搭建无人机仿真环境之PX4安装

安装依赖包

sudo apt install python3-pip
pip3 install --user pandas -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip3 install --user jinja2 -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip3 install --user empy -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip3 install --user packaging -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip3 install --user toml -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip3 install --user numpy -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
pip3 install --user pyquaternion -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

如果遇到问题：

安装包出现Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError

解决办法如：

pip install pandas -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

下载固件

git clone https://github.com/PX4/Firmware
mv Firmware PX4_Firmware
cd PX4_Firmware
git checkout -b xtdrone/dev v1.11.0-beta1
git submodule update --init --recursive
make posix_sitl_default gazebo

如果遇到git clone 速度非常慢，可以将原本的网站中的http://github.com 进行替换为github.com.cnpmjs.org。例如 git clone https://github.com.cnpmjs.org/PX4/Firmware

git submodule update --init --recursive中遇到的问题

问题1

如果使用镜像github.com.cnpmjs.org进行git clone ，在执行git submodule update --init --recursive时出现：

~/PX4_Firmware$ git submodule update --init --recursive
子模组 'Tools/jMAVSim'（https://github.com.cnpmjs.org/PX4/jMAVSim.git）未对路径 'Tools/jMAVSim' 注册
子模组 'Tools/sitl_gazebo'（https://github.com.cnpmjs.org/PX4/sitl_gazebo.git）未对路径 'Tools/sitl_gazebo' 注册
子模组 'boards/atlflight/cmake_hexagon'（https://github.com.cnpmjs.org/PX4/cmake_hexagon.git）未对路径 'boards/atlflight/cmake_hexagon' 注册
子模组 'mavlink/include/mavlink/v2.0'（https://github.com.cnpmjs.org/mavlink/c_library_v2.git）未对路径 'mavlink/include/mavlink/v2.0' 注册
子模组 'platforms/nuttx/NuttX/apps'（https://github.com.cnpmjs.org/PX4/NuttX-apps.git）未对路径 'platforms/nuttx/NuttX/apps' 注册
子模组 'platforms/nuttx/NuttX/nuttx'（https://github.com.cnpmjs.org/PX4/NuttX.git）未对路径 'platforms/nuttx/NuttX/nuttx' 注册
子模组 'platforms/qurt/dspal'（https://github.com.cnpmjs.org/ATLFlight/dspal.git）未对路径 'platforms/qurt/dspal' 注册
子模组 'src/drivers/gps/devices'（https://github.com.cnpmjs.org/PX4/GpsDrivers.git）未对路径 'src/drivers/gps/devices' 注册
子模组 'src/drivers/uavcan/libuavcan'（https://github.com.cnpmjs.org/PX4/uavcan.git）未对路径 'src/drivers/uavcan/libuavcan' 注册
子模组 'src/lib/ecl'（https://github.com.cnpmjs.org/PX4/ecl.git）未对路径 'src/lib/ecl' 注册
子模组 'src/lib/matrix'（https://github.com.cnpmjs.org/PX4/Matrix.git）未对路径 'src/lib/matrix' 注册
子模组 'src/modules/micrortps_bridge/micro-CDR'（https://github.com.cnpmjs.org/PX4/micro-CDR.git）未对路径 'src/modules/micrortps_bridge/micro-CDR' 注册

解决方法：
检查 .gitmodule文件中的url格式
按照以下方法更换一下即可：

gedit .gitmodules

将.gitmodules文件中所有github.com替换为github.com.cnpmjs.org，例如
[submodule “mavlink/include/mavlink/v2.0”]
path = mavlink/include/mavlink/v2.0
url = https://github.com.cnpmjs.org/mavlink/c_library_v2.git
branch = master

修改完后，再次执行：

git submodule sync

问题2

dj@dj-virtual-machine:~/PX4_Firmware$ git submodule update --init --recursive
fatal: Needed a single revision
无法在子模组路径 'Tools/jMAVSim' 中找到当前版本

解决方法:
删除对应文件夹，如删除文件夹 jMAVSim

make posix_sitl_default gazebo中遇到的问题

问题1

CMake Error at CMakeLists.txt:32 (find_package):
  By not providing "Findgazebo.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "gazebo", but
  CMake did not find one.

  Could not find a package configuration file provided by "gazebo" with any
  of the following names:

    gazeboConfig.cmake
    gazebo-config.cmake

  Add the installation prefix of "gazebo" to CMAKE_PREFIX_PATH or set
  "gazebo_DIR" to a directory containing one of the above files.  If "gazebo"
  provides a separate development package or SDK, be sure it has been
  installed.

解决方法：

sudo apt-get install libgazebo9-dev

问题2

解决方法：

sudo apt-get install libgstreamer-plugins-base1.0-dev

问题3

运行Gazebo出现：[Err] [REST.cc:205] Error in REST request

解决方法：
打开编辑~/.ignition/fuel/config.yaml文件

sudo gedit ~/.ignition/fuel/config.yaml

首先注释 url : https://api.ignitionfuel.org
然后添加 url: https://api.ignitionrobotics.org

servers:
  -
    name: osrf
    url: https://api.ignitionrobotics.org  
# url: https://api.ignitionfuel.org

重新启动即可
