I have been following the all your provided steps to install flock2.

mkdir -p ~/flock2_ws/src cd ~/flock2_ws/src git clone https://github.com/clydemcqueen/flock2.git git clone https://github.com/ptrmu/fiducial_vlam.git git clone https://github.com/clydemcqueen/tello_ros.git cd .. source /opt/ros/eloquent/setup.bash If you didn't install Gazebo, avoid building tello_gazebo: colcon build --event-handlers console_direct+ --packages-skip tello_gazebo

Upon the last instruction of the Step 4. I faced an error shown below.

~/flock2_ws$ colcon build --event-handlers console_direct+ [0.542s] ERROR:colcon:colcon build: Duplicate package names not supported:

It looks like you have 2 copies of the 'tello_ros' directory. The only copy should be in '~/flock2_ws/src'.

Thanks for the swift answer. I have managed to fix that like ur solution stated above. However, it get another error as shown below.

flock2 CMake Error at CMakeLists.txt:49 (find_package): By not providing "Findtello_msgs.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "tello_msgs", but CMake did not find one. Could not find a package configuration file provided by "tello_msgs" with any of the following names: tello_msgsConfig.cmake tello_msgs-config.cmake Add the installation prefix of "tello_msgs" to CMAKE_PREFIX_PATH or set "tello_msgs_DIR" to a directory containing one of the above files. If "tello_msgs" provides a separate development package or SDK, be sure it has been installed.>

Please advice and thank you for the help.

That's strange. You may want to delete the workspace and start over.

ROS2 has some nice tutorials: https://index.ros.org/doc/ros2/Tutorials/Workspace/Creating-A-Workspace/

Thank you. I have managed to delete and recreating the workspace building was fine as well.. However, when I am trying to run launch_one.py, I would face some error message. [ERROR] [launch]: Caught exception in launch (see debug for traceback): executable 'vmap_node' not found on the libexec directory '/home/user/flock2_ws/install/fiducial_vlam/lib/fiducial_vlam' Pondering into the file system, I couldnt find any references of vmap_node.

Ah, there's a bug in the launch files: they are referring to the older vlam node names. I will fix this.
