Ubuntu20.04搭建PX4仿真环境及XTDrone开发平台(最详细最明白)_ubuntu安装px4_哒哒哒,啥也不会的博客-CSDN博客
安装过程:
简单地说,XTDrone安装包括几个部分:ROS安装、Gazebo安装、marvos安装和PX4 安装,XTDrone下载和配置。
依赖安装
首先安装一个aptitude以解决出现的依赖问题
依赖问题的报错形式:
有一些软件包无法被安装。如果您用的是 unstable 发行版,这也许是
因为系统无法达到您要求的状态造成的。该版本中可能会有一些您需要的软件
包尚未被创建或是它们已被从新到(Incoming)目录移出。
下列信息可能会对解决问题有所帮助:
下列软件包有未满足的依赖关系:
fcitx : 依赖: fcitx-data 但是它将不会被安装
E: 无法修正错误,因为您要求某些软件包保持现状,就是它们破坏了软件包间的依赖关系。
使用sudo apt install aptitude
安装aptitude,在一定程度上能解决依赖问题
先从语雀下载压缩包PX4_Firmware,并将该zip压缩包放置到Ubuntu主目录下,使用unzip命令解压,没用unzip命令工具,使用sudo apt install unzip
或sudo pip install unzip
,然后解压后,将其命名为PX4_Firmware,使用cd PX4_Firmware/Tools/setup
,其中有一个requements.txt文件:
argcomplete
argparse>=1.2
cerberus
coverage
empy>=3.3
future
jinja2>=2.8
jsonschema
kconfiglib
lxml
matplotlib>=3.0.*
numpy>=1.13
nunavut>=1.1.0
packaging
pandas>=0.21
pkgconfig
psutil
pygments
wheel>=0.31.1
pymavlink
pyros-genmsg
pyserial
pyulog>=0.5.0
pyyaml
requests
setuptools>=39.2.0
six>=1.12.0
toml>=0.9
这是官当给出的PX4所需依赖。
在PX4_Firmware/Tools/setup
目录下执行命令:
bash ubuntu.sh --no-sim-tools
不加参数 --no-sim-tools,就会自动安装ubuntu版本对应的gazebo及gazebo-dev,和javsim等仿真依赖
sudo apt install ninja-build exiftool ninja-build protobuf-compiler libeigen3-dev genromfs xmlstarlet libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev python-pip python3-pip gawk
pip2 install pandas jinja2 pyserial cerberus pyulog==0.7.0 numpy toml pyquaternion empy pyyaml
pip3 install packaging numpy empy toml pyyaml jinja2 pyargparse
记录
语雀文档中提到的一个错误:
Collecting pandas
Using cached https://files.pythonhosted.org/packages/64/f1/8fdbd74edfc31625d597717be8c155c6226fc72a7c954c52583ab81a8614/pandas-1.1.2.tar.gz
Complete output from command python setup.py egg_info:

^
SyntaxError: invalid syntax
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-qtvsjq8t/pandas/
如果出现该错误,可以先更新setuptools 和 pip。(我没出现过)
更新setuptools命令:
pip install --upgrade setuptools
#若未报错不需要输入这两行命令
python -m pip install --upgrade pip
放置一个清华源安装地址:
https://pypi.tuna.tsinghua.edu.cn/simple
如果报错:网络连接不上,或者下载一半就不下了,然后报错的情况,就在上面的命令后面写上:
pip2 install pandas jinja2 pyserial cerberus pyulog==0.7.0 numpy toml pyquaternion empy pyyaml -i https://pypi.tuna.tsinghua.edu.cn/simple
可能的报错如下:

ROS一键安装
鱼香肉丝开发的ubuntu一键安装挺不错的,避免了自己安装的很多麻烦,包括编译上的麻烦,换源等诸多问题。
wget http://fishros.com/install -O fishros && . fishros
Ubuntu 20.04是最后一个支持ROS1的,对应安装ROS1的Noetic,(Ubuntu 22.04只能安装ROS2,ROS2都不是很熟,我安装试了一下,不太会用,所以又用20.04了)
安装时间会比较漫长:安装结束后,使用roscore
命令启动ros(ROS2中不再这样启动),出现一大段信息,包括如下信息,即安装成功。

文档里有推荐安装rosdep,
rosdep是ros的依赖项管理工具,在安装完ros之后建议安装此工具,但是在rosdep init和 rosdep update时国外的网站实在令人头疼。所以使用rosdepc
所以安装一下:
sudo pip install rosdepc
rosdepc需要进行初始化和更新
sudo rosdepc init
rosdepc update
如果之前没有catkin_ws,则需要新建工作空间,之后除去PX4仿真环境启动外,其余ROS相关工程在此工作空间下管理。
文档中推荐做法,估计是为了集中管理?
mkdir -p ~/catkin_ws/src
mkdir -p ~/catkin_ws/scripts
cd catkin_ws && catkin init # 使用catkin_make话,则为cd catkin_ws/src && catkin_init_workspace
catkin build # 使用catkin_make话,则为 cd .. && catkin_make
gedit ~/.bashrc
在下面写入:source ~/catkin_ws/devel/setup.bash #先写好source路径
关闭文件,在终端执行
source ~/.bashrc
catkin build需要先装catkin-tools(sudo apt install python3-catkin-tools
),安装好Ubutu系统应该会有这个命令工具。
文档里说要卸载之前的Gazebo,CSDN博客里给出以下原因
XTDrone一般用gazebo9进行仿真,而在安装ros noetic时会自动安装gazebo11以及对应的gazebo-ros插件,这里我们需要卸载,然后安装gazebo9以及肖老师修改过的gazebo-ros插件。
感觉也可以用gazebo11来进行仿真,如果比较有时间的话,可以试一试。
感觉Gazebo 11也不是不行,文档里给出可以
- 选用Alternative installation: step-by-step的安装方式
- 如果安装有依赖问题,可以使用sudo aptitude install gazebo11,选择合理的依赖解决办法(别把ROS删了)
- 按步骤装完Gazebo后,升级所有的包 sudo apt upgrade,这样能保证gazebo所有依赖版本一致
卸载Gazebo
sudo apt-get remove gazebo*
sudo apt-get remove libgazebo*
sudo apt-get remove ros-noetic-gazebo* #kinetic melodic对应修改
安装Gazebo
a、添加软件仓库
sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
b、获取密钥
wget https://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
c、更新软件源
sudo apt-get update
d、安装Gazebo 9
sudo apt-get install gazebo9
sudo apt-get install libgazebo9-dev #一定要记得这个
安装Gazebo 11
sudo apt-get install gazebo11
sudo apt-get install libgazebo11-dev
插件修改的重新编译
安装依赖:
sudo apt-get install ros-noetic-moveit-msgs ros-noetic-object-recognition-msgs ros-noetic-octomap-msgs ros-noetic-camera-info-manager ros-noetic-control-toolbox ros-noetic-polled-camera ros-noetic-controller-manager ros-noetic-transmission-interface ros-noetic-joint-limits-interface
然后克隆并编译Gazebo的插件gazebo_ros_pkgs,放在~/catkin_ws/src
下(如果编译时还缺其他的依赖,同上方法安装)
cd ~/catkin_ws/src
git clone https://github.com/ros-simulation/gazebo_ros_pkgs.git
cd ~/catkin_ws
catkin build
上面需要使用git命令工具,如果没安装过
sudo apt install git
catkin build
后的结果,成功的情况是不会有Error的,(红色的Error看得人心惊肉跳)

问题:git clone https://github.com/ros-simulation/gazebo_ros_pkgs.git
有时候无法正常克隆库,会报错。
解决方案一:
-
在github网站上下载适用于自己ROS版本的压缩包ros-simulation/gazebo_ros_pkgs: Wrappers, tools and additional API’s for using ROS with Gazebo (github.com)
-
将压缩包放到~/catkin_ws/src目录下解压缩,一般下载下来的压缩包是zip文件,需要使用unzip命令工具。使用
pip install unzip
命令安装 -
使用
cd ~/catkin_ws
和catkin build
进行编译。
编译通过后使用命令:
roscore
开始ros服务,使用命令
source ~/catkin_ws/devel/setup.bash
rosrun gazebo_ros gazebo
开启gazebo,查看安装是否成功。
Gazebo有很多开源的模型文件,📎models.zip下载后将该附件解压缩后放在~/.gazebo
中,此时在~/.gazebo/models/
路径下可以看到很多模型。如果不做这一步,之后运行Gazebo仿真,可能会缺模型,这时会自动下载,Gazebo模型服务器在国外,自动下载会比较久。
Marvos安装
注意,mavros-extras一定别忘记装,否则视觉定位将无法完成
sudo apt install ros-noetic-mavros ros-noetic-mavros-extras # for ros-noetic
wget https://gitee.com/robin_shaun/XTDrone/raw/master/sitl_config/mavros/install_geographiclib_datasets.sh
sudo chmod a+x ./install_geographiclib_datasets.sh
sudo ./install_geographiclib_datasets.sh #这步需要装一段时间
PX4 安装
安装方式:从语雀下载压缩包PX4_Firmware,使用该压缩包解压编译,从git上下载的代码可能很多方面都要修改,而且下载速度很慢。
使用该包会报错:
[0/1] Re-running CMake...
CMake Error: The source directory "/home/robin/PX4_Firmware_13" does not exist.
Specify --help for usage, or press the help button on the CMake GUI.
FAILED: build.ninja
/usr/bin/cmake -H/home/robin/PX4_Firmware_13 -B/home/robin/PX4_Firmware_13/build/px4_sitl_default
ninja: error: rebuilding 'build.ninja': subcommand failed
make: *** [Makefile:230: px4_sitl_default] Error 1
主要是编译的CMakeCache.txt文件中的路径都是/home/robin/PX4_Firmware_13
(肖老师自己电报的路径),可能编译过不了,然后自己改也是比较麻烦,我尝试改了CMakeCache.txt文件中路径问题,还是报错,还需要改build.ninja文件、cmake_install.cmake等等。这两个文件都在PX4_Firmware_13/build/px4_sitl_default
目录下。~~(反正要改很多文件,你就改吧,我是把这个目录下的编译文件都改了一遍,但还是有报错)
这样看用git命令也是可以,可以通过git 克隆代码
git clone -b v1.13.2 https://github.com/PX4/PX4-Autopilot.git --recursive
git clone -b v1.13.2 https://github.com.cnpmjs.org/PX4/PX4-Autopilot.git --recursive
mv PX4-Autopilot PX4_Firmware
cd PX4_Firmware
git checkout -b xtdrone/dev v1.13.2
git submodule update --init --recursive
make px4_sitl_default gazebo
好叭,最后还是用的VS code整体修改才可以编译
chmod +x Tools/check_submodules.sh
chmod +x Tools/sitl_run.sh
最好发现还是不行,报错是:
Error creating PX4_Firmware/build/px4_sitl_default/etc -> /home/sunx/PX4_Fir
这个错误还显示不全,应该是软连接问题。
克隆又克隆不下来,编译又编译不过,丢。
新的可行方法:
-
下载语雀文档中的PX4包,解压后进入PX4_Firmware然后使用命令
rm -rf build
,删除build文件夹,然后使用命令mkdir build
-
使用命令重新编译
cd build cmake .. make
-
使用命令
git checkout -b xtdrone/dev v1.13.2 git submodule update --init --recursive make px4_sitl_default gazebo
终于编译成功了。花了一天和一个晚上
修改 ~/.bashrc,加入以下代码,注意路径匹配,前两个source顺序不能颠倒
#配好好路径
gedit ~/.bashrc
在里面写入:
source ~/catkin_ws/devel/setup.bash
source ~/PX4_Firmware/Tools/setup_gazebo.bash ~/PX4_Firmware/ ~/PX4_Firmware/build/px4_sitl_default
#确保文件最底部是export,而不是source
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4_Firmware
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4_Firmware/Tools/sitl_gazebo
关闭文件,在终端执行
source ~/.bashrc
然后运行如下命令,此时会启动Gazebo,如下图所示。
cd ~/PX4_Firmware
roslaunch px4 mavros_posix_sitl.launch
安装QTGroundControl
第一次安装该软件:
sudo usermod -a -G dialout $USER
sudo apt-get remove modemmanager -y
sudo apt install gstreamer1.0-plugins-bad gstreamer1.0-libav gstreamer1.0-gl -y
sudo apt install libqt5gui5 -y
sudo apt install libfuse2 -y
XTDrone下载安装

Changes should only be made to the template file `/home/sunx/PX4_Firmware/Tools/sitl_gazebo/models/typhoon_h480/typhoon_h480.sdf.jinja`. Remove `typhoon_h480.sdf` (after extracting your changes) to disable this overwrite protection.
解决方案:
find . -name "typhoon.sdf"
然后使用rm 命令删除该文件

删除文件后,这个问题就可以解决了。
注意,用ctrl+c关闭仿真进程,有可能没有把Gazebo的相关进程关干净,这样再启动仿真时可能会报错。如果出现这种情况,可以用killall -9 gzclient,killall -9 gzserver 这两个命令强行关闭gazebo所有进程。
killall -9 gzclient
killall -9 gzserver
