Neuromeka Indy7 vs Productive Robotics OB7 Stretch: Robot Comparison
Updated: 2 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This is a load-versus-reach trade-off: Neuromeka Indy7 has the higher stated load capacity, while Productive Robotics OB7 Stretch has the longer stated reach. Start with the constraint your task actually has. Their 6- and 7-axis mechanisms also offer different movement options. |
→ CONSIDER Neuromeka Indy7 Consider it when additional load capacity matters more than extra reach. This article compares 7 kg and a 800 mm stated reach; include the gripper and part in the load. |
→ CONSIDER Productive Robotics OB7 Stretch Consider it when reaching farther matters more than the higher payload of the alternative. This article compares 4 kg and a 1,250 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. |
Neuromeka Indy7 vs Productive Robotics OB7 Stretch is a choice about collaborative handling and cell integration. Neuromeka Indy7 and Productive Robotics OB7 Stretch 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.
Neuromeka Indy7 vs Productive Robotics OB7 Stretch: quick verdict
Shortlist Neuromeka Indy7 for seven-kilogram handling within the reviewed 800 mm maximum-load scope. Shortlist Productive Robotics OB7 Stretch for seven-axis posture flexibility with 4 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 Neuromeka Indy7 against Productive Robotics OB7 Stretch. 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.
Neuromeka Indy7: design and configuration
The reviewed Indy7 is a six-axis, 7 kg collaborative arm. This comparison uses an 800 mm loaded working reference rather than combining a separately reported 1300 mm envelope with the full payload. Confirm the exact Indy7 generation and load diagram: current Indy7 variants and historical geometry references must not be mixed. Its impedance-control teaching workflow is relevant to handling and machine tending, while the real tool and installation still require their own safety assessment.
Productive Robotics OB7 Stretch: design and configuration
The Productive Robotics OB7 Stretch is a 7-axis collaborative robot that carries 4 kg over a 1250 mm reach. It is a longer-reach version of the standard OB7 and is widely used for tending lathes. At 22 kg the arm is light enough for cart or pedestal mounting on a 220 mm flange, and it repeats to ±0.1 mm. Programming is done by demonstration from a tablet, with EtherNet/IP, TCP/IP and Modbus available for machine communication.
For this pair, Productive Robotics OB7 Stretch offers 4 kg over the stated 1250 mm reference, compared with 7 kg and 800 mm for Neuromeka Indy7 example. Productive Robotics OB7 Stretch has the larger stated distance by 450 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 3.2 kg: a 0.8 kg tool and adapter package carrying a 2.4 kg part or product group. This arithmetic leaves 3.8 kg below the Neuromeka Indy7 example’s nominal limit and 0.8 kg below Productive Robotics OB7 Stretch’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? Productive Robotics OB7 Stretch is the lower-or-equal nominal payload choice in this pair. Neuromeka Indy7 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. Neuromeka Indy7 provides a stated 800 mm reference, while Productive Robotics OB7 Stretch provides 1250 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 0.1 mm for Neuromeka Indy7 and ±0.1 mm for Productive Robotics OB7 Stretch. 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 Neuromeka Indy7 over Productive Robotics OB7 Stretch. Use a measured or validated application cycle before assigning a throughput benefit.
Programming, controls and production integration
Neuromeka Indy7 is paired here with the supplied model-specific control package, while Productive Robotics OB7 Stretch uses OB7 control computer with zero-programming teach tablet. 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
Arm prices: Neuromeka Indy7 is listed from €23,400 and Productive Robotics OB7 Stretch is listed from $25,000. Request configuration-specific quotations for Neuromeka Indy7 and Productive Robotics OB7 Stretch. 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 | Neuromeka Indy7 | Productive Robotics OB7 Stretch |
|---|---|---|
Strongest documented fit | seven-kilogram handling within the reviewed 800 mm maximum-load scope | seven-axis posture flexibility with 4 kg nominal capacity |
Main boundary | Do not pair the source review’s separate 1300 mm figure with the full 7 kg load. Confirm the delivered Indy generation, workspace and controller. | Confirm exact configuration, controller, wrist loading and installation envelope. |
Required approval | Exact Neuromeka 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 Neuromeka Indy7 when seven-kilogram handling within the reviewed 800 mm maximum-load scope solves the real constraint and its selected configuration passes the load and access checks. Advance Productive Robotics OB7 Stretch when seven-axis posture flexibility with 4 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
Neuromeka Indy7 has 6 arm axes and Productive Robotics OB7 Stretch 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 Neuromeka Indy7 vs Productive Robotics OB7 Stretch, 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?
Neuromeka Indy7 is the stronger starting point for seven-kilogram handling within the reviewed 800 mm maximum-load scope, while Productive Robotics OB7 Stretch is worth shortlisting for seven-axis posture flexibility with 4 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 7 kg for the specified Neuromeka Indy7 example and 4 kg for Productive Robotics OB7 Stretch, 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 Neuromeka Indy7 and 1250 mm for Productive Robotics OB7 Stretch 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 0.1 mm for Neuromeka Indy7 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 Neuromeka Indy7 and Productive Robotics OB7 Stretch 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 Neuromeka Indy7 and Productive Robotics OB7 Stretch. 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.
