Re: Trajectory for crazyflie
Hi professor Hoenig: Thanks for your reply! I will have a try tomorrow!! I have already wrote a minimum snap ros node to generate a trajectory, which outputs position, velocity and acceleration.

(1)In the crazyflie-firmware/src/modules/src, I found the controller_mellinger.c, but when I use this controller, the cf flies very aggressive and crashed.This problem will disappear when using the PID contro...

Re: error:[crazyflie_server-1] process has died [pid 20730, exit code -6
Hi professor hoenig: I have tried this method just now, but it is no use....I can only solve this problem by using the official release of the cf firmware, but this can not support cf flying without flow deck. I notice one thing that when using the official release the ESTIMATOR is "complementa...
