I imagine folks do this all the time, but somehow I can't find a standard Dockerfile or osrf image like osrf/ros2:source.

I see the tag mentioned here, but it doesn't exist: https://hub.docker.com/r/osrf/ros2/

Obviously I can just build my own, but I just wanted to ask in case I'm missing something obvious.

Seems like a dumb question, but I can't find the answer.

I see that image_proc::ResizeNode subscribes to /camera_info, and then generates a new CameraInfo message with the scaled intrinsics. But it publishes this scaled camera info on the the same topic. The messages are identical except for fx, fy, cx and cy. How can a downstream node tell them apart? How does this work with image_transport?

Thanks.

This is an old message, but I recently stumbled upon it looking for the same information. The upshot is that mavros doe

You can nest message types inside message types, service types and action types in both ROS1 and ROS2. See section 2.1.

Nice! Thanks for posting.

In Foxy, kdl_parser declared a PUBLIC dependency on urdf, but did not export that dependency. It looks like this was fix

I don't see a call to ament_package() in your CMakeLists.txt file. See: https://docs.ros.org/en/humble/How-To-Guides/Ame

foo is std::vector<int64_t>. Yes, that is the default.

declare_parameter also gets the parameter. But if you need to use get_parameter, it looks like that isn't possible right

I was looking for an example that had time.sleep() in it to simulate a long-running calculation. I actually found some g

The Fibonacci action demo is nice, but it doesn't support cancellation.

I added a custom cancel_callback, called it from ros2 action send_goal, and tried to cancel by hitting ctrl-C, but it doesn't seem to work. I suspect that's because execute_callback is blocking.

What is a preferred pattern for handling long-running actions in rclpy with cancellation? Any examples / demos / tutorials?

Thanks.

Whoops, I looked at the rclpy demos, but forgot about the rclpy examples. There are several server examples showing how

I have not tried it, but I see that this features was added to rclpy Rolling just 2 days ago: https://github.com/ros2/r

Thanks for this example. Is there a way to support long-running actions? E.g., in https://github.com/ros2/demos/blob/hum

I was able to work around this by modifying usb_cam. I opened a bug: https://github.com/ros-drivers/usb_cam/issues/79

I suggest you start a new question for Windows.

The fact that the failure is in cvtColor suggests that there's a problem with your gstreamer pipeline. Have you gotten t

Hi, I'm trying to use ros-tooling/action-ros-ci with a private repo. Here are the contents of .github/workflows/build_test.yml:

name: ROS CI
on:
  pull_request:
  push:
    branches:
      - main

jobs:
  foxy_build:
    name: foxy_build
    runs-on: ubuntu-20.04
    steps:
      - uses: actions/checkout@v2.3.4
      - uses: ros-tooling/setup-ros@0.3.2
        with:
          required-ros-distrutions: foxy
      - uses: ros-tooling/action-ros-ci@0.2.5
        with:
          package-name: gst_tools
          target-ros2-distro: foxy

IIUC, this should "just work" with a private repo. But I'm consistently getting github action errors like this:

In comparison, I have zero problems with creating a private repo using https://github.com/ros-tooling/action... which uses tooling/action-ros2-lint rather than ros-tooling/action-ros-ci.

Any clues?

Thanks.
