ABB IRB 1100

The ABB IRB 1100 is a compact 6-axis industrial arm carrying a 4 kg payload over a 580 mm reach. Its 0.01 mm repeatability is the figure that defines the work, aiming it at assembly where a steady tool-center-point counts for more than a wide work-envelope. The arm weighs 21 kg, light enough for the benchtop cells it is built to fit.

The mounting field lists any angle, so integrators can tilt or invert the base to match how a fixture presents parts. That freedom helps when the arm shares a tight station with part feeders and cameras. ABB OmniCore controller hardware runs it.

The record carries an IP40 standard / IP67 option rating. Its jobs reach past assembly into dispensing, machine-tending, and packaging. Each of those leans on the same precise, repeatable positioning that small-parts work demands.

In dispensing, the arm traces a consistent bead along a taught path, and the 0.01 mm repeatability keeps that line even. For machine-tending, the 580 mm reach keeps the loading zone compact and limits how far fixtures can spread. The record positions the arm as fast for short-cycle tasks, which fits light packaging duty.

The 4 kg payload rules out heavier grippers, so end-of-arm tooling has to stay light and simple. That limit and the short reach are the tradeoffs buyers take for the precision and the small footprint. SafeMove options extend the arm into shared workspaces for close human interaction.
