There are three sensors, namely, horizontal camera, vertical camera, and an ultrasound, modeled in the simulation environment. I could not find any IMU being modeled as a sensor on the bebop2 in Sphinx. Using the official SDK one can access these values by setting the appropriate callback.
ARCOMMANDS_Decoder_SetARDrone3PilotingStatePositionChangedCallback ARCOMMANDS_Decoder_SetARDrone3PilotingStateSpeedChangedCallback ARCOMMANDS_Decoder_SetARDrone3PilotingStateAttitudeChangedCallback
I was wondering how these values are calculated in the simulation environment.
