use a measured or validated application cycle before assigning a throughput benefit.
Programming, controls and production integration
Kassow Robots KR810 is paired here with the supplied model-specific control package, while RealMan ECO65-B uses Integrated in the robot base. 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. 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
Published arm list prices: Kassow Robots KR810 is listed from $34,000 and RealMan ECO65-B is listed from $11,110. Request configuration-specific quotations for Kassow Robots KR810 and RealMan ECO65-B. 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
Decision gate | Kassow Robots KR810 | RealMan ECO65-B |
|---|---|---|
Strongest documented fit | seven-axis access around fixtures at 10 kg over the documented 850 mm reference | compact six-axis handling within the 5 kg / 610 mm reviewed envelope |
Main boundary | Extra elbow-posture freedom does not increase payload or guarantee collision-free access; validate the complete loaded joint path. | Keep the exact RM or ECO generation, controller features and software package distinct; matching headline dimensions do not make the platforms interchangeable. |
Required approval | Exact Kassow Robots 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 Kassow Robots KR810 when seven-axis access around fixtures at 10 kg over the documented 850 mm reference solves the real constraint and its selected configuration passes the load and access checks. Advance RealMan ECO65-B when compact six-axis handling within the 5 kg / 610 mm reviewed envelope 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
Kassow Robots KR810 has 7 arm axes and RealMan ECO65-B has 6 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 Kassow Robots KR810 vs RealMan ECO65-B, 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?
Kassow Robots KR810 is the stronger starting point for seven-axis access around fixtures at 10 kg over the documented 850 mm reference, while RealMan ECO65-B is worth shortlisting for compact six-axis handling within the 5 kg / 610 mm reviewed envelope. 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 10 kg for the specified Kassow Robots KR810 example and 5 kg for RealMan ECO65-B, subject to all documented load and orientation conditions. Include the tool, adapters, sensors and carried part. Keep the exact RM or ECO generation, controller features and software package distinct; matching headline dimensions do not make the platforms interchangeable.
Does the stated reach guarantee access to my fixture?
No. The comparison gives 850 mm for Kassow Robots KR810 and 610 mm for RealMan ECO65-B 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 ±0.03 mm for Kassow Robots KR810 scope and ±0.05 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 Kassow Robots KR810 and RealMan ECO65-B 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 Kassow Robots KR810 and RealMan ECO65-B. 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.
