Kuka KR 20-3

The industrial robot KR 20 is designed for light loads and is characterized by its versatility and flexibility in the application of several industrial sectors offering the required space, reach, load capacity, speed and energy consumption, it has an optimal accessibility to small spaces thanks to Its low level of interference contours and its wrist of fine design. Efficient for maximum accuracy and short cycle times. Floor mounting position.

KR C4 - Newest Kuka controller

More powerful, safer, more flexible, and above all more intelligent. The revolutionary concept of the KR C4 provides a firm foundation for the automation of tomorrow. It reduces costs in automation for integration, maintenance and servicing. The long-term efficiency and flexibility of the systems are increased at the same time. For this reason, KUKA has developed a new ground-breaking, clearly-structured system architecture that concentrates on open and powerful data standards. In this architecture, all integrated controllers – from SafetyControl, RobotControl, and MotionControl to LogicControl and ProcessControl – have a joint database and infrastructure which they use and share intelligently.
