can I send attitude control command through crazyradio?

Hi, I have used crazyflie2.1 and bigquad to build a bigger drone, and now, I want to use ROS to control crazyflie 2.1 to make some specific actions and posture, I know I can use ros and motion capture system and crazyradio to send position command to get the drone to a point in space, I wonder if I ...

Re: How to turn the propeller without attitude information from the sensor?

If you want them to start at the same time you can set the m1,m2... values first end then enable them. If you want to see an example you can check the health.c that runs the propeller test. Thank you And I mean I want to control a certain motor or certain motors individually, instead of simply test...

Re: How to turn the propeller without attitude information from the sensor?

I am not sure what you mean by "sensor data", do you mean logging values using the log subsystem? I will try to answer your questions: 1) there are a couple of parameters that allows to control the motors directly. "motorPowerSet.enable" can be set to 1 to enable the individual ...

How to turn the propeller without attitude information from the sensor?

I used the crazyflie2.1 and bigquad to creat a bigger drone,and the drone has a shell that looks like a sphere. now I want to let it roll on the ground,but I think if I use the sensor data when I'm controlling the propeller,I can't get it to "roll",and it might fly straight into the air. S...

Re: BigQuad used but the drone is very unstable

Hi, The Kalman filter no longer needs the weight/thrust so nothing to do there. What might need tuning is the different position controllers. If you are using the PID (which is a good start) you should alter the BaseThrust here . The other PID position parameters should work but could also be tuned...

Re: BigQuad used but the drone is very unstable

We are still lacking a tuning guide :oops: Some pointers you can find in this post. There are tuns of guides on the internet though which might be a good start. Generally a bigquad/bolt will be more powerful so start by reducing RATE P,I and D by half end test. You can use the parameter framework t...

BigQuad used but the drone is very unstable

Hello! I tried to use the BigQuad to build a bigger drone,and now, I successfully assembled a bigger drone. when I didn't install the propeller,I tried to connect the drone to the client,and use the remote control to control it ,I sent some commands through the remote control, but the drone shaked v...

By the way, can I use Betafight's firmware in Crazyflie?

Thank you!
