Connect to the robot

Connect to a UR robot

After creating an instance UR of your cobot, you need to call the Connect method to initiate communication with the robot.

This method takes as parameter a ConnectParameters object which describes the functionalities to be activated and the parameters of each feature.

The Connect() method can throw a InvalidLicenseException if your trial period is over or if your license key is invalid.

Please refer to the specific page for each protocol to understand the parameters.
