Hi,
Sorry for the late answering, I did not receive the notification that usually is made when someone replies a trend, I will take into account the recommendations that you gave me, thank you

Hi, I know that in order to flow deck to work properly, it needs a very texture rich surface, with my team, we are designing a mat ourselves (because we couldn't get one with the desired measures), but I am uncertain if it is suitable for the flow deck to work well, I attach here a .pdf with the ima...

Hi,
I will try again when they give me again the authorization to be in the lab, the last time I was there I could record a video of the CF flying, here it is: https://photos.app.goo.gl/opH5vjJyYJYS5FRz6.

Hi again,
Here is the graph of the CF on top of a chair, the real height is around 0.6 meters, which is ok, the second graph is when I moved the CF to the ground, and the last one with the CF on ground after a few seconds.

Hi, I'm sorry I didn't give any updates yesterday, I couldn't get to the lab because of traffic law restrictions in my city, however, today I will be there. What could be a safe distance between the CFs? The controller is Mellinger, when running the ROS master it says "Using Mellinger controlle...

The CF in the video that I uploaded was in TDoA 2 instead of TWR that was a mistake I made, also it didn't have the flow deck, when I set it in TWR mode, it did the job well. For multiple CFs I use TDoA 2 as required, but I do not know why it bec...
