Error details
Gazebo should be showing a maze as indicated on the left.
Hi @professor.herman, sometimes Gazebo doesn’t behave correctly. I checked and it loaded correctly the maze, so I recommend you to restart your simulation by clicking the left button on the top of the simulation window. Then it should load correctly, let us know if that solved the issue!
Tried that a number of times already. Quit and restarted the course. Restarted the pc. No effect.
In addition, based on my bot’s behavior it appears to see walls and react to them that I can’t see.
Now Gazebo won’t load and I’ve got 77Mbps download and 15 up.
Update. I downloaded a new version of the program and I can now see the maze in black but not the brown “wood” as shown in the tutorial. However I am still unable to proceed to the next level.
That’s good to know, regarding the black maze it is because Gazebo is loading the meshes, first start with the maze black and then you will see the wooden texture.
Can you select the units if you click on “6 - Project …”? There you can select the next or previous unit.
The only place I can see where something should be “clickable” is on the bottom left of the screenshot I sent (see above). The left arrow is “clickable” but not the right arrow, ie. I can’t progress to the next section even though I’ve selected the green box.
I downloaded a new version of the program and I can now see the maze in black but not the brown “wood” as shown in the tutorial.
It looks like something is blocking the simulation on your browser, internet connection or PC, because it loads fine, and very fast also (so perhaps it’s not related to connection speed). See the image below.
Things you can try:
- Use a different browser or Internet connection, if possible.
- Temporarily disable any Internet Security Suite (some have been found to block the simulation)
- If possible, check on a different PC.

Yes, this is normal, as you are already on the last section of the course.
