https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

1. Wireless connection with jetson (ssh)

• connect both laptop and jetson to TP-link course wifi
• on laptop, run ssh jetson@10.42.0.103 password is jetson
• on flight, connect the green power board to the lipo battery

2. Wiring connecction with jetson (usage: code dev on jetson)

• require: monitor, mouse, keyboard
• connect jetson to a wifi with internet service

3. Jetson nano fan: in terminal run fan_on or fan_off

• their command are encoded in ~/.bashrc: eg. sudo sh -c 'sudo echo 255 > /sys/devices/pwm-fan/target_pwm'

4. Build

• colcon build --symlink-install

1. Start MAVROS & PX4
   • ros2 launch px4_autonomy_modules mavros.launch.py
   • If not working correctly, ls /dev/ttyUSB*, expected to see ttyUSB0
2. Start RealSense Pose Estimation
   • ros2 launch realsense2_camera rs_launch.py
3. Run the Drone Communication Node
   • ros2 run rob498_drone comm_node
4. Check VICON & RealSense Pose Data (Optional)
   • ros2 topic echo /vicon/ROB498_Drone/ROB498_Drone
   • ros2 topic echo /camera/pose/sample
5. Send Commands Using ROS 2 Services (TA will run this during the actual test)
   • ros2 service call rob498_drone_3/comm/launch std_srvs/srv/Trigger (<-)
   • ros2 service call rob498_drone_3/comm/test std_srvs/srv/Trigger
   • ros2 service call rob498_drone_3/comm/land std_srvs/srv/Trigger (<-)
   • ros2 service call rob498_drone_3/comm/abort std_srvs/srv/Trigger

ros2 launch px4_autonomy_modules mavros.launch.py

1. realsense to mavros ros2 topic echo /mavros/vision_pose/pose

2. vicon to mavros ros2 topic echo /mavros/local_position/pose

3. start task3 node ros2 run rob498_drone task3

ros2 launch realsense2_camera rs_launch.py

ros2 run realsense_tracking t265_node --> RGB-D Map

ros2 run rob498_drone project --> Planner

1. ros2 bag record /depth_image /rgb_image /camera/pose/sample /vicon/ROB498_Drone/ROB498_Drone -o rosbag_1
2. Replay the bag and run ros2 run realsense_tracking save_bag which generates a folder with *.npy files
3. Then you can visualize it by running python3 src/scripts/planner_clean.py

python3 src/scripts/inference_actuation.py --> actuates the Arduino code

• (For Micro XRCE-DDS only) Upgrade your cmake to above 3.22 (https://answers.ros.org/question/293119/)
  • tar -xzvf cmake-3.30.8.tar.gz # source tar.gz (no distro)
  • cd ~/Downloads/cmake-3.30.8/
  • ./bootstrap --prefix=$HOME/cmake-install
  • make -j$(nproc)
  • sudo make install
  • echo 'PATH=$HOME/cmake-install/bin:$PATH' >> ~/.bashrc
  • echo 'CMAKE_PREFIX_PATH=$HOME/cmake-install:$CMAKE_PREFIX_PATH' >> ~/.bashrc
  • NEVER RUN purge -autoremove cmake!!
• Upgrade your numpy to above 1.24 (it might affect ROS2 foxy packages but will
  • sudo apt remove python3-numpy
  • pip3 install numpy
  • sudo apt install ros-foxy-desktop python3-argcomplete
• Setup PX4-Autopilot following (PX4/PX4-Autopilot#21117)
  • git clone https://github.com/PX4/PX4-Autopilot.git
  • cd PX4-Autopilot.git
  • git checkout v1.11.3
  • git submodule update --init --recursive
  • bash ./PX4-Autopilot/Tools/setup/ubuntu.sh --no-nuttx
  • make px4_sitl gazebo
• (Optional) Setup Micro XRCE-DDS Agent & Client (https://github.com/PX4/PX4-user_guide/blob/main/tr/ros2/user_guide.md)
  • you don't need the Micro XRCE-DDS Agent unless you are running ROS 2 on a microcontroller (using Micro-ROS)
