Key features

Highest performance

Class-leading position repeatability of 0.03mm, with outstanding cycle time thanks to OmniCore™ motion control

Energy savings

Up to 20% less energy consumption[1] thanks to a lean design that is up to 10% lighter[2], plus OmniCore™ power saving

Greater choice

Modular design enables 22 powerful variants to meet different customer needs

Designed to last

11 of the robot variants are equipped with a LeanID DressPack that eliminates swinging cables and supports off-line programming


Wide range for greater choice

These large robots are based on the same groundbreaking modular design, with standardized components across all large robot platforms, including the base, lower arm, and upper arm. All of the robots now have the same footprint, enabling faster, more convenient, and more flexible installation when changing robots in different production lines.

Consumes up to 20% less energy

Helping customers operate more sustainably, these large robots consume up to 20%1 less energy. This was achieved by the robot’s lean design, up to 10% lighter2 and the OmniCore™ controller’s revolutionary, energy-saving power grid feedback solution.

Unprecedented performance thanks to OmniCoreTM

These large robots are powered by the OmniCoreTM controller and RobotWare, providing best-in-class motion control enabled by ABB’s TrueMove for increased accuracy, QuickMove for high speed, and SafeMove for safe collaboration. The highest level of performance is achieved through numerous performance enhancements, including class-leading pose repeatability of 0.03 mm, and path repeatability of 0.08mm, and outstanding cycle time, and stiffness. These improvements increase productivity by enabling more products to be manufactured in less time. 

The ability to withstand harsh applications

Built to operate in the harshest environments — available with Foundry Plus protection


Ideal for a wide range of applications, including material handling, high-precision assembly, spot welding, laser welding, dispensing & gluing, and machine tending. In the automotive sector, these robots can support EV battery production of varying sizes (individual cells, modules and complete packages), high-precision car body assembly, as well as spot welding and the ability to enter tight spaces inside a vehicle to install dashboards or seats.
