{"id":"fanuc-sr-3ia-u","model_id":"SR-3iA/U","name":"FANUC SR-3iA/U","summary":"The FANUC SR-3iA/U is a 4-axis SCARA robot mounted upside down (ceiling mounted) for assembly, pick and place, inspection and packaging work. It carries a 3 kg payload at the wrist and has a 350 mm horizontal reach, moving through a full 360° envelope with no dead zones. It runs on FANUC R-30iB controllers and is programmed through the web-based iRProgrammer interface rather than a teach pendant.","study_notes":["Repeatability is quoted per axis: ±0.01 mm for J1 and J2, ±0.01 mm for J3, and ±0.004° for J4.","J3 is a linear axis with a 140 mm stroke and a maximum speed of 1500 mm/s.","J1 and J2 both have a motion range of ±225° and maximum speeds of 610 °/s and 840 °/s respectively.","J4 has a motion range of ±720° and a maximum speed of 3000 °/s.","Maximum push force is 150 N.","Allowable J4 moment/inertia is 0.06 kg·m².","I/O, 24 VDC, solenoid valves and air lines are integrated into the arm.","Programming uses the web-based iRProgrammer interface on a tablet or desktop computer; no iPendant Touch is needed.","Applications listed: assembly, dispensing and sealing, palletizing, picking and packaging.","Controller series is R-30iB Plus; the compatible controller listed is R-30iB Compact Plus."],"safety_notes":[],"sources":[{"url":"https://www.fanucamerica.com/products/robot/sr-3ia-u","title":"SR-3iA/U SCARA Robot","accessed":"2026-10-25"},{"url":"https://www.fanucamerica.com/uploads/files/data-sheets/sr-3ia-u-datasheet.pdf","title":"sr 3ia u datasheet","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"scara_robot","manufacturer":"fanuc","controllers":["fanuc-r-30ib-compact-plus","fanuc-r-30ib-plus"],"axes":4,"payload_kg":3,"reach_mm":350,"repeatability_mm":0.01,"weight_kg":27,"ip_rating":"IP20","joints":[{"name":"J1","range_min_deg":-225,"range_max_deg":225,"max_speed_deg_s":610},{"name":"J2","range_min_deg":-225,"range_max_deg":225,"max_speed_deg_s":840},{"name":"J3"},{"name":"J4","range_min_deg":-720,"range_max_deg":720,"max_speed_deg_s":3000}],"protocols":[],"standards":[],"variant_of":"fanuc-sr-3ia","error_codes":[]},"url":"https://machineschema.com/hardware/fanuc-sr-3ia-u","license":"https://creativecommons.org/licenses/by/4.0/"}
