Re: Vicon Control of CF 2.0
All, I am trying to change the coordinate system to left hand system from what I initially used. I have a major question. What is the order of transformation that has been adopted ? Is the transformation matrix, R(from body to inertial frame) = Rz(yaw) x Ry(pitch) x Rx(roll) I mean is the order ZYX ...

Re: Vicon Control of CF 2.0
Marcus, Thank you for replying. I will check by using the new orientation you mentioned. I will try some more time to perfect my solution- if that fails I shall try adapting to the other two alternate projects. I doubt I am doing a mistake with the PID tuning. I start my PID tuning assuming that the...

Vicon Control of CF 2.0
I am trying to control the Crazy Flie using Vicon camera system. I have markers set on the CF to read its X,Y,Z and yaw angles. I am then using a PID position control loop to feedback new values of pitch, roll, yawrate and thrust pwm to the CF to either maintain its position or follow a trajectory. ...

Moment of Inertia of CF 2.0
I am trying to modify the code to include closed-feedback control. I would like to simulate my code first in MATLAB before I test it on the quad. However, I need the Ixx, Iyy and Izz value of the code to simulate its dynamics in MATLAB. Did anyone find this value before or did the developers already...

Re: Code for Individual motor control
I have looked at those codes but still don't understand how the values we give are translated to something which the code understands. Can you pin-point the exact part of these programs I should look ?

Code for Individual motor control
I understand that we can give the thrust desired, roll desired, pith desired and yaw desired. The firmware has code so that it will control the individual motors so that the IMU tries to reads the desired values and the barometer reads a height value (corresponding to the thrust). But My question is...

Control of the coreless motors of CF 2.0 by ESC or PWM signa
Does the CF 2.0 have any ESC to control the coreless motors on it or is there any other method ?

Getting Started with development on CF 2.0
I just purchased the CF 2.0 and can fly it off using the PC client and iOS. However, I would like to do some development and add additional sensors. I went through the wiki page and different posts and found numerous threads that explain differently. Some advice to use the VM and then they also talk...
