These scripts are used at NPS to install and update NASA's Astrobee simulator based on its installation guide.
To install the Astrobee Simulator just execute the Astrobee_install.sh:
./Astrobee_install.sh
After the install the freeflyer, freeflyer_build, freeflyer_install, and freeflyer_android will be located in ~/Documents.
First, source freeflyer,
source ~/Documents/freeflyer_build/native/devel/setup.bash
and then launch the simulator
roslaunch astrobee sim.launch dds:=false robot:=sim_pub rviz:=true sviz:=true
When the NASA's Astrobee simulator repository is updated you can run the update script to update your local copy of the simulator (it simply pulls the changes and re-compiles).
./Astrobee_update.sh
