Head to head
KUKA KR 300 R2500 vs Yaskawa Motoman GP280
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
High payload robot for heavy parts and tooling
High payload robot for the heaviest handling jobs
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
On paper these two are close, 300 kg against 280 kg and 2496 mm against 2446 mm of reach, near enough that the spec sheet alone will not decide it. They run different controllers, the KUKA KR 300 R2500 on the KR C4 and the Yaskawa Motoman GP280 on the YRC1000, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the KUKA KR 300 R2500 lists Floor and Ceiling, and the Yaskawa Motoman GP280 lists Floor. Both are aimed at palletizing and material handling, with the KUKA KR 300 R2500 stretching to machine tending.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the KUKA KR 300 R2500 when
- High payload with a manageable footprint
- Rigid arm structure for heavy tooling
- Good repeatability given its load class
- Established support network
Watch for
- Requires a reinforced foundation
- Cycle times drop as payload approaches rated maximum
Choose the Yaskawa Motoman GP280 when
- High payload for heavy component handling
- Reach suited to large pallet footprints
- Durable construction for continuous duty
- Consistent accuracy under heavy load
Watch for
- Large footprint and mass need foundation planning
- Overkill for light or medium duty tasks
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- KUKA
- Controller
- KR C4

Service, spares, and pendant training for the KUKA KR 300 R2500 run through KUKA's KR C4 stack.
- Brand

Service, spares, and pendant training for the Yaskawa Motoman GP280 run through Yaskawa's YRC1000 stack.
These arms run different controllers (KR C4 vs YRC1000). 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 | KUKA KR 300 R2500 | Yaskawa Motoman GP280 |
|---|---|---|
| Mounting | Floor and Ceiling | Floor |
| Robot mass | 1,120 kg | 1,300 kg |
| Protection (IP) | IP65 (robot & in-line wrist); IP67 foundry in-line wrist | IP67 wrist / IP54 body (IP65 body with XP option) |
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 KUKA KR 300 R2500 is a 6-axis industrial arm rated 300 kg at 2496 mm with ±0.06 mm repeatability. The Yaskawa Motoman GP280 is a 6-axis industrial arm rated 280 kg at 2446 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 KUKA KR 300 R2500 or the Yaskawa Motoman GP280?
- The KUKA KR 300 R2500 has more payload at 300 kg versus 280 kg.

- The KUKA KR 300 R2500 has more reach at 2496 mm versus 2446 mm.
- Which is more precise?
- The Yaskawa Motoman GP280 holds tighter repeatability at ±0.05 mm.
- Should I choose the KUKA KR 300 R2500 or the Yaskawa Motoman GP280?
- Match the pick to the job. The KUKA KR 300 R2500 is a 6-axis industrial arm at 300 kg and 2496 mm. The Yaskawa Motoman GP280 is a 6-axis industrial arm at 280 kg and 2446 mm.
- Do the KUKA KR 300 R2500 and Yaskawa Motoman GP280 use the same controller?
- No. The KUKA KR 300 R2500 uses KR C4 and the Yaskawa Motoman GP280 uses YRC1000.
- How do the IP ratings compare?
- The KUKA KR 300 R2500 is rated IP65 (robot & in-line wrist); IP67 foundry in-line wrist. The Yaskawa Motoman GP280 is rated IP67 wrist / IP54 body (IP65 body with XP option). Check wrist versus body coverage before washdown or dusty cells.
