Head to head
Universal Robots UR3e vs Universal Robots UR5e
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Small tabletop cobot for light assembly tasks
The cobot that defined the category.
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the Universal Robots UR5e carries more, 5 kg to the Universal Robots UR3e's 3 kg, and the Universal Robots UR5e reaches farther, 850 mm to 500 mm. They run different controllers, the Universal Robots UR3e on the e-Series Control Box and the Universal Robots UR5e on the PolyScope, so whichever platform your team already programs and stocks parts for is a real tiebreaker. For a tight or overhead cell, the Universal Robots UR3e lists Any orientation mounting while the Universal Robots UR5e lists Any mounting, which the other does not. They target different work: the Universal Robots UR3e at collaborative assembly and small parts handling, the Universal Robots UR5e at assembly and machine tending.
- Very compact for tight benchtop cells
- Fast setup with polyscope programming
- Any orientation mounting
- Low integration cost for light tasks
- Huge ecosystem of UR+ end-effectors
- Easy to program
- Built-in force sensing
