MatMav: Matlab interface to monitor and command Pixhawk/PX4

Hi All,

Problem with 3DR telemetry when used by MATLAB serial communication function on Mac

Hi All,

How to send Motion Capture position feedback to Pixhawk?

Hi,

I am interested to send some high-level control commands to pixhawk using MAVLink, indoors. So, I have a motion capture system setup which gives accurate XYZ and orientation. I would like to tell pixhawk this information in order to use it onboard

[SOLVED] Battery volts drops significantly in short time!

Hi all,

I am not sure if this issue was reported before, but I could not find it.

I wanted to use Pixhawk on the Turnigy Integrated PCB Micro-Quad. I followed the following video for the parts and the assembly

Tool for Simulink-Xplane10 communication

Hi everyone.

Are you trying to test your control law, that you implemented in Simulink, on a flight simulator (e.g. X-Plane) and see how it  performs before you actually try it on your drone?

Then this is the right tool for you!!

This is basically some

Auto Center Line tracking during Auto Takeoff

Dear all,

I have been trying to implement a ground tracking code to use the front wheel to help keeping he plane at center line during the takeoff, and finally got it working! wohoo!

I am sure many of you who use fixed wings rc planes have faced this a

Need Help to Analyze flight data for More tunning (APM2.0): Log file attached

Dear all,

I would like to seek the experts' help, or who ever can help, to analyze my flight data in order to enhance the navigation performance in AUTO mode. 

I am using a bit older version of ArduPlane (2.4) and APM2.0, but it's doing well so far. Ho

Why Not to Include more Powerful Processor in Next Versions of APM

Hey all,

I was wondering why APM developers do not think of incorporating more powerful processing units on the next generations of APMs. The hardware's already received a lot of attention (including myself). 

Is it possible to do that, I don't see the

How to compute co-variance matrices of kalman filter for IMU+magnetometer

Dear folks,

I am developing EKF for attitude estimation, and,as you know, it's important to tune the covariance matrices for the process and the measurements.

Can any one help me to get the right parameters of these matrices, and how to do that experim

Communicating APM with MATLAB

Dear all,

I would like to communicate my APM2 with MATLAB using USB.

Basically, I would like to send the raw data of the accelerometer, gyros, and the magnetometer to MATLAB for advanced processing.

What is the right code to write on the APM as well as

Building a Kalman Filtering Frame Work for APM2: Using Matlab for Lab testing and an Embedded Computer (Gumstix) for Field Testing

Update: 5/5/2013

------------------------------

Done:

1- The MATLAB frame work is complete now

2- 7-state EKF is used for attitude estimation

3- the yaw correction is done using GPS course over ground

4- C-code is generated to work on the gumstix

5- impleme

In APM 2.0: How to get the magnetometer measurements logged?!

Hey folks,

Does any one know how to log the magnetometer in the flash card, in APM 2?

Thanks in advance
