The verdict

The specs separate them here: the FANUC SR-6iA carries more, 6 kg to the Omron i4's 5 kg. They run different controllers, the FANUC SR-6iA on the R-30iB Compact 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 SR-6iA lists Floor mounting while the Omron i4 lists Table mounting, which the other does not. Both are aimed at assembly and packaging, with the FANUC SR-6iA stretching to machine tending.

FANUC SR-6iA
  • High-speed planar motion for pick-and-place
  • Tight repeatability for small parts assembly
  • Compact footprint for dense cell layouts
  • Shares programming with FANUC six-axis lines
Omron i4
  • Very compact for dense bench cells
  • Tight repeatability for small-parts assembly
  • Integrates with Omron vision and PLC systems
  • Low mass simplifies mounting
