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! |
2014-01-29 00:34:23 -0500 | answered a question | tum_ardrone 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 |
