Re: Low Level Control
I am using the app on Windows, is it possible to do it using that?

Re: Low Level Control
Hi, thanks for the reply, is it possible to show me how to modify the physicalConstant.h file mentioned on board since the firmware is uploaded as a zip file. Is it just find the file in the zip and change the constant? Am I allowed to do that? Thanks

Re: Low Level Control
Add on to that, is it possible to change the inertia tensor of the quadcopter like changing the mass constant you mentioned before?

Re: Low Level Control
Hi Arnaud, Thank you for your reply. I have been tuning the PID attitude and havent get a giid result yet. I will look into the PID rate later. For the state estimation, what is the accuracy for each one? I conducted an experiment of quadcopter hovering without the cage and my goal is to check the t...

Low Level Control
Hi, is there a possibility to control the quadcopter in a low level method, eg: 1. Outputing the rotor speed 2. Outputing the force and moment required. (I found something that control by desired force and angle. But I added on a cage and the quadcopter become really unstable)https://github.com/bitc...

Re: Data Logging
Hi Kimberley,
Can I ask how does the stateEstimate calculates the velocity?
I am applying a height PID controller on the crazyflie.
I am trying to print the height data of the quadcopter using the stateEstimate but it doesnt capture the disturbance I apply to the quadcopter

Re: Controller
Hi, thanks for the reply. How would the controller can be tuned to fix the change of the model considering if the model is changed, considering the moment equation for the quadcopter is M = I*wdot for linearised system. changing the model means it will change the I, how would changing the PID gain w...

Re: Controller
Is there any methods to control the quadcopter other than send_setpoint function. The quadcopter becomes unstable after adding a cage on it

Re: Controller
Besides, is the thrust parameters from stabilizer directly taken from the motor input or calculated by the acceleration of the quadcopter? I output a thrust of 65535 using send_setpoint, but when I logged the data at the same time, it only returns me thrust of 40k++
