Flight controllers for quadcopters and other drones are incredible pieces of engineering. Not only do these boards keep an aircraft level, they do so while keeping the drone in one place, or reading a GPS sensor and flying it from waypoint to waypoint. The PXFmini controller and autopilot shield is the latest project from Erle Robotics that puts eight servo outputs on the Pi, barometer and IMU sensors, a power supply, and all the adapters to turn the Raspberry Pi Zero into a capable flight controller.
This makes for some interesting applications we can only imagine now. The schematics for the PXFmini are open source in the best traditions of the RC and drone community and will be available soon. You can check out a video of the FXPmini flying around an office below. If you use a APM2 it even exposes mavlink on a uart where you can control everything about the autopilot from the Pi.
There seems to be some large, unmarked chip on the side of male angled pins; they mention ability to run Dronecode autopilot so my bet is on some STM32 as slave doing most dirty work. I know what you are talking about, but not everyone on this board knows the truth. Erle should keep up the good work, and there are bigger fish down the road for Erle that is not for everyone on this board. The chrt command is an option.
Have a look at github. You have a very real problem, though, if the kernel crashes. An embedded mcu with a proper watchdog is far less likely to lock up in the first place, and can quickly recover if it does. SO images provided by Erle Robotics are customized, the kernel is modified with the real time patches to give priority to the autopilot.
Nowadays there are companies like google or Intel pushing really hard to the real-time kernel. Also APM is really strong about Linux autopilot.
IMO this is what sells this project. This is why I mentioned mavlink. Gives you access to all the functions of a already well developed flight controller. Looking at the board, I suspect they probably based it on the Naze32. As someone else pointed out, it looks a lot like an STM32 processor on their board. Considering the STM32F is a 72Mhz device with minimum of 20k ram and 64k flash it would have no trouble handling the basic stability functions etc.
Pretty much everything can be controlled over mavlink, everything from raw stick input to handing it GPS coordinates to fly to.

Our hope is that we can use the I2C bus on the Naze 32 to send data to the Raspberry Pi, then allowing for a small window where the Pi can interject a flight instruction directly into the writeMotors call that will allow it to make decisions about flight control. Which option would work best?
If we added a new task, how would the tasks share memory and how would we manage 'stale' commands? AdamCanadyI think this is the wrong approach. Cleanflight already supports the concept of a configurator or a "ground station" which can change Cleanfight settings but also can control the motors. This ground station can be attached via usb but also via Bluetooth. The Cleanflight configurator is the obvious example you will note that you can control the motors from within the configuratorand EZ-GUI is another example.
This is an app running on Android communication with and controlling the quadcopter using the MSP protocol over a Bluetooth link. My approach would be to do something similar on the Raspberry Pi - get the MSP protocol going, probably initially over a serial link, and then later over a Bluetooth link if you want.

What would be very interesting is to see if the vehicle could be programmed to perform these same flight instruction against a relative position instead of a fixed one… for example… do a figure 8 flight path where the intersection of the 8 is 1 meter above my head. Now if i walk or move the vehicle would continue to do the figure 8 but it would move the flight path to correspond with the moving position of my head.
I too thought something similar. So the foundation is there. More to come hopefully! Accepting essential orders - here's how. Get the only spam-free daily newsletter about wearables, running a "maker business", electronic tips and more! Subscribe at AdafruitDaily. Paul Boudreau.

This quadcopter has a particularity because he's using 2 differents controller and he could be pilot with 2 differents devices : a remote control or a smartphone.
A Quadcopter Controlled By A Pi Zero
The Multiwii controller look after the 4 motors and distribute the power to supply them whereas the Raspberry Pi collect the informations who came from the smartphone and relay them to the Multiwii. You can also take pictures and Full HD video too!!! A Pi camera is places on the frontground of the Drone Pi. It ca recording or just take a picture to a USB key. The frame of this quadcopter is constituating with different recycled elements and it was another challenge : create a quadcopter with sometimes heavy elements But we did it!
We are some young french students and it was our first creation. We were helping during this project with some internet website whose Instructables and now we want to share with you our Drone Pi.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. You have to weld the connectors to the ESC wire, to the motors wire and to the distribution board wire. Multiwii is a open source french project who was based on a arduino. The project is open source so we can find many kind of multiwii.
This is a flight controller: Its role is to send speed signals to the esc to hold the quadcopter in the air. We use the mutlwii project beacause its a known project used by many users with a great community but mostly because programs like this is too complicated for us.
In our project the raspberry made the main role. First at the startup it create a private wifi network with a DHCP server to give IP addressthis wifi network has no internet access and this only to communicate with the smartphone. Secondly it stat a python program created by us who start a websocket.
A websocket is a permanent connexion between the server raspberry and the client the smartphone appit will serv to received command from the app. Then the same progam connects to the multiwii via USB. It will serve to send commands informations who come from the smartphone to the multiwii see schema for understand.

The Naze is also matched up with some of the nicest GUI programs. Also features to get the most out of your configuration. This is an amazing flight controller for a multirotor. All the revision 6 boards include a built-in black box flight data recorder which is great. However, the Full version includes Mbit onboard SPI flash so this just means you can store more flight logs on your full board.
