Gazebo Developer pages¶

Gazebo simulates multiple robots in a 3D environment, with extensive dynamic interaction between objects. This is a core physics simulator that is integrated deeply into NRP at this moment.

The NRP gazebo repository contains the fork of the http://gazebosim.org project of version 11.

Installation¶

The detailed instructions for stand-alone installation with all the dependencies are located at http://gazebosim.org/install

Installation from source¶

Installation of the Gazebo for the NRP can be performed as a part of NRP source installation. In case the dependencies are installed, then run:

# from the gazebo repository directory
mkdir build/
cd build/
cmake -DCMAKE_INSTALL_PREFIX=$HOME/.local .. make install  SDFormat supported cmake parameters at configuring time: • USE_HOST_CFLAGS (bool) [default True] Check the building machine for supported compiler optimizations and use them to build the software. • USE_UPSTREAM_CFLAGS (bool) [default True] Use the recommend gazebo developers compiler optimizations flags • ENABLE_TESTS_COMPILATION (bool) [default True] Enabled or disable the test suite compilation. • USE_LOW_MEMORY_TEST (bool) [default False] Use reduced version of tests which need less quantity of RAM memory available. • FORCE_GRAPHIC_TESTS_COMPILATION (bool) [default False] Ignore system checks to look for graphic and acceleration support and compile all the test suite. • ENABLE_SCREEN_TESTS (bool) [default True] Enable or disable tests that need screen rendering to run properly. Headless machines or machines with the screen turned off should set this to False Uninstallation¶ To uninstall the software installed with the previous steps: #from the gazebo repository directory cd build/ sudo make uninstall  Debian package¶ For speed-up of the Docker images build and deploy, we pre-build DEB package for NRP version of Gazebo. We do not distribute this package, because it has limited usage, as soon as we prepare it to be installed into NRP Docker image and consider image’s file system structure. You can read here about the procedure of Debian packages building that we use. You can also create Debian package for your purposes: # from the gazebo repository directory mkdir build/ cd build/ cmake -DCMAKE_INSTALL_PREFIX=$HOME/.local ..
make package


The resulting DEB package will be created in the build directory. Note, that the further installation path is determined by CMAKE_INSTALL_PREFIX
