Hello, maybe it is a “stupid” question but I want to be sure about this: what do m1…m4 represent in the motorpower log data?
Speed in rpm? Or a integer number proportional
To that?
Thanks

This is not a trick, it is an implementation of the Crazyflie Log protocol: the packet that contains the log block period encodes the period as a 8bit unsigned interger in 10ms steps. So for example if you ask for a period of 150ms, the packet sent to the Crazyflie will contain a period of 15 which...

Hi, 1) Yes, on the protocol side sampling time is expressed in multiple of 10ms so the minimum achievable logging period is 10ms. 2) If you need faster logs you can easily hack it by removing the *10 where log block is started in the firmware: https://github.com/bitcraze/crazyflie-firmware/blob/39d...

Hello everyone, i was wondering if it possible to exploit the mellinger controller directly with the methods defined in the commander.py class defined here https://github.com/bitcraze/crazyflie-lib-python/blob/master/cflib/crazyflie/commander.py Like in the position hl commander library where it is ...

Secondly, about your question with the LPS system together of the flow-deck. They should work together, as long if you are flying as low as the bottom range sensor still can measure something. But it might be good to keep an eye on this github issue, which is discussing the same thing https://githu...

Hi Gianni, Let us first discuss the case with only the LPS system and the drift you are experiencing: Is the crazyflie's front pointing in the right direction, like in https://www.bitcraze.io/getting-started-with-assisted-flight-position-hold/? The LPS system is not able to read the heading of the ...

Hello everyone, i am running into some curious behaviours of my crazyflie when i use the LPS and the flowdeck. If i use only the flowdeck and exploit the commander libraries (send_hover_setpoint...for example) everything works fine If i use only the LPS system without the flow deck, the client ident...

Hello, I have some questions: i'm building a protected cage in order to fly my crazyflies safely. I have to buy a tatami carpet to make crazyflie fly also with the flowdeck (not only loco position system). Do you have any suggestion on wich color and pattern help the flowdeck to perform better? In t...

HEllo, i have one question. Does the Kalman filter works on the firmware even without the LPS and only the flow deck is connected? Or there is another estimator running when LPS is not available? I'm asking this because on Raffaello D'Andrea's paper is clearly written: "The estimator presented ...

Thanks
