Hi,

Please, could you explain how the position and velocity setpoint are converted to roll, pitch and thrust?

Thank you.

Hi Kimberly, Thank you for your reply. I am using the local positioning system to do my flight experiments. My controller has the global position, velocity and acceleration as input and the output is a desired global acceleration. In that case, I will convert the desired global acceleration to the d...

Hi,

I have developed an algorithm to compute the desired acceleration for crazyflie. What is the best way to convert this acceleration to desired roll pitch and thrust so I can use the send_setpoint to command the crazyflie to track the desired acceleration?

Thank you.

Best regards,

Hi, Thank you for your reply. So, if I wanna increase the TX power in Crazyflie and recompile with the config.mk, should I use the command make cload or make clean? Also, in what circumstance do I need to increase the TX power in Crazyflie? Flying with TDoA2 mode or TDoA3 mode or both? Best, Yu-Hsiang

Hi arnaud, Thank you for your reply. It did solve the permission problem. However, I still faced some issues. 1. When I select the configuration, it shows that EEEPROM configuration changed, restart for it to take effect. What does it mean by restart? Does it mean that I just need to press the reset...

Hi, I updated the LPS node to the latest firmware and the LPS worked properly in TDoA2 mode. And now I am trying to access to the node low level configuration to force the TX power but facing some issues. 1. I tried to open the node low level configuration via VM. However, it showed permission denie...

Hi,

Thank you.
When will this change be available?

May I ask why the initial x is set to be 1.5 here?

https://github.com/bitcraze/crazyflie-f ... ore.c#L140

Also, the parameter of the stabilizer.estimator is 2.
I have attached a flow deck on the Crazyflie.

Hi, When I connect to the Crazyflie2.1, the initial state x is not zero! I have tried to restart the Crazyflie and connect to the pc client. However, the initial state estimation of x is not zero every time. I also checked the parameter, it shows 1.5 in kalman.initial x. The firmware of the Crazyfli...
