原因

Gazebo try to collect models from http://gazebosim.org/models but there is something wrong.

OR the folder ~/.gazebo/models does not exist and Gazebo simulator can not start.

解决方式

运行

wget -r -R "index\.html*" "http://models.gazebosim.org" --reject=tar.gz

Got all models from gazebosim and copy them into ~/.gazebo/models folder and everything will be ok.
