Head to head
Comau NJ-165 vs Yaskawa Motoman GP88
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Heavy duty robot for handling and press tending
Heavier duty robot for demanding handling tasks
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the Comau NJ-165 carries more, 165 kg to the Yaskawa Motoman GP88's 88 kg, and the Comau NJ-165 reaches farther, 3000 mm to 2236 mm. If precision drives the job, the Yaskawa Motoman GP88 holds the tighter repeatability at ±0.03 mm. They run different controllers, the Comau NJ-165 on the C5G and the Yaskawa Motoman GP88 on the YRC1000, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the Comau NJ-165 lists Floor and Ceiling, and the Yaskawa Motoman GP88 lists Floor, Wall, Ceiling, and Tilt.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Comau NJ-165 when
- High payload for large part transfer
- Stiff arm holds accuracy under heavy load
- Proven in press tending and foundry lines
- Broad tooling compatibility
Watch for
- Large footprint and mass need dedicated foundation work
- Not suited to light or high speed tasks
Choose the Yaskawa Motoman GP88 when
- Strong payload margin for multi part grippers
- Solid reach for servicing wide cells
- IP67 wrist standard; optional higher body protection on applicable versions
- Good repeatability for its payload class
Watch for
- Large mass and footprint; confirm floor, wall, ceiling, or tilt mounting against the cell layout
- Larger footprint than lighter GP models
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- Comau
- Controller
- C5G
- Class
- 6-axis industrial
Service, spares, and pendant training for the Comau NJ-165 run through Comau's C5G stack.
- Brand
- Yaskawa
- Controller
- YRC1000
- Class
- 6-axis industrial
Service, spares, and pendant training for the Yaskawa Motoman GP88 run through Yaskawa's YRC1000 stack.
These arms run different controllers (C5G 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 | Comau NJ-165 | Yaskawa Motoman GP88 |
|---|---|---|
| Mounting | Floor and Ceiling | Floor, Wall, Ceiling, and Tilt |
| Robot mass | 1,240 kg | 630 kg |
| Protection (IP) | IP65 / IP67 | IP67 wrist / IP54 body |
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 material handling, press tending, palletizing, 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 Comau NJ-165 is a 6-axis industrial arm rated 165 kg at 3000 mm with ±0.09 mm repeatability. The Yaskawa Motoman GP88 is a 6-axis industrial arm rated 88 kg at 2236 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 NJ-165 or the Yaskawa Motoman GP88?
