KUKA: LBR iiwa – a new era of sensitive robotics

“For years, companies and development engineers around the world have dreamt of a robot that is suitable for industrial applications and feel. KUKA has made this dream come true. A quantum leap!” - Prof. Bruno Siciliano, Professor of Robotics at the University of Naples, Italy.

The KUKA LBR iiwa is the first sensitive lightweight robot suitable for use in the industrial applications. It enables automation in areas where it was previously impossible or not economically viable. “LBR” stands for “Leichtbauroboter” (German for lightweight robot), “iiwa” for “intelligent industrial work assistant”.

Why is the LBR iiwa so sensitive?

Its joint torque sensors in all seven axes sense every torque acting on them. These signals each the controller of the LBR iiwa within milliseconds and can be taken into consideration accordingly, e.g. to allow the robot to retract on making contact.

What makes the LBR iiwa so agile?

The LBR iiwa has a redundant kinematic system with seven axes. This means that there is always more than one way of reaching a destination. Particularly in the case of relatively inaccessible installation situations, the LBR iiwa can move its axes to an advantageous position without the need for complicated motion of the workplace.

How precisely does the LBR iiwa work?

The LBR iiwa has a repeatability of +/- 0.1 mm. It also has very high path accuracy. This is because its joint sensors enable it to optimise its motion within milliseconds, for example when maintaining contact with a workpiece while moving over it.

Pioneering control technology

The basis for the innovative LBR iiwa robotics consists of the specially developed KUKA Sunrise control technology, the KUKA Sunrise Cabinet control hardware and the KUKA Sunrise OS control software. Kuka Sunrise Cabinet unites safety control, robot control, logic control and process control of the entire system. Its interfaces, scalability, performance and openness mean that there are virtually limitless automation possibilities. In the future, it will also be possible to control multiple lightweight robots with a single controller
