KUKA LBR iiwa 14 R820

How LBR iiwa 14 R820 compares within +/- 5 kg payload.

Highest-spec cobot in the cohort. 7-axis arm with torque sensing in every joint. Research / precision-assembly focus. Premium-priced at $65-75K.

Why this cobot costs what it costs.

The LBR iiwa 14 is the most over-engineered cobot in this list, and that's load-bearing on the pricing. Seven axes with joint torque sensing throughout enables force-controlled assembly that no other arm in the cohort can match — automotive precision-assembly, medical device fitting, surgical robotics R&D. The $65-75K distributor band is well above the cohort average for the same 14 kg payload (UR10e at 12.5 kg is $45-60K), and the premium is paying for the sensor stack and the Sunrise.OS controller. Sunrise is Java-based and was specifically designed to let research labs and university programs write force-controlled motion at a level of granularity that production cobots don't expose. For most production cobot buyers, this is wildly excessive — UR10e or CRX-10iA does the same payload at 30-40% less cost. The KUKA iiwa makes sense when force-controlled assembly is the core task: snap-fit insertion, mating subassemblies with sub-mm tolerance, surgical applications. Anyone evaluating it for machine tending or palletizing is misreading the product.

Vendor-specific Bill of Materials.

These line items are what KUKA cells specifically need, beyond the bare arm. Multiply the arm price by 2.5-4x to land at typical installed cost — these items account for most of that multiplier.

Target buyer profile.

Research labs, university automation programs, precision-assembly cells where force feedback is the application-defining requirement. Not a first-cell purchase.

KUKA premium-priced. Single 2026 secondary source; iiwa 7 R800 variant typically 55-65K USD.
