To clarify, the difference between "run and robot" and "generate program" is that that when using "run on robot", robodk sends commands to the robot directly as the program is simulated in robodk but generally can't be easily modified by the user. "Generate program" generates a script using python that the robot executes. Since the dobot does not have a native scripting language the robodk post processor generates a python script that sends commands to the dobot. Generating the Program and Sending it simply automatically runs that script after it's generated.

The post processor is a python script so that you can add new functions to it like unique tools. The problem with you seem to having with running the script is that you don't have the python module "packaging" installed. You install python modules from the command line using a command like "pip install packaging"
