MAV

Reason for forking

The library requires &'static string for connection, even though the underlying library tonic doesn't. This limits how one can specify connection url.

The Rust book for Drones

You can run the Rust book for drones by using mdbook:

mdbook serve

MAV-SDK

A MAVSDK gRPC client ( HTTP/2 ) for communicating with a drone, built from proto files using tonic.

You need to be running the MAVSDK Server (see https://github.com/mavlink/MAVSDK/releases) in order to use this crate.

Run PX4, Gazebo and MAVSDK Server with docker-compose

docker-compose up --detach

Take it to the skies

cargo run -p mav-sdk --example takeoff

Development

Prerequisite:

1. Make sure you have SSH key set for your Github account.

See Github articles:

• Generating a new SSH key and adding it to the ssh-agent
• Adding a new SSH key to your GitHub account

Building the project:

1. Clone the repository and change dir:

git clone git@github.com:AeroRust/mav.git && cd mav

2. Install protoc:

• For Linux & mac
• For Windows

3. Initialize the mavsdk-proto submodule:

git submodule init && git submodule update

4. Build the project

cargo build

Gazebo

Gazebo doesn't yet have built-in support for ArduPilot and it requires a plugin to be installed.
