2014-01-29 04:46:15 -0500 asked a question tum_ardrone - Waiting for first navdata to determine drone version

Hi,

I downloaded and was able to compile tum_ardrone on Ubuntu Linux 12.04. I'm using ROS Hydro.

I'm able to use the keyboard to fly the ardrone - but I cannot get video for PTAM. The PTAM Video window does not even show. PTAM Drone Map View shows, and the console for state_estimation shows this all the time.

"Waiting for first navdata to determine drone version"

Under tum_ardroneGUI, I can see under Node Communication Status that the Drone Navdata is 0Hz.

when running ardrone_autonomy ardrone_driver, i get

Tag 34866 is an unknown navdata option tag

One option (0) is not a valid option because its size is zero

*[Navdata] Checksum failed : 989 (distant) / 35945 (local) *

Any idea what could it be? Who is supposed to send navdata?

Thanks, appreciate if anyone could help!

Have you installed and compiled TooN on your computer?

Install TooN : git clone git clone git://github.com/edrosten/TooN.git This will create a TooN directory wherever you cloned it to. Navigate to the TooN directory and type :

./configure

make

make install

Have you tried installing liblapack-dev ? If you are using ubuntu you can do this :

Install Synaptic Package Manager from Ubuntu Software Center. From Synaptic Package Manager, search for the following packages : liblapack-dev libblas-dev

Add them to install

2014-01-26 21:41:04 -0500 asked a question Setting up ROS, where to put environment variable?

Hi,

Where should I place the following in Ubuntu 12.04? export ROS_PACKAGE_PATH=~/catkin_ws:$ROS_PACKAGE_PATH

I want to launch this everytime so that I can just use roscd beginner_tutorials everytime.

Thanks.
