Head to head
KUKA KR 6 R900 (Agilus) vs Yaskawa Motoman GP8
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Fast small robot for high-speed handling.
Nimble 8 kg arm with a fast wrist.
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the Yaskawa Motoman GP8 carries more, 8 kg to the KUKA KR 6 R900 (Agilus)'s 6 kg. If precision drives the job, the Yaskawa Motoman GP8 holds the tighter repeatability at ±0.01 mm. They run different controllers, the KUKA KR 6 R900 (Agilus) on the KR C4 compact and the Yaskawa Motoman GP8 on the YRC1000, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the KUKA KR 6 R900 (Agilus) lists Floor, Ceiling, and Wall, and the Yaskawa Motoman GP8 lists Floor, Wall, Tilt, and Ceiling.
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 6 R900 (Agilus) when
- High speed
- Multiple mounting options
Watch for
- Low payload
Choose the Yaskawa Motoman GP8 when
- Fast
- Flexible mounting
Watch for
- Low payload
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.

Service, spares, and pendant training for the Yaskawa Motoman GP8 run through Yaskawa's YRC1000 stack.
These arms run different controllers (KR C4 compact 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 6 R900 (Agilus) | Yaskawa Motoman GP8 |
|---|---|---|
| Mounting | Floor, Ceiling, and Wall | Floor, Wall, Tilt, and Ceiling |
| Robot mass | 52 kg | 32 kg |
| Protection (IP) | IP54 | IP67 |
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
Where each arm is aimed, based on the applications listed on its robot page.
Both pages list assembly, material handling, and machine tending.

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 6 R900 (Agilus) is a 6-axis industrial arm rated 6 kg at 901 mm with ±0.03 mm repeatability. The Yaskawa Motoman GP8 is a 6-axis industrial arm rated 8 kg at 727 mm with ±0.01 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
