Hello,

I'm trying to run orbslam2 on a tello drone using ros 2 (foxy distro, ubuntu 20.04). For the purpose, I am trying to use this repository:

https://github.com/tentone/tello-ros2

What I managed to do successfully so far is:

  • Install all dependencies, running scripts/install.sh
  • Build the 3 packages of the repository (tello/tello_control/tello_msg) running scripts/build.sh, which is basically running colcon build on the 3 packages:

    colcon build --symlink-install --packages-select tello tello_control tello_msg

  • Build the ORBSLAM-2 package, through the instructions in the scripts/orbslam.sh script

Now I am trying to compile the nodes in the slam/src/orbslam2 folder. However when I run colcon build in that folder, I get the following error:

I looked at the source code and found something strange. A subscription must be defined with a QoS, which is surprisingly not mentioned in the code. Therefore, please edit the source code (tello-ros2/slam/src/orbslam2/src/monocular/monocular-slam-node.cpp) by adding appropriate QoS. An example is shown below:

m_image_subscriber = this->create_subscription<ImageMsg>("camera", 10, std::bind(&MonocularSlamNode::GrabImage, this, std::placeholders::_1));

Please inform us if the problem persists.

Thanks, indeed I arrived to the same solution after googling and I found some similar question posted on another github repository. Similarly, I fixed the error on the create_publisher function as well. Thank you!
