Head to head
FANUC LR Mate 200iD/4S vs Omron i4
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Compact short-arm robot for dense benchtop cells
Compact SCARA for light assembly and packaging
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The FANUC LR Mate 200iD/4S is a 6-axis industrial arm and the Omron i4 is a SCARA arm, so this comes down to which job you are building the cell around rather than a spec-for-spec race. They run different controllers, the FANUC LR Mate 200iD/4S on the R-30iB Plus and the Omron i4 on the Built-in internal controller, so whichever platform your team already programs and stocks parts for is a real tiebreaker. For a tight or overhead cell, the FANUC LR Mate 200iD/4S lists Floor and Inverted mounting while the Omron i4 lists Table and Wall mounting, which the other does not. Both are aimed at assembly and dispensing, with the FANUC LR Mate 200iD/4S stretching to machine tending.
