Problem with inserting model

edit

When I'm following the tutorial, I meet a problem after creating my first model configuration. In the following command:

mkdir -p ~/.gazebo/models/my_robot

I change the direction "~/.gazebo/models/my_robot" with my own file direction, because I don't find the file name of the given example.

After that, during the 'gedit' command for the 'model.sdf' file and 'model.config' file, I do the same action for gedit in the my same model direction.

Then the problem occurs, when I run the gazebo and try to find my_robot file in the "Insert" interface, I can't find the model direction which I set. My model direction is: '/home/iclab/gazebo_models/my_robot' But it didn't appear in the Insert list.

Now I can't find the model direction in the Insert interface, resulting I can't do anything with my model. I've been stuck in this problem for days, hope someone can help me. Thanks a lot!

Update

I've try the method in here

I use

sudo gedit ~/.bashrc

and add this

export GAZEBO_MODEL_PATH=/home/iclab/gazebo_models/my_robot:$GAZEBO_MODEL_PATH

My model locates in my_robot file. After I save the changes, I close and open gazebo again, but the Insert interface still remain the same:

I don't know what is going on here...
