Re: Camera issue with crazyflie-ar-detector
Even with the highest shutter speed possible, I had still some motion blur (and I needed sooo much light)! It's because my camera was really crappy. Now with the PS3 EYE it's better but I still need a lot of light so it's pretty difficult to setup everything each time I want to use it. As Arnaud sai...

Re: Situation Awareness - Free Fall Prevention
Happy to ear that!
Could you explain (very quickly) what was the reason of the watchdog issue?
I'll try that as soon as I get my hands back on a crazyflie!
Unfortunately It won't be this week.

Re: Situation Awareness - Free Fall Prevention
When you compile the firmware, use the "Make Debug" link. If I remember well, it should skip some testing.
I'm glad to ear that the ground effect is positive !

Re: Situation Awareness - Free Fall Prevention
Quick reply : Maybe you can try to build the firmware on debug mode. Apparently it can solve this type of issue if it's not because of your code. Worth the try ! One question : do you "initialize" the ground altitude? Because the barometer gives you the altitude at sea level. Maybe you'll ...

Re: Enabling Altitude Hold
It's true that althold would be a huge improvement for mobile phone since flying the crazyflie with them is really hard. But since the packet used to send set-points is about to change, it would be better to wait and then modify the apps. Because at this time, the way althold is handled in the pytho...

Re: Camera issue with crazyflie-ar-detector
I finally bought the PS3 camera and well, it's really better than my previous webcam! It's quite hard to configure the camera and you have to do it again each time want to use it because of the different light. But at the end I was able to make the crazyflie hover autonomously and keep its position ...

Re: Enabling Altitude Hold
You're welcome, enjoy the flight! ;) Altough, if you find that the althold mode is not quite stable (like huge drop or rise etc), you can try to put a piece of foam under the crazyflie in order to cover the barometer. It seems to improve the values measured by the barometer (less "wind" ef...

Hi Konstantin,
I'm a bit busy this week, but I'll answer to you this week-end or at the beginning of next week!

Re: Setpoint explanation
Take a look at the code used on the kinect project. In control folder you'll find kctrl.py.
It's this file who send the setpoints according to the actual position of the crazyflie and the desired position. It uses several PIDs in order to control each value (yaw pitch roll thrust).

Re: Setpoint explanation
Basically, the setpoint contains (roll, pitch, yaw, thrust). (Take a look here ) Roll and pitch are in degrees, yaw is in degree per second and finally thrust is a value between 0 and 65535. There are two different methods for autonomous flight : - the older one uses a kinect or a webcam. In this me...
