FANUC M-410iC/185 vs ABB IRB 6750S: Heavy Robot Comparison
The FANUC M-410iC/185 and the ABB IRB 6750S sit in the same payload range but do very different jobs. The M-410iC/185 is a four-axis floor palletizer and costs about a fifth less. The IRB 6750S is a six-axis shelf-mounted robot that works downward into machines, with 185 to 350 kg and up to 3900 mm reach.
Quick verdict. The FANUC M-410iC/185 is the better choice for palletizing, with 3143 mm reach and a listed price $20,000 lower. The ABB IRB 6750S is the better choice for tending die casting, injection moulding and presses from a raised shelf, with up to 350 kg and 3900 mm.
M-410iC/185 and IRB 6750S at a glance
The FANUC M-410iC/185 carries 185 kg over 3143 mm, repeats to ±0.05 mm and runs on the R-30iB Plus (A- or B-cabinet) controller. It weighs 1600 kg on the pedestal base, controller included.
The ABB IRB 6750S carries 185 to 350 kg over 3200 to 3900 mm, mounts on a shelf above floor level and runs on OmniCore.

Shelf mounting against floor palletizing
The IRB 6750S is installed above floor level on a shelf or raised frame and works downward into machines, which keeps the floor around presses and moulding machines clear. The M-410iC/185 stands on the floor and uses four axes to keep its gripper level for stacking.
Payload and reach
ABB offers the IRB 6750S as 350 kg / 3200 mm, 270 kg / 3600 mm and 215 kg / 3900 mm, with LeanID versions from 185 to 270 kg. All reach further than the 3143 mm of the M-410iC/185, and most carry more than its 185 kg.
Applications and precision
ABB designs the IRB 6750S for material handling, die casting, injection moulding and spot welding. The M-410iC/185 is a dedicated palletizer for cases, bags and layers. FANUC publishes ±0.05 mm repeatability; the IRB 6750S review lists no repeatability figure.
