How to read the kalman estimated position and use it in the code
Hello everybody i'm starting to understand better how the CF work and students here in L'Aquila also seem to appreciate labs with these drones. I want to do a further step forward trying to understand how to read sensor data (particularly position estimation or z value from the flow deck). I want to...

Re: Flow deck suggestions
Hum, what does happen? With the flow it should 'work'. Actually I just tried with this sequence: sequence = [ (0, 0, 0.15, 0), (0, 0, 0.3, 0), (0.5, 0, 0.3, 0), (0.5, 0.5, 0.3, 0), (0, 0.5, 0.3, 0), (0, 0, 0.3, 0), ] Takeoff is an issue, I get it to take-off right about 3 times in 5, I added a step...

Re: Flow deck suggestions
With the flow, the kalman filter will still keep track of and output an absolute position that you can use, though this absolute position will drift over time. The amount of drift should be very small in good conditions but there is no way to know the precision. If you want to recalibrate the absol...

Re: Flow deck suggestions
VX and VY are velocity in the body referential. yaw_rate is the rate at witch the yaw is turning in degree per second. So if you set VX to 0.5 and have a positive yaw_rate the Crazyflie will go forward turning right. If you keep the yaw_rate at 0, you can send "move 0.5m/s on X and 1m/s on Y&q...

Re: Flow deck suggestions
vx and vy are the speeds along the x and y axis right? I'm looking for something like "move 1 meter along x and 2 meters along y"
The yaw rate is the yaw angle right?

Flow deck suggestions
Hello everybody i just received my flow deck and i'm really excited about that. It works very good. I had a look at the examples and i saw that the only main function that is used to move the drove is the function commander.send_hover_setpoint. It's clear how to use it but my question is: Is there a...

Crazyflie can't calibrate
Hello...again i have one crazyflie drone that has a strange issue: it starts regularly but the red led that should blink each second after the calibration, actually blinks each 2 seconds. As it can't initialize properly. Within the client i can connect with the crazyradio PA but i can't see any outp...

Re: Where to put the file config.mk
You need to put the config.mk file in the same folder, in tools/make. For all modification you need to "make clean" to make sure you a building all the files with the new config. If you have an of-the-shelf Z-Ranger deck you do not need to modify anything though. Just make sure you have t...

Where to put the file config.mk
Hello, again another newbie question. I'm sorry about that :D I'm enabling the zrange so i downloaded the config.mk file but i'm not sure that by putting it in the same folder of the makefile file works. I checked also this topic https://forum.bitcraze.io/viewtopic.php?f=6&t=2563&p=12975&...
