I have difficulties in loading custom worlds in gazebo to be with rosbot.
When i used simple custom world in rosbot.launch, rosbot dropped down and disappeared.
I am not familiar with xml and urdf so kindly let me know the points that i would be wrong.
If you are creating your custom world, the behavior you are describing may indicate that you usually did not add a floor, so the ROSbot is falling due to simulated gravity. I encourage you to use the ready-made Husarion worlds available in the repository below:
Thank you for your support.
