Head to head
Comau AURA vs KUKA KR 120 R2700-2
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Heavy payload robot that can run in collaborative mode
Workhorse heavy robot for general industrial handling
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The first question here is not specs but the cell: the Comau AURA is a collaborative arm designed for reduced-speed operation near people (fenceless only where an application risk assessment allows it), while the KUKA KR 120 R2700-2 is a 6-axis industrial arm that runs behind a guard at full speed. Both are aimed at material handling and machine tending, with the Comau AURA stretching to collaborative assembly and the KUKA KR 120 R2700-2 to palletizing and press tending.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Comau AURA when
- Industrial payload with collaborative capable sensing
- Long reach for heavy component handling
- Can switch between guarded and collaborative operation
- Rugged construction for continuous industrial duty
Watch for
- Still requires a risk assessment for fence free use at this size
- Large footprint and mass need foundation planning
Choose the KUKA KR 120 R2700-2 when
- Well proven QUANTEC platform
- Flexible mounting including ceiling
- Strong payload to footprint ratio
- Broad tooling and integration support
Watch for
- Large swing radius needs cell space planning
- Heavier tooling reduces effective payload margin

Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | Comau AURA | KUKA KR 120 R2700-2 |
|---|---|---|
| Mounting | Floor | Floor |
| Robot mass | 1,615 kg | 1,069 kg |
| Protection (IP) | Not confirmed | IP65 body / IP65 or IP67 in-line wrist |
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.
Application fit

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 AURA is a collaborative arm rated 170 kg at 2790 mm with ±0.1 mm repeatability. The KUKA KR 120 R2700-2 is a 6-axis industrial arm rated 120 kg at 2701 mm with ±0.05 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 AURA or the KUKA KR 120 R2700-2?
- The Comau AURA has more payload at 170 kg versus 120 kg.
- Which reaches farther?
- The Comau AURA has more reach at 2790 mm versus 2701 mm.
- Which is more precise?
- The KUKA KR 120 R2700-2 holds tighter repeatability at ±0.05 mm.
- Should I choose the Comau AURA or the KUKA KR 120 R2700-2?
- Match the pick to the job. The Comau AURA is a collaborative arm at 170 kg and 2790 mm. The KUKA KR 120 R2700-2 is a 6-axis industrial arm at 120 kg and 2701 mm.
- Do the Comau AURA and KUKA KR 120 R2700-2 use the same controller?
- No. The Comau AURA uses an unconfirmed controller and the KUKA KR 120 R2700-2 uses KR C4.
- How do the IP ratings compare?
- The Comau AURA is rated not confirmed. The KUKA KR 120 R2700-2 is rated IP65 body / IP65 or IP67 in-line wrist. Check wrist versus body coverage before washdown or dusty cells.
