XTDrone源码下载
git clone https://gitee.com/robin_shaun/XTDrone.git
cd XTDrone
git submodule update --init --recursive
安装编译插件
cd ~/catkin_ws
cp -r ~/XTDrone/sitl_config/gazebo_ros_pkgs src/
catkin build
之后验证是否安装成功:
roscore
source ~/catkin_ws/devel/setup.bash
rosrun gazebo_ros gazebo
在安装之前,请先更新软件库:
sudo apt-get update
sudo apt-get upgrade
开始安装:
sudo apt install ros-melodic-mavros ros-melodic-mavros-extras
wget https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/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
git clone https://github.com/PX4/PX4-Autopilot.git
mv PX4-Autopilot PX4_Firmware
cd PX4_Firmware
git checkout -b xtdrone/dev v1.11.0-beta1
git submodule update --init --recursive
sudo make px4_sitl_default gazebo
编译完成后,会弹出Gazebo界面,将其关闭即可。
gedit ~/.bashrc
之后打开~/.bashrc,加入以下代码,注意路径匹配,前两个source顺序不能颠倒。
source ~/catkin_ws/devel/setup.bash
source ~/PX4_Firmware/Tools/setup_gazebo.bash ~/PX4_Firmware/ ~/PX4_Firmware/build/px4_sitl_default
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4_Firmware
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4_Firmware/Tools/sitl_gazebo
之后再source一下:
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
但是大概率会报这个错:
ERROR [px4] is_server_running: failed to create lock file: /tmp/px4_lock-0, reason=Permission denied
ERROR [px4_daemon] error binding socket /tmp/px4-sock-0, error = Address already in use
ERROR [px4] is_server_running: failed to create lock file: /tmp/px4_lock-0, reason=Permission denied
ERROR [px4] Failed to communicate with daemon: Permission denied
原因是锁的权限不够。注意下面的usename 是自己的用户名
cd /tmp
sudo chmod 777 px4_lock-0
sudo chmod 777 px4-sock-0
sudo chown username px4_lock-0
sudo chown username px4-sock-0
成功打开gazebo后,我们检查与mavros连接是否正常
rostopic echo /mavros/state
若connected: True,则说明MAVROS与SITL通信成功。如果是false,一般是因为.bashrc里的路径写的不对,仔细检查。
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
下载QGroundControl.AppImage
下载完成后,进入到QGroundControl.AppImage相应的目录,修改QGroundControl.AppImage权限:
chmod +x ./QGroundControl.AppImage
然后双击QGroundControl.AppImage或者在终端切换到QGroundControl.AppImage目录后,输入以下命令即可打开地面站:
./QGroundControl.AppImage
cp sensing/gimbal/gazebo_gimbal_controller_plugin.cpp ~/PX4_Firmware/Tools/sitl_gazebo/src/
cp sitl_config/init.d-posix/rcS ~/PX4_Firmware/ROMFS/px4fmu_common/init.d-posix/
cp sitl_config/worlds/* ~/PX4_Firmware/Tools/sitl_gazebo/worlds/
cp -r sitl_config/models/* ~/PX4_Firmware/Tools/sitl_gazebo/models/
cp -r sitl_config/launch/* ~/PX4_Firmware/launch/
cd ~/.gazebo/models/
rm -r stereo_camera/ 3d_lidar/ 3d_gpu_lidar/ hokuyo_lidar/
由于修改了PX4 sitl_gazebo中的gazebo_gimbal_controller_plugin.cpp(源代码不能控制多无人机的云台),要再编译一次。
cd ~/PX4_Firmware
sudo make px4_sitl_default gazebo
每次编译PX4后都要重新添加锁的权限:(username是自己的用户名)
cd /tmp
sudo chmod 777 px4_lock-0
sudo chmod 777 px4-sock-0
sudo chown username px4_lock-0
sudo chown username px4-sock-0
source ~/.bashrc
cd ~/PX4_Firmware
roslaunch px4 indoor1.launch
Gazebo启动后,在另一个终端运行(注意要等Gazebo完全启动完成,或者可能脚本会报错)
cd ~/XTDrone/communication/
python multirotor_communication.py iris 0
终端出现: iris_0: communication initialized ,则表示与0号iris成功建立通信,之后在另一个终端运行
cd ~/XTDrone/control/keyboard
python multirotor_keyboard_control.py iris 1 vel
此时上面的终端出现:iris_0:HOVER,则表示准备成功
