ABB IRB 6700 wins for volume deployment, FANUC for extreme payload
The ABB IRB 6700 is the world's best-selling heavy industrial robot for good reason — 250,000+ units deployed across welding, handling, and machining at 235kg payload. Its combination of RobotStudio simulation, ABB Ability cloud analytics, and OPC-UA connectivity gives it an edge in integrated digital factory deployments. FANUC's M-2000iA/2300 wins only on payload — 2,300kg vs. 235kg — which is decisive when you need to move complete car bodies or very heavy castings, but overkill for most industrial applications.
IRB 6700 is better for
high-volume automotive welding, material handling and buyers wanting the deepest global support network
M-2000iA/2300 is better for
ultra-heavy payload applications above 500kg where FANUC's world-record capacity is the only option
