Send specific altitude to the drone

[sulema]

Hi,

I am new in this, and I want to give a specific altitude to the drone, I read the libraries that manage the data of navigation but I can not find the answer yet. I think that I need to send data to the ultrasonic but, what do you suggest to me??

Thank you.

You can't do that with node-ar-drone alone. The only thing you can do is to provide a speed going up or down (just like someone pushing the throttle stick up or down). In order to maintain the altitude you need to add a control layer that observes the altitude navdata and perform adequate control (usually using a PID).

Have a look at https://github.com/eschnou/ardrone-autonomy, which do just that, and more, adding a simple control layer above node-ar-drone.
