Cannot be load the simulation of "Unit 3 follow a line"

When I go to Unit 3, the simulation shows the default world (empty world). I can see turtlebot3 waffle, but nothing others.

Hi,

Your’re right! We will work on it to solve the web visualization issue.
BUT, I’ve checked and the cameras are rendering correctly, so it really doesnt affect a lot in your learning experience. The robot camera will get the correct data, have a look at rviz and you will see that its rendering correctly:

We will see into fixing this issue

I’ve just deployed a fix to make it visible again. Hope it works for you
