Saved scenarios that can be loaded automatically from Gazebo without the need of setting manually, e.g., the robot position.
To use the iRonCub worlds (tested only on Ubuntu): append to the GAZEBO_RESOURCE_PATH in your .bashrc the folders iRonCub-Mk1_1_world and iRonCub-Mk1_world as follows:
source /usr/share/gazebo/setup.sh
export GAZEBO_RESOURCE_PATH=$GAZEBO_RESOURCE_PATH:$IRONCUB_SOFTWARE_SOURCE_DIR/models/world/iRonCub-Mk1_1_world
Once the words are added to Gazebo resurce path, call Gazebo followed by the name of the world file, e.g. gazebo iRonCub_Mk1_1_world.
