1、配置,提升下载速度
启动
- $ cd clash-for-linux
- $ sudo bash start.sh
- $ source /etc/profile.d/clash.sh
- $ proxy_on
关闭
- $ cd clash-for-linux
- $ sudo bash shutdown.sh
- $ proxy_off
2、安装PX4开源无人机
git clone https://github.com/PX4/PX4-Autopilot.git --recursive
在PX4根目录执行
安装时如果下载较慢,则需要加快下载速度
bash ./PX4-Autopilot/Tools/setup/ubuntu.sh --no-sim-tools --no-nuttx
sudo apt-get install protobuf-compiler libeigen3-dev libopencv-dev -y
如果有安装失败的情况,执行
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
bash ./PX4-Autopilot/Tools/setup/ubuntu.sh --fix-missing
更新并重启系统
**注意:下方命令为继续下载未下载完的组件,如在github执行clone时出错可执行命令
git submodule update --init --recursive
打开gazebo
重启后
make distclean
打开gazebo
make px4_sitl_default gazebo
加载px4 v3部件
加载px4 v3部件
make px4_fmu-v3_default
**报错:arm-none-eabi-gcc
sudo apt-get install gcc-arm-none-eabi
3、利用ros查看无人机飞行
- cd PX4-Autopilot
- make px4_sitl_default gazebo
- 终端输入 commander takeoff ,可以看到无人机起飞
- 终端输入 commander land , 可以看到无人机降落
添加环境变量
- source ~/px4/PX4-Autopilot/Tools/simulation/gazebo-classic/setup_gazebo.bash ~/px4/PX4-Autopilot ~/px4/PX4-Autopilot/build/px4_sitl_default
- export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/px4/PX4-Autopilot
- export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/px4/PX4-Autopilot/Tools/simulation/gazebo-classic/sitl_gazebo-classic
安装mavros
sudo apt-get install ros-noetic-mavros ros-noetic-mavros-extras
sudo /opt/ros/noetic/lib/mavros/install_geographiclib_datasets.sh
**注意:如果未执行上方安装命令,则会报错 UAS:GeographicLib exception: File not readable
执行命令
roslaunch mavros px4.launch
如果出现FCU: DeviceError:serial:open: No such file or directory报错,是
由于没有链接硬件所致。
也可以参考树莓派串口通信设置 - 知乎,解决serial0和ttyAMA0映射关系问题
4、安装QGC
Download and Install · QGroundControl User Guidehttps://docs.qgroundcontrol.com/master/en/getting_started/download_and_install.html
- On the command prompt enter:
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
- Logout and login again to enable the change to user permissions.
- Download QGroundControl.AppImage.(下载后的文件放到指定文件夹中)
- Install (and run) using the terminal commands:
chmod +x ./QGroundControl.AppImage ./QGroundControl.AppImage (or double click)
5、px4仿真
启动gazebo、mavros、px4.launch等
roslaunch px4 mavros_posix_sitl.launch
如果启动成功,可以使用commander takeoff / commander land执行起飞和降落
