FANUC R-2000iC/165F

The R-2000iC/165F is the arm you see lined up by the dozen in an automotive body shop. It puts 165 kg at the wrist and reaches 2655 mm, the envelope you need to swing a spot-welding gun around a car body. Repeatability holds ±0.05 mm, which for a 1,090 kg machine on this reach is why shops buy FANUC's heavy line.

At 1,090 kg this is a floor-anchored or inverted install, not a robot you reposition casually. Its trade-offs follow from that size: it needs real safeguarding and a footprint to match. It ships on the R-30iB Plus controller, and like the rest of the R-2000 family it is common enough that parts and integrator familiarity come easy.

Being a mainstream FANUC platform, it shares the same service routines as the smaller arms. Payload and load estimation matters more here, since running a heavy weld gun near the 165 kg limit is the case that setup was written for. Six-point TCP calibration keeps the gun tip accurate, and a full image backup protects the cell before controller work.

A machine this size leans on big spares in the parts catalog: J1 servo motor and J2 servo motor units, cycloidal reducer gearsets, and the cable dress pack that carries weld cable along the arm. Servo alarms like SRVO-050 and SRVO-021 are documented in the fault-code reference with their recovery steps.

If you're benchmarking the heavy class, the natural comparisons are the KUKA KR 210 R2700, ABB IRB 6700, and Yaskawa GP180, all sized for the same body-shop and heavy-handling work.
