2016-10-02 01:26:40 -0500 asked a question RVIZ and PTAM

Hello, if I move my drone at a static position and I rotate it in the yaw angle, the system is thinking the drone is moving and he sets it to a new position. But the position is still the same, just the angle is changed. I am using PTAM for a localization and RVIZ for visualize the changes of the drone movements. At RVIZ the map is initialized with "world" and i get transformations by ptam_visualizer.

ROS Indigo Ubuntu 14.04

2016-09-19 11:42:58 -0500 answered a question Connecting Bebop drone with ROS

I solved the problem by myself. Upgrading the SDK ( in bebop_autonomy under the hood are the steps for it ). Its difficult, because there is no new revision key. You have change the hash in generate.py to master/xml + chance the xml-tags at the end ( ardrone3.xml and Command.xml ) and in url-mustache its not libARCommands , its arsdk-xml and chance Xml to xml. Then delete ALL .xml in all filenames and in the files ! After chance in ardrone3_setting_callbacks.h pilotingsettingsstate_maxdistance_value to .._current, the both circling_xx_values with current to and something like bankedterm value to STATE. After you can catkin the workspace.

the next prob is, that the driver is dying, cause the new frames are to big. So give the frames more space in bebop_decode.cpp

Now you can communicate with the drone.

Its about the ARSTREAM2_H264 . Its sending do driver and he is killing the driver..

I also can start with a nodelet. but i still get the same dying process

In my opinion its about the new drone firmware 3.9.0. There are 3 new videosettings and the drone is sending to ros and he cant handle it

2016-09-17 22:56:26 -0500 commented answer Connecting Bebop drone with ROS

I followed the introductions at bebop_autonomy. I catkined the package , connecting to bebops wifi and start with roslaunch bebop_driver bebop_node.launch.

2016-09-17 15:11:08 -0500 asked a question Connecting Bebop drone with ROS

Hey,

i want to control my Bebop2 with ROS messages. I downloaded bebop_autonomy and catkin it. When I want to run the launch file, the driver is getting killed

There is no log file and I actually dont know, why I cant compile it.

I have:

  • ROS Indigo
  • Ubuntu 14.04
  • Drone Firmware 3.9

Someone else had this problem? Is there another solution to use the drone with ROS?

hey guys, i wanna do a communication between windows (software) and ubuntu (ROS) with ROS.NET .

On windows is a software and it needs some images i create with rosnodes and a robot at ubuntu. i found, that I can write a program in C# and do a communication with ROS.NET . There are nodes publish and subscribe. Did someone already did it or could give me some introduction i could follow?

Hey guys, i am trying to use PTAM for my AR Drone. After i tracked my workspace, i want to save this pointcloud and reopen it at rviz. But i dont know how :/ i found out, that i have to use ptam_visualizer for publishing and dynamic_reconfigure as the GUI ( http://wiki.ros.org/ptam/ptam_visualizer ). Could someone help me please? I am a newbie in ros :/

2016-07-22 10:03:41 -0500 asked a question tum_simulator flightplan

Hey there, i am using the tum_simulator for ros indigo. I can simulate a drone and with standart_msgs i can fly around. Now i wanna use a flightplan. I found, that you can pub a node to autoflight/start to a realdrone. someone made it for simulated drone? i tried:

rostopic pub --once ardrone/start std_msgs/String "data"

"data" also must be on real drone. i tried to load it from the roscd.
