KUKA linear units are implemented as an external robot axis, which means that no additional controller is needed.

		KL 250-2 KUKA linear units are translational motion units. They can be used to extend a robot’s work envelope or alternatively to move workpieces or tools within the work envelopes of a number of robots. ...more
