Flight testing fixed-wing low altitude navigation in the Swiss Alps
Просмотров 64Месяц назад
Abstract Fixed-wing aerial vehicles provide an efficient way to navigate long distances or cover large areas for environmental monitoring applications. By design, they also require large open spaces due to limited maneuverability. However, strict regulatory and safety altitude limits constrain the available space. Especially in complex, confined, or steep terrain, ensuring the vehicle does not ...

PX4 Local Obstacle Avoidance in Mission Mode (PX4 Vision)
Просмотров 318Год назад
This video shows local obstacle avoidance being executed during a mission with the PX4 Vision vehicle. The original mission is planned to navigate to a waypoint and come back, and there is an unknown tree in between the waypoints. The video shows that the vehicle can successfully navigate around the obstacle(the tree) that was not known in the original mission plan. - Documentation: docs.px4.io...

How can I add envirnoment...?
Which software are you using for this simulation
Looks really cool! 👏🛩
which gcs is that?
why does it in roll directions
Great video. I couldn't find the documentation though for this simulation. Can you please share it?
nice
Could you give me some help? I would like to have Vehicle camera like you have in gazebo, but unfortunetly I can not recreate such behavior. PX4 documentation did not help. Thanks for any advice.
To use the camera at PX4 SITL, use px4_sitl gz_x500_mono_cam. To see the Image display at Gazebo Sim (GZ), press 3dots at the right-upper side of the screen, search there Image Display, and subscribe on /camera topic.
선생님 안녕하세요 영상 정말 잘 보고 있습니다. 드론 개발자로 전향하고 싶어 알아보던 중 우연히 유튜브를 발견했는데요 혹시 선생님께서 개발자가 되시기 전에 따라가셨던 로드맵 같은 것이 있을까요?? 찾아봐도 관련 레퍼런스가 너무 없는거 같아서요
Can this setup work, where Airsim is running on windows while the Gazebo (gzserver, gzclient) is working in linux (WSL2)
This world is not starting using make px4_sitl gazebo-classic_yosemite !!! Any idea
thanks for your sharing. I'm using the latest Px4 version, however i found that there is only x500 quadcopter, may i ask how do you add your custom model into simulation?
which CPU did you use? I'm using intel i7 but when I simulated with 4 quadcopters, gazebo is very slow..

Is it possible to change iris model with other iris models such iris with depth camera?
Yes, it is possible
in the rain!
Haha yes! And we did not crash!
I wonder which topic in mavros did you use for gliding, I'm having some difficulties here,Thank you for your answer already.
Detailed information can be found in the PR link added in the description
which version of px4
which version of QGC?
Hi, Can these multivehicles be commanded by Mavlink
Why bother if you aren't going to include an explanation or sound?
The explanation is in the description
Hello,Can you share the .launch file with me?
This is using PX4, which does not depend on ROS so there is no launch file. All information can be found in the px4 autopilot documentation
Maybe it's the ../PX4-Autopilot/launch/multi_uav_mavros_sitl.launch file. However, drones are specified as iris. I saw it like typhoon_h480 in your video. That's why I wanted to ask. Thanks
This is a nice video, thank you for your contribution. I wonder how did you assign these setpoints for gliding? In offboard mode when I assigned setpoints through a code, I could not obtain gliding. Thank you for your answer already.
It's really cool! I just wonder ... is it possible to track the trajectory while keeping the specific angle?
Yes, but not out of the box. The control allocation works with acceleration inputs. However the video above is running the mc attitude controller, which assumes that your acceleration should be always along the body z axis.
Details please
You can find the details in the video description
Your the guy who answered every questions about PX4! I'm a beginner at PX4 and your posts are great help to me.
Each moment I see your post, I fill fammiliar with your Korean style name. But not sure that your Korean.
Very cool! Is the graphical representation of the waves also in usv_gazebo_plugin?
Nice!
Thanks!
small question, how u modeling the cable in gazebo?
Hi just one question: how u using mavros to landing ? coz it has to keep sending mavlink command, how I control it landing and disarm it ??
I am working on flipping the drone using Ardupilot, any ideas. If possible can we have chat in discord?
Could you show me how you wrote the mavros node in the vedio?
The instructions are in docs.px4.io/master/en/simulation/multi_vehicle_simulation_gazebo.html

Hello @Jaeyoung Lim. I am trying to set a communication link between a RPi and a Pixhawk and I found MAVROS to be a possibility. My idea is then to perform obstacle avoidance in offboard mode. Do you think MAVROS is a good solution? Thank you in advance
yeap
Do you have a small example about how to use mavros VTOL plugin to control drone via ROS C++ code (you had written) in Gazebo environment ? I have checked the official MAVROS github to find where is this VTOL plugin you have mentioned, but I couldn't find it. mavros/mavros/src/plugins/ github.com/mavlink/mavros/tree/master/mavros/src/plugins mavros/mavros_extras/src/plugins/ github.com/mavlink/mavros/tree/master/mavros_extras/src/plugins Note: The only information I was able to find are these: MAVSDK/src/plugins/action/action_impl.cpp github.com/mavlink/MAVSDK/blob/fe06d5bafd2fb2180b04c389d1773c56b7876c79/src/plugins/action/action_impl.cpp#L169-L256 Add vtol plugin for vtol transitions #1323 github.com/mavlink/mavros/pull/1323/files mavros/mavros_msgs/srv/ (/CommandVtolTransition.srv) github.com/mavlink/mavros/tree/master/mavros_msgs/srv

@@jaeyounglim Where can I find a small example that shows how to apply this VTOL plugin in mavros to make VTOL drone to change from "VTOL:Quad-Rotor" and "VTOL:Fixed Wing"? I couldn't understand how to apply it. I will be very glad if you would guide me @Jaeyoung Lim please, thank you very much.
@Jaeyoung Lim friend, I have opened x2 threads in "discuss.px4.io", so if it is possible would you check them please when you have time please? thank you very much. 1) How to change VTOL Flight Mode from Multi-Rotor to Fixed Wing in OFFBOARD mode by using ROS (MAVROS) in Gazebo too without using QgroundControl? thank you discuss.px4.io/t/how-to-change-vtol-flight-mode-from-multi-rotor-to-fixed-wing-in-offboard-mode-by-using-ros-mavros-in-gazebo-too-without-using-qgroundcontrol-thank-you/19787 2) How to change the speed/altitude/heading direction of VTOL from ROS ,and from pxh terminal with commander+param commands discuss.px4.io/t/how-to-change-the-speed-altitude-heading-direction-of-vtol-from-ros-and-from-pxh-terminal-with-commander-param-commands/19749
Typhoon H 480 is mounted with camera automatically, so how to add camera on iris to control quadrotor drone within px4 gazebo too? thank you.

How can we do setpoints for the drone/fixed wing by using ROS directly in Gazebo (instead of using QGroundControl)? Jaeyoung Lim friend, I will be very glad if you would guide me (I am a newbie but I want to learn these subjects), thank you very much.
You can use mavros: github.com/mavlink/mavros
When I click to change the flight mode to "offboard" from QGroundControl or when I type "commander mode offboard" from terminal, nothing happens which is same for manual or flight modes too which this only happens when I try to change flight mode manually. Do you know what might the cause of it be? thank you.

Yes, offboard mode is rejected if you are not streaming setpoints or the setpoints are invalid
