Head to head
Mitsubishi MELFA ASSISTA vs Universal Robots UR3e
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Collaborative arm for shared assembly workspaces
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 Mitsubishi MELFA ASSISTA carries more, 5 kg to the Universal Robots UR3e's 3 kg, and the Mitsubishi MELFA ASSISTA reaches farther, 910 mm to 500 mm. They run different controllers, the Mitsubishi MELFA ASSISTA on the CR800-05VD 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 Mitsubishi MELFA ASSISTA lists Floor and Ceiling mounting while the Universal Robots UR3e lists Any orientation mounting, which the other does not. They target different work: the Mitsubishi MELFA ASSISTA at assembly and machine tending, the Universal Robots UR3e at collaborative assembly and small parts handling.
