Cant launch the Turtle Bot (kobuki) Simulation with the wall for the quiz 1 in the ROS Basics In 5 Days

Hello Guys,

I am a Robotics Hardware Engineer, very new to ROS. For the unit 4 quiz, I am unable to start the simulation with the wall. When I launch a new simulation by selecting Turtlebot3 in an empty world environment, I don’t get a wall. Did anyone face a similar issue?


Hi Harnav,

The simulations in the courses should start automatically, so there would be no reason to launch a new one unless I’m missing something for that particular quiz.

Can you try reloading and seeing if the simulation starts by itself?

Can you send some screenshots so I can understand your issue better?
