KUKA KR 6 R700-2 vs Shibaura Machine TVL700: Robot Comparison

IN A NUTSHELL

KUKA KR 6 R700-2 vs Shibaura Machine TVL700 is a choice about assembly and machine tending. KUKA KR 6 R700-2 and Shibaura Machine TVL700 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.

KUKA KR 6 R700-2 vs Shibaura Machine TVL700: quick verdict

Shortlist KUKA KR 6 R700-2 for 6 kg industrial handling within the documented 726 mm working reference. Shortlist Shibaura Machine TVL700 for 4 kg industrial handling within the documented 801 mm working reference. 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 KUKA KR 6 R700-2 against Shibaura Machine TVL700. 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.

KUKA KR 6 R700-2: design and configuration

The KUKA KR 6 R700-2 is assessed here at the reviewed 6 kg payload and 726 mm working reference, with 6 arm axes, ±0.02 mm repeatability and the KR C5 micro controller scope. The AGILUS configuration must be matched to its exact arm length, rated/maximum load and controller package. Include the full tool mass and cable arrangement, then validate inner workspace, joint limits and the complete approach. A catalogue maximum load does not establish maximum acceleration with an arbitrary offset or wrist inertia.

Shibaura Machine TVL700: design and configuration

Shibaura Machine TVL700 is compared using the TVL700 reference with 4 kg maximum load, 801 mm flange reach and ±0.03 mm repeatability. The general maximum load is 4 kg; a separate downward configuration permits 5 kg. The calculations retain 4 kg. Its 700 mm arm length is distinct from the 801 mm flange reach. The manufacturer separately specifies a 1 kg rated load and the matched TSL3100 / TSL3100E controller. Six axes support tool attitude control that a SCARA wrist cannot provide, but they add joint-limit, singularity and recovery-path checks. Validate complete gripper mass, wrist moments, inertia and base reactions. The maximum-load reference used for arithmetic is not approval of an offset payload or continuous high-acceleration operation. Repeatability is specified for one-direction motion under stable thermal conditions; it is not absolute accuracy or guaranteed trajectory error. Standard-cycle demonstrations do not establish the loaded cycle time of another application. Specify cable routing, pneumatic services and any IP option in the quotation rather than assuming the family illustration includes them.

For this pair, Shibaura Machine TVL700 offers 4 kg over the stated 801 mm reference, compared with 6 kg and 726 mm for KUKA KR 6 R700-2 example. Shibaura Machine TVL700 has the larger stated distance by 75 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 2.8 kg below the KUKA KR 6 R700-2 example’s nominal limit and 0.8 kg below Shibaura Machine TVL700’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? Shibaura Machine TVL700 is the lower-or-equal nominal payload choice in this pair. KUKA KR 6 R700-2 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. KUKA KR 6 R700-2 provides a stated 726 mm reference, while Shibaura Machine TVL700 provides 801 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 KUKA KR 6 R700-2 and ±0.03 mm for Shibaura Machine TVL700. 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 KUKA KR 6 R700-2 over Shibaura Machine TVL700. Use a measured or validated application cycle before assigning a throughput benefit.

Programming, controls and production integration

KUKA KR 6 R700-2 is paired here with KR C5 micro, while Shibaura Machine TVL700 uses TSL3100 / TSL3100E. 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. These robot systems require task-specific safeguarding; payload or compact size does not establish safe unguarded operation. 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: KUKA KR 6 R700-2 is listed from $26,500. Request configuration-specific quotations for KUKA KR 6 R700-2 and Shibaura Machine TVL700. 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 KUKA KR 6 R700-2 when 6 kg industrial handling within the documented 726 mm working reference solves the real constraint and its selected configuration passes the load and access checks. Advance Shibaura Machine TVL700 when 4 kg industrial handling within the documented 801 mm working reference 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

KUKA KR 6 R700-2 has 6 arm axes and Shibaura Machine TVL700 has 6 arm axes. Both have six arm axes; equal axis counts do not establish equal joint travel, inner workspace or fixture access. Compare tool detection, sensing, machine I/O and recovery as separate delivered functions.

Industries and application fit

For KUKA KR 6 R700-2 vs Shibaura Machine TVL700, 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?

KUKA KR 6 R700-2 is the stronger starting point for 6 kg industrial handling within the documented 726 mm working reference, while Shibaura Machine TVL700 is worth shortlisting for 4 kg industrial handling within the documented 801 mm working reference. 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 6 kg for the specified KUKA KR 6 R700-2 example and 4 kg for Shibaura Machine TVL700, 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 726 mm for KUKA KR 6 R700-2 and 801 mm for Shibaura Machine TVL700 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 KUKA KR 6 R700-2 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.

How should purchase prices be compared?

Use current written quotations for KUKA KR 6 R700-2 and Shibaura Machine TVL700 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 KUKA KR 6 R700-2 and Shibaura Machine TVL700. 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.
