Head to head
Kawasaki duAro vs Universal Robots UR3e
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Dual arm SCARA style cobot for tabletop assembly
Small tabletop cobot for light assembly tasks
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the Universal Robots UR3e carries more, 3 kg to the Kawasaki duAro's 2 kg, and the Kawasaki duAro reaches farther, 760 mm to 500 mm. If precision drives the job, the Universal Robots UR3e holds the tighter repeatability at ±0.03 mm. They run different controllers, the Kawasaki duAro on the F61 and the Universal Robots UR3e on the e-Series Control Box, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the Kawasaki duAro lists Floor, and the Universal Robots UR3e lists Any orientation. Both are aimed at collaborative assembly and small parts handling, with the Kawasaki duAro stretching to kitting and the Universal Robots UR3e to pick and place.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Kawasaki duAro when
- Dual arm layout mimics a human work station
- Low profile base fits tabletop lines
- Collaborative operation for many light tasks
- Simple direct teaching programming
Watch for
- Limited payload per arm
- Horizontal SCARA style motion is not suited to all part geometries
Choose the Universal Robots UR3e when
- Very compact for tight benchtop cells
- Fast setup with polyscope programming
- Any orientation mounting
- Low integration cost for light tasks
Watch for
- Light payload limits it to small parts
- Short reach compared to larger UR models
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- Kawasaki
- Controller
- F61
- Class
- collaborative
Service, spares, and pendant training for the Kawasaki duAro run through Kawasaki's F61 stack.
- Brand
- Universal Robots
- Controller
- e-Series Control Box
- Class
- collaborative
Service, spares, and pendant training for the Universal Robots UR3e run through Universal Robots's e-Series Control Box stack.
These arms run different controllers (F61 vs e-Series Control Box). 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 | Kawasaki duAro | Universal Robots UR3e |
|---|---|---|
| Mounting | Floor | Any orientation |
| Robot mass | 207 kg | 11.2 kg |
| Protection (IP) | Not confirmed | 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.
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 Kawasaki duAro is a collaborative arm rated 2 kg at 760 mm with ±0.05 mm repeatability. The Universal Robots UR3e is a collaborative arm rated 3 kg at 500 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
