kandi X-RAY | AirSim Summary
AirSim is a simulator for drones, cars and more, built on Unreal Engine (we now also have an experimental Unity release). It is open-source, cross platform, and supports software-in-the-loop simulation with popular flight controllers such as PX4 & ArduPilot and hardware-in-loop with PX4 for physically and visually realistic simulations. It is developed as an Unreal plugin that can simply be dropped into any Unreal environment. Similarly, we have an experimental release for a Unity plugin. Our goal is to develop AirSim as a platform for AI research to experiment with deep learning, computer vision and reinforcement learning algorithms for autonomous vehicles. For this purpose, AirSim also exposes APIs to retrieve data and control vehicles in a platform independent way.

QUESTION
I am using AirSim, and I need a hexacopter with Ardupilot based firmware. Documentation exists on how to do this with PX4, but not Ardupilot. How would I go about making this happen?
...ANSWER
Answered 2021-Jun-30 at 17:32Open your project in Visual Studio, navigate to Plugins/AirSim/AirLib/include/vehicles/multirotor/firmwares/arducopter/ArduCopterParams.hpp
Find the setupParams()
method, and replace setupFrameGenericQuad(params);
with setupFrameGenericHex(params);
And set your Ardupilot FRAME param to hexacopter (this can be done in QGroundControl)
QUESTION
I am using Microsoft AirSim with Unreal engine, and connecting with python API. I am using the LandscapeMountains project available through Unreal. I am able to capture the altitude with client.getGpsData().gnss.geo_point.altitude However the altitude does not seem to change if I set the drone on a straight flight path. Shouldn't it be changing with various mountain terrain?
Like when the drone flies over a high mountain shouldn't the altitude be closer to zero than when it passes the mountain. If this isn't the way it should work, how would I get the relative distance between drone and the terrain directly below the drone?
I hope someone reads this that uses AirSim.

will give you z axis position with respect to your player start position. Means your initial spawn position would be considered the origin and all other distances will be measured relatively. So, external objects like mountains etc won't affect the value.
If you want to get relative vertical position, you can read about altimeter here.
QUESTION
So I have a .py script that I am trying to run, and in either command prompt or anaconda prompt. If I run python filename.py
, it gives me this error:
python: can't open file 'C:\Users\tform\Documents\AirSim\CapstoneAPI.py': [Errno 2] No such file or directory
.
I am not sure how to solve this issue because the file is in that location. Do I need to mess around with some settings?
I am using Visual Studio 2019 as my IDE for python.
...ANSWER
Answered 2021-Feb-25 at 07:33As people said, when we use the command "python name.py
" in the terminal to run a python script, we need to enter the parent folder of this python file so that it can be found.
Solution: We could use "cd" to go to the parent folder of the python file: (Please go to your folder "AirSim".)
QUESTION
I am trying to install AirSim/Unity on MacOS Catalina. When I run Unity/build.sh I get a fatal error:
...ANSWER
Answered 2020-Mar-18 at 16:38You have told your library target to link against boost_filesystem
, but you did not convey in your CMake where to find the Boost header files.
The idiomatic way to find Boost using CMake is to use the configuration files that now ship with Boost (e.g. BoostConfig.cmake
), as of Boost version 1.70 and greater. You can make use of these by calling find_package(Boost ...)
, then linking with the imported target Boost::filesystem
