Hamish Willee 88d623bedb Move PX4 Guide source into /docs (#24490) 
* Add vitepress tree

* Update existing workflows so they dont trigger on changes in the docs path

* Add nojekyll, package.json, LICENCE etc

* Add crowdin docs upload/download scripts

* Add docs flaw checker workflows

* Used docs prefix for docs workflows

* Crowdin obvious fixes

* ci: docs move to self hosted runner

runs on a beefy server for faster builds

Signed-off-by: Ramon Roche <mrpollo@gmail.com>

* ci: update runners

Signed-off-by: Ramon Roche <mrpollo@gmail.com>

* Add docs/en

* Add docs assets and scripts

* Fix up editlinks to point to PX4 sources

* Download just the translations that are supported

* Add translation sources for zh, uk, ko

* Update latest tranlsation and uorb graphs

* update vitepress to latest

Симуляція кількох рухомих засобів з Gazebo

This topic explains how to simulate multiple UAV vehicles using Gazebo (Gz) and SITL.

:::info Multi-Vehicle Simulation with Gazebo is only supported on Linux. :::

У Gazebo дуже легко налаштувати сценарії з кількома рухомими засобами (у порівнянні з іншими симуляторами).

Спочатку зберіть код PX4 SITL:

make px4_sitl

Each instance of PX4 can then be launched in its own terminal, specifying a unique instance number and its desired combination of environment variables:

ARGS ./build/px4_sitl_default/bin/px4 [-i <instance>]
  • <instance>: The instance number of the vehicle.
    • Кожен рухомий засіб повинен мати унікальний номер екземпляру. Якщо він не вказаний, номер екземпляру за замовчуванням - нуль.
    • When used with PX4_SIM_MODEL, Gazebo will automatically pick a unique model name in the form ${PX4_SIM_MODEL}_instance.
  • ARGS: A list of environmental variables, as described in Gazebo Simulation > Usage/Configuration Options.

Це дозволяє підвищити гнучкість та адаптивність.

Кілька рухомих засобів з ROS 2 та Gazebo

Multiple vehicles with ROS 2 are possible.

  • First follow the installation instructions for Gazebo.

  • Then configure your system for ROS 2 / PX4 operations.

  • В різних терміналах вручну запустіть симуляцію декількох рухомих засобів. Цей приклад відтворює 2 квадрокоптери X500 та літак з фіксованим крилом aFPX:

    PX4_SYS_AUTOSTART=4001 PX4_SIM_MODEL=gz_x500 ./build/px4_sitl_default/bin/px4 -i 1

    PX4_SYS_AUTOSTART=4001 PX4_GZ_MODEL_POSE="0,1" PX4_SIM_MODEL=gz_x500 ./build/px4_sitl_default/bin/px4 -i 2

    PX4_SYS_AUTOSTART=4003 PX4_GZ_MODEL_POSE="0,2" PX4_SIM_MODEL=gz_rc_cessna ./build/px4_sitl_default/bin/px4 -i 3

  • Запустіть агента:

    MicroXRCEAgent udp4 -p 8888

    Агент автоматично з'єднається з усіма клієнтами.

  • Run ros2 topic list to see the topic list, which should look like this:
