Do not fly

Hi, I bought two SteamVR V2 station and the lighthouse deck. I followed the tutorial https://www.youtube.com/watch?v=DCEHht72B08 , but when I tried to use the take off button nothing happened. I manually moved the drone and the system appeared to be working. I also tried to use the autonomous_sequen...

Re: Send pitch angle

Helo!

Thanks for the answer!

I was using the flow deck. I did the tests again, without any decks, and it really worked correctly.

I haven't studied the kalman filter yet, but could this behavior (with the flow deck) be related to the fact that there is no linear movement?

Re: Send pitch angle

Well, we did a few more investigations. First, we found one more strange thing. When we are not sending pitch commands the variable stabilizer.pitch seems to work as it should, but as soon as the engines turn on stabilizer.pitch it looks more like rate pitch. This is the exact code we used. # -*- co...

Send pitch angle

Hi, I'm trying to send the pitch angle setpoint to crazyflie 2 using python lib. It may seem like a naive question, but does the command send_setpoint (roll, pitch, yawrate, thrust) send the desired setpoint of the pitch angle? I modified example/ramp.py to send with send_setpoint(0, 10, 0, 20000) f...

Re: Receive rate pitch

I found the error.

It's time.sleep (0.1) on the penultimate line. It should be time.sleep (0.01).

Re: Receive rate pitch

Hi!

Thanks!!!

So, blue is the rate pitch we are sending, pitch in script.
The red is stateEstimateZ.ratePitch log.

The answer we get from crazyflie is completely different from the log. Every other log has a strange answer as well. :(

Receive rate pitch

Hello, I want to apply a tuning technique for pid parameters. For this, I need to send rate roll and rate pitch and receive the data used to calculate the input error of the PID controller. I'm using stabilizationModeRoll = RATE and stabilizationModePitch = RATE together with send_setpoint () to sen...
