The verdict

The specs separate them here: the Epson SCARA T6 carries more, 6 kg to the Omron i4's 5 kg. If precision drives the job, the Omron i4 holds the tighter repeatability at ±0.01 mm. They run different controllers, the Epson SCARA T6 on the Built-in 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 Epson SCARA T6 lists Tabletop mounting while the Omron i4 lists Table and Wall mounting, which the other does not. Both are aimed at assembly and packaging, with the Epson SCARA T6 stretching to machine tending.

Epson SCARA T6
  • Competitive cost for a full-size SCARA
  • Fast planar cycle times
  • Straightforward setup with Epson RC+ software
  • Multiple reach variants available
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
