Execute secondary URScript command over ROS interface

Since R2023a


executeSecondaryURScriptCommand(ur,cmdStr) executes the secondary URScript command specified by cmdStr using ROS topic interface. This function accepts the URScript commands in terms of string or char. The command must be wrapped in a secondary program.


This function does not check for the syntax validity of the command. Ensure that you verify the command before sending it to the physical robot.


collapse all

Connect to a physical or simulated cobot, using either urROSNode or urROS2Node object (based on the option for connectivity – ROS or ROS 2, which you selected in the Hardware Setup screen).

  • Connect to a physical or simulated cobot at IP address on the ROS network.

    ur = urROSNode('');
  • Connect to a physical or simulated cobot on the ROS 2 network.

    ur = urROS2Node;

Specify the secondary URScript command to set standard digital output signal level, and execute the command.

commandString = "set_standard_digital_out(1,True)";
