Which robot is better for this application?

ABB IRB 6720 is the stronger starting point for 170 kg industrial handling within the documented 3100 mm working reference, while Kawasaki BX130X is worth shortlisting for 130 kg industrial handling within the documented 2991 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 170 kg for the specified ABB IRB 6720 170 kg / 3100 mm example and 130 kg for Kawasaki BX130X, 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 3100 mm for ABB IRB 6720 and 2991 mm for Kawasaki BX130X 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. The ABB family has distinct payload/reach combinations; this comparison uses ABB IRB 6720 170 kg / 3100 mm as a worked example. Match the order code, repeatability and protection package before purchasing. 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 ±0.06 mm for ABB IRB 6720 scope and ±0.06 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 ABB IRB 6720 and Kawasaki BX130X 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 ABB IRB 6720 and Kawasaki BX130X. 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.
