This is the Python wrapper for MAVSDK.
The Python wrapper is based on a gRPC client communicating with the gRPC server written in C++. To use the Python wrapper the gRPC server called "backend" needs to be running on the same system. The wrapper is essentially auto-generated from the message definitions (proto files).
- Python 3.6+ is required (because the wrapper is based on asyncio).
- You may need to run
python, depending of your system defaults.
Install using pip from PyPy
To install mavsdk-python, simply run:
pip3 install mavsdk
The package contains
mavsdk_server already (previously called "backend"). It needs to be run manually with
start_mavlink(). Have a look at the examples to see it used in practice.
Run the examples
Once the package has been installed, the examples can be run:
Build and run from sources
Note: this is more involved and targetted to contributors.
Get the Python wrapper
Clone this repo and recursively update submodules:
git clone https://github.com/mavlink/MAVSDK-Python --recursive cd MAVSDK-Python
First install the protoc plugin (
cd proto/pb_plugins pip3 install -r requirements.txt pip3 install -e .
You can check that the plugin was installed with
$ which protoc-gen-dcsdk, as it should now be in the PATH.
Then go back to the root of the repo and install the dependencies of the SDK:
cd ../.. pip3 install -r requirements.txt -r requirements-dev.txt
Run the following helper script. It will generate the Python wrappers for each plugin. If the submodules are not initialized already, the script will take care of it.
Install the package locally
After generating the wrapper you can install a development (editable) version of the package using:
pip3 install -e .
MAVDSK-Python runs the
start_mavlink() is called. Under the hood, this will run
mavsdk/bin/mavsdk_server, which has to be built separately from MAVSDK and copied there.
