I am having some issues with the ARDrone Parrot 2.0 and hope someone else may be running into the same thing.
While hovering, the drone is (seemingly) randomly losing altitude then recovering . It is doing so while not being commanded any velocity inputs and should hold altitude.
We are using the drivers from the ardrone_autonomy (dev_unstable branch) on github. We are able to watch the PWM outputs being sent to the motor and they are dropping from the hover command do a small value before exponentially returning to the hover value when this drop occurs.
The issue could be a communication between the IMU and the onboard controller or on our software control implementation.
Has anyone seen a similar problem or suggestions to test/troubleshoot what is happening?
