Unable to load controller in quiz 5?

I changed chapters as well, the error seems to persist.


project_controller.tar is the package i have written

Hello @vasank1958,

You have some errors in your package, that’s why it’s not working. Specifically, you should have a look at the cpp and launch files. I’ve tried doing some modifications there and it worked correctly.

Also, it’s not necessary to change Units anymore. In case you want to restart the simulation to make sure that the plugin is loaded, you can just click on the following button (the lower one):

In case you cannot solve the issues, just let me know and I will send you the solutions to this Quiz.


hello sir , i tried skimming through the code by comparing with previous exercise , i am not able to find the error . can you give a clue like what syntax error i have made ?
