Hello,

I've made a proof of concept of a voice controlled UAV using a Parrot Bebop 2. Voice recognition is done in a Raspberry Pi 3 thanks to Snips.ai it is done offline, you do not need internet.

Here is a small demo :

As you can see there is about 3 second between order and action, so don't fly near obstacles !

Maybe it could help disable people to fly UAV and experiment FPV. If you find it useful let me know.

A largest use case for vocal assistant in UAV could be to talk to Mission Planner to query information about battery or altitude.

More details on my github.

Hello, I just want to share with you my experience of using a 250 quad to take picture in holiday trip.

(after removing fisheye effect)

A 250 quad racer could be useful not only for racing. Thanks to is small size you could bring it with you in holiday to take pictures.

Everything you need fit in a quite small box :
- TX
- Quad
- FPV Goggle
- Video receiver
- Spare batteries
- Battery Charger

- Toolbox

It doesn't take more place than a DSLR and it lens. So I leave the DSLR at home and took the quad :-)
No gimbal but still useful.
I use a Runcam v2 as camera and the result is quite good. I admit it doesn't compete with DSLR for quality but you get another point of view !

I use a FPV camera pointing up to have a good view in forward flight and the Runcam pointing down. A good addition will be a video switch to be able to select the desired view in flight.

You have to keep safety first and do not fly over/near people, nor near airport. And of course respect the local law if exist.

Anyone having some the same and can give some advice ?

PS : coming back home with nice pictures increase the Woman Acceptance Factor ;-)

I had this idea in mind for a long time now, and when I heard about the Mimic from Freefly, I decided to do it for real. This is also part of some small projects I did about all the ways you can connect an Arduino to your radio transmitter to extend his capabilities.
So let's start with the Mimic, you can see here in action:

Connection

The only one difficult point here is that the Arduino Mini does not have SDA and SCL connectors, which are required for the I2C communication with the MPU6050. So you have to solder them by yourself.
 
Here is the cabling:

 
The Power and PPM signal are not visible here, for simplification purpose.
- the Power is 5V, depending on your Arduino Mini.
- The PPM signal is on the connector 3.
 

 

Source Code

 
The source code is a basic merge from Jeff Rowberg i2cdevlib code for the MPU6050 and the one from Hasi on RC Groups about the PPM signal.
 
I had put my sources on Github : diymimic.ino.
Feel free to improve it, it is just a quick and dirty proof of concept. Use at your own risk !
 
Let's try it !
 
Note : You have to wait a few seconds for the auto-calibration.
Here is the result, fisrt with a gimbal and second with a quadcopter !
