Re: Crazyradio for Swarm using MOCAP and only the Lib

Hi Arnaud, Thanks very much for the advice, I changed the URI to use the same channel and data rate, but with a different address and it works very well, however if I add a fourth CF it moves randomly, I also tested by adding another radio and giving other channel to the CFs for that radio and it wo...

Crazyradio for Swarm using MOCAP and only the Lib

Hi, I'm trying to fly a swarm of CFs using a MOCAP system and only the crazyflie-lib-python, everything on Windows. I changed the mode for the CFs to Kalman and I modified the autonomousSequence.py script to support the communication between the CFs and the mocap by using the cf.extpos.send_extpos f...

Re: Autonomous flight and yaw

Hi Arnaud, I'm sorry about the time that has passed since you post this thread. I found that the real problem was the frame attached to the CF to track the balls in the mocap system. It influenced weight and balance I think. I removed the frame and attached only the little balls and it works very we...

Re: OpenCV hover-assist

Hi Arnaud, In the code that I’m using based on the autonomousSequence,py, there is a parameter called Kalman.resetEstimation which allows to reset the used data structures when it take-off as I can understand from the firmware (In fact I’ve been checking the firmware). As I described before I moved ...

Re: OpenCV hover-assist

Hi Arnaud,

Thanks by the reply, I just post a ticket as you suggested (https://github.com/bitcraze/crazyflie-f ... issues/203). I hope this issue can be solved and have a very stable cf. Thanks again.

Re: OpenCV hover-assist

Hi Arnaud, I’m using a motion capture system to track the positions of a crazyflie and using the function cf.extpos.send_extpos(x, y, z) as you described before. I compiled the crazyflie firmware with Kalman filter and I used cf.commander.send_setpoint(y_target, x_target,0, int(z_target * 1000)) for...
