The room is bright (artifical light), and the floor is a patterned carpet. The strange part to me is that this occurs within 10-15 minutes of it working normally - under the same lighting conditions, same carpet, and it can have both styles of behaviour (though it usually does work; perhaps 18-19 ti...

It takes off, then moves in one direction (say, forward) until we stop the program (we test in a confined space, so there is not much room to let it roam around). We control it using the MotionCommander interface & flow deck; this happens in the absence of a control input. I.e., we tell it to ta...

Sometimes when Crazyflie takes off, it starts to drift to one side, instead of hovering in one spot. It seems to be resolved after a power cycle or two, but it's still worrisome that it happens. For reference, we are using the flow deck, and this issue has been observed even happens when the battery...

In the MotionCommander interface, there are the following lines of code: def _reset_position_estimator(self): self._cf.param.set_value('kalman.resetEstimation', '1') time.sleep(0.1) self._cf.param.set_value('kalman.resetEstimation', '0') time.sleep(2) What are the reasons for resetting the position ...

We found that the yaw angle would continuously increase - however, when we raised the Crazyflie several inches above the ground, the estimates were consistent with the movement. I assume this is due to the flow deck being able to provide more relevant information (initially there was only a piece of...

Using logging, I can see the yaw angle provided through the stabilizer log data - before the Crazyflie takes off, the yaw angle is not constant after it is moved. After the Crazyflie is rotated slightly, the reported yaw angle continuously increases (or decreases). Once the drone takes off, the angl...

I am trying to control the Crazyflie via the Python client over the CrazyRadio, but I find that open loop control does not lead to satisfactory performance. In particular, I am interested in attitude control, and the ability to maintain a constant position (I don't need it to be able to move to a gi...
