Re: [Paparazzi-devel] Feasability of ardrone with paparazzi for surveillance

[Felix Ruess]

Hi,

reliability of the ARDrone is not great, mostly due to some bugs in the firmware of the navboard that we have no control over.

There are some heuristics in the Paparazzi code that gets navdata packets from the board to try to filter out erroneous or switched magnetometer and sonar data, but as it is just a heuristic it's not 100% reliable.

Nothing we can really do about this...

The Bebop should be much more reliable as it doesn't have a navboard with closed firmware on it anymore and all sensors are directly accessible (by Paparazzi).

Hope that helps,

Felix

Hi Thomas, Robert,

Regarding the ARDrone, while what Kirk says is true, we never managed to get the ARDrone 2 to fly reliably outdoors. This is because the interface with the magnetometer was very troublesome. I think the guys at ENAC had more luck with this though. We only use the ARDrone for experiments where there is no need for a magnetometer.

Regarding the rolling spider, we worked on this in the past and there is a wiki page about this: http://wiki.paparazziuav.org/wiki/Rolling_Spider . It might be a bit outdated though.

Ewoud
