Head to head
Comau Racer-5 vs KUKA KR 6 R900 (Agilus)
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Compact fast arm for assembly and light handling
Fast small robot for high-speed handling.
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the KUKA KR 6 R900 (Agilus) carries more, 6 kg to the Comau Racer-5's 5 kg. They run different controllers, the Comau Racer-5 on the R1C and the KUKA KR 6 R900 (Agilus) on the KR C4 compact, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Both are aimed at assembly and machine tending, with the Comau Racer-5 stretching to dispensing and packaging and the KUKA KR 6 R900 (Agilus) to material handling.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Comau Racer-5 when
- Low weight for flexible mounting orientations
- Fast cycle times for light-payload tasks
- Slim arm profile for tight fixtures
- Simple to relocate between cells
Watch for
- Low payload limits heavier tooling
- Short reach for large fixture layouts
Choose the KUKA KR 6 R900 (Agilus) when
- High speed
- Multiple mounting options
Watch for
- Low payload
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- Comau
- Controller
- R1C
- Class
- 6-axis industrial
Service, spares, and pendant training for the Comau Racer-5 run through Comau's R1C stack.
- Brand
- KUKA
- Controller
- KR C4 compact
- Class
- 6-axis industrial
Service, spares, and pendant training for the KUKA KR 6 R900 (Agilus) run through KUKA's KR C4 compact stack.
These arms run different controllers (R1C vs KR C4 compact). If your team already programs one of them, retraining programmers and stocking a second set of spares usually costs more than a small payload or reach advantage on paper.
Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | Comau Racer-5 | KUKA KR 6 R900 (Agilus) |
|---|---|---|
| Mounting | Floor, Ceiling, and Wall | Floor, Ceiling, and Wall |
| Robot mass | 32 kg | 52 kg |
| Protection (IP) | IP54 | IP54 |
Heavier arms want stiffer bases and more clearance around the swept volume, and they push freight and rigging costs up on the install. IP ratings only cover the section they name, so a wrist-only rating protects the wrist and nothing else; check the body rating separately before you commit the arm to a washdown or dusty cell.

Speed and cycle-time planning
Speed is rarely a single datasheet number across brands. Use payload, reach, and class as the planning frame, then confirm cycle time in a path study.
The Comau Racer-5 is a 6-axis industrial arm rated 5 kg at 809 mm with ±0.03 mm repeatability. The KUKA KR 6 R900 (Agilus) is a 6-axis industrial arm rated 6 kg at 901 mm with ±0.03 mm. Class changes how speed shows up in a cell: collaborative arms slow down near people and can speed up in a guarded mode, while industrial arms run at rated speed inside a fence or scanner field. Which arm cycles faster on your part depends on the path, the payload, and the safeguarding, so confirm the takt with a path study before you quote it.
Common questions
- Which has more payload, the Comau Racer-5 or the KUKA KR 6 R900 (Agilus)?
