URDF Course: Bug with Unit 4 Quiz


I am taking the Unit4 Quiz of URDF. After evaluation, the system stated that it can not find my control topics and gave me 7 points. However, when I check using rostopic list, every topic is available as required.

Can you please suggest me a way to get over this. I only have 1 attempt left.

Thank you in advance.

Thank you, I gonna check it out and let you know the result ASAP

Hi duckfrost, thank you for giving me the solution. However, even with your solution, I still scored 7. That was my last attempt, and I really don’t know what was wrong
