ABB GoFa CRB 15000 vs KUKA LBR iiwa 14

ABB GoFa CRB 15000

ABB GoFa CRB 15000 is ABB's mid-range single-arm collaborative robot — a 5 kg payload, 950mm reach cobot positioning ABB competitively against the Universal Robots UR5e. GoFa is ABB's fastest cobot, with speeds up to 2.2 m/s enabling higher throughput than most competing cobots at this payload class. Integrated force control across all six joints enables precise assembly, polishing, and path-following applications without external force sensors. IP54-rated for protection against dust and coolant splash. GoFa is designed for machine tending, assembly, quality inspection, and surface treatment applications where speed matters.

KUKA LBR iiwa 14

KUKA LBR iiwa 14 is the most sophisticated collaborative robot available — the first industrial robot with joint torque sensing on all seven axes, enabling it to feel and respond to contact forces with human-level sensitivity. Developed from KUKA's DLR research heritage, the iiwa's 7-DOF configuration gives it the same kinematic redundancy as a human arm, enabling it to navigate around obstacles and reach into confined spaces. At 14 kg payload, it handles heavier collaborative tasks than most cobots. The iiwa is the reference platform for sensitive assembly, medical robotics, and aerospace applications requiring compliant motion. Its torque sensing enables compliant insertion tasks — pressing parts together with controlled force — that rigid cobots cannot safely perform.
