@mbaril the only other way that I know is to generate the URScript file offline and then you can serve that to the robot by sending it to port 30001, 30002 or 30003. If you look at the files on the robot by going to the terminal or doing this in URSim you will see that there are actually 3 fils generated when you use polyscope to generate a program, there is the .urp, .script and .txt files. The .urp is the polyscope program, the .txt is just s simple text representation of the poly scope program. The .script file is the actual program that will be executed on the robot.
I haven't done a lot of research or troubleshooting, but it seems that only URP files can be imported via a USB disk to the robot controller. Is there any way to import simple .txt files or do I absolutely have to use URSim to generate URP files? Thanks for helping!
