KR CYBERTECH ARC nano is a series of compact and lightweight robots that provide a high performance with a level of minimum interference contours, allow access to difficult areas; has a 50mm hollow wrist that allows reduced movement of the main shaft with very short cycle times; this robot is characterized by its high precision and accuracy at high speeds for greater profitability with minimum costs. is in three different variants with mounting positions in angle, wall, floor, ceiling.

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.
