KAREL & User Socket Messaging

In this video, Software Product Manager Eric Lattas provides background on the powerful, customizable technique of using KAREL and User Socket Messaging (USM) for external motion control in industrial robots. He explains how KAREL leverages USM built-ins to establish a robust TCP/IP socket connection over Ethernet with a PC application. This connection allows the external controller to send real-time positional data, which the KAREL program feeds into a robot position register for execution by a Teach Pendant program. Eric notes that the user-defined protocol offers maximum flexibility to customize motion parameters, making it an ideal solution for complex applications and viable on both current and older FANUC controllers with an Ethernet interface.
