Head to head
ABB IRB 6700 vs KUKA KR 120 R2700-2
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
ABB's flagship heavy six-axis family.
Workhorse heavy robot for general industrial handling
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the ABB IRB 6700 carries more, 150 kg to the KUKA KR 120 R2700-2's 120 kg. They run different controllers, the ABB IRB 6700 on the OmniCore / IRC5 and the KUKA KR 120 R2700-2 on the KR C4, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Both are aimed at material handling and machine tending, with the ABB IRB 6700 stretching to spot welding and the KUKA KR 120 R2700-2 to palletizing and press tending.
