Head to head
KUKA KR 3 AGILUS vs Universal Robots UR3e
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Compact high speed arm for small parts 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 first question here is not specs but the cell: the Universal Robots UR3e is a collaborative arm designed for reduced-speed operation near people (fenceless only where an application risk assessment allows it), while the KUKA KR 3 AGILUS is a 6-axis industrial arm that runs behind a guard at full speed. They run different controllers, the KUKA KR 3 AGILUS on the KR C4 compact 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. For a tight or overhead cell, the KUKA KR 3 AGILUS lists Floor and Ceiling mounting while the Universal Robots UR3e lists Any orientation mounting, which the other does not. Both are aimed at small parts handling and pick and place, with the KUKA KR 3 AGILUS stretching to assembly and dispensing and the Universal Robots UR3e to collaborative assembly.
- Very fast cycle times for light payloads
- Small footprint fits crowded cells
- Multiple mounting orientations
- Low integration cost
- Very compact for tight benchtop cells
- Fast setup with polyscope programming
- Any orientation mounting
- Low integration cost for light tasks
