This package contains the implementation of a gazebo simulator for the Ardrone 2.0 and has been written by Hongrong Huang and Juergen Sturm of the Computer Vision Group at the Technical University of Munich. This package is based on the ROS package tu-darmstadt-ros-pkg by Johannes Meyer and Stefan Kohlbrecher and the Ardrone simulator which is provided by Matthias Nieuwenhuisen. The simulator can simulate both the AR.Drone 1.0 and 2.0, the default parameters however are optimized for the AR.Drone 2.0 by now. You can fine more details on my report. The simulator is on the simulator_gazebo platform. Before using this simulator, it is recommended to get know more about the simulator by reading gazebo tutorials. Additionaly, you can get more information about flying robots and AR.Drone from the lecture visual navigation for flying robots. Real quadrocopter structure: The AR.Drone2.0 connects with a computer via WIFI, while the user manipulate a joystick which is via USB connecting with the same computer.

ROS is running in this computer. Simulated quadrocopter manipulation: After the simulation is started. The user can use a joystick to manipulate the simulated quadrocopter. The botton functions of the joystick are the same as manipulating the real AR.Drone2.0. The following video shows an experiment about how the simulator works compared to the real AR. gazebo, ground_truth_to_tf, robot_state_publisher: The simulator program. rviz: A 3d visualization environment for the simulated flying robots. joy_node, ardrone_joystick: They are the joystick driver and the command information translator for the Ardrone. Your computer should have ROS and simulator gazebo package installed. The ROS version should be fuerte and the Gazebo version of the ROS plugin (which is, for fuerte, 1.0.2). Be sure that rviz is also installed. 1. Install the following additional required packages in your ROS workspace. ardrone_autonomy package: This is the official driver for the real Ardrone flying robots. 2. Install tum_simulator package:

You can start the simulator with one of the following flying scenario: You can manipulate the quadrocopter with joysticks after launching: For observation you can use following commands: OR using the rviz tool.black ops 2 utiliser drone If you get the following error message when you start the simulator, you should close all the other nodes which connect the simulator by some ROS topices. ar drone parrot preçoAnd try again to launch the simulator file. parrot ar drone essaiFurtherm more, you can terminate your ROS master, even close all your terminal windows and restart the simulator again.parrot ar drone preisvergleich

- installing Gazebo 1.6.0 is not required (though its dependency libbullet might be), since launching gazebo via ROS will always use the Gazebo version of the ROS plugin (which is, for fuerte, 1.0.2) - Gazebo (and, by extension, the TUM simulator) is very picky about the installed graphics card; parrot ar drone pspas far as we can tell at this time, only Nvidia cards really work (and only with the restricted Nvidia driver), ATI/AMD and Intel cards will not work, since the drivers do not have all the OpenGL/FireGL capabilities that Gazebo requires. parrot ar drone chicagoIn case of ATI drivers, we observed error messages about missing GL features, but with the Intel drivers, Gazebo simply segfaults (or rather, the Intel driver segfaults and Gazebo quits without any meaningful error message). Because of the limitation of the gazebo simulator, not all the AD.

Drone sensors are 100% modeled in the simulation. Compared to the real AD.Drone ardrone_autonomy driver, the simulation can also send as the real AD.Drone with the same names: The navigation data /ardrone/navdata includes many information. The following sensors are implemented in the simulation: We release our code under the BSD license. However, as we strongly build upon Gazebo and HectorSLAM, corresponding licenses apply as well. > or Jürgen Sturm .Having your Parrot drone parts in great condition is essential for the best flying experience and to avoid crashes. This article with drone repair videos show you how to inspect and replace your Parrot AR drone parts. Inspecting your Parrot AR drone parts every couple of days will keep your quadcopter flying perfectly. By checking parts such as cogs, shafts and blades to make sure they aren’t bent, cracked or broken, will help ensure your quadcopters operates at it’s best. The below videos cover everything from checking and maintaining your AR drone, to replacing parts such as the mainboard, navigation board and central cross which have become broken.  

At the very end of this article, we also have some good information on how to fix ultrasound emergency errors on your Parrot AR drone. The Parrot AR is a terrific drone.  It’s fast, acrobatic and fun to fly.  It is also one of the most d-i-y friendly drone on the market.  Every part is easily replaceable.  The Parrot AR has probably been the best selling drone of all time. I hope this article and videos are of great assistance so you can quickly get back to having some great flying fun. How To Replace Your Parrot Drone Parts Maintain And Replace Gear, Shaft and C-Clips Parts This video shows you how to check, inspect, lubricate and replace cogs, pins, shafts, new blades and clips on your Parrot AR.  This is a  thorough video giving you loads of information to maintain and replace your Parrot AR parts. Replace Central Cross Parrot Drone Part This is a detailed video on how to remove and then replace a broken Parrot AR Central Cross.  It takes approximately 2 hours .  

The video shows what tools and parts you need and then takes you step-by-step on how to remove the parts and then install the new AR drone central cross part. Replace Mainboard Parrot Drone Part Watch the below drone video and follow the 11 steps to successfully replace you AR Drone Mainboard part. Remove the motherboard cover screws Remove the motherboard cover Remove the motherboard screws Unplug the motherboard battery cable Unplug the 2 motherboard data cables Mount the new motherboard Plug back in the 2 motherboard data cables Fix the new motherboard screws Plug back in the motherboard battery cable Replace the motherboard cover Final Step : Fix the motherboard cover screws Replace Parrot Drone Parts – Navigation Board Here is how to replace a damaged navigation board.  He certainly makes it look easy.   Watch the below video and follow these 7 steps. Remove the motherboard ( in video 2 above) Remove the  navigation board support

Remove the damaged navigation board Mount the new AR drone navigation board Replace the navigation board support Replace the AR drone motherboard Fix the motherboard screw Parrot AR Ultrasound Emergency TroubleshootingIf your drone experiences an “Ultrasound Emergency” error on screen or your drone seems to fall from the sky uncontrollably or doesn’t seem to know distance from the ground. Ultrasound measures the distance from the ground so if you are getting this error, you should bring your drone in to land pretty quickly.  If the ultrasound isn’t working at all, you won’t be able to take off. So you can try the following to fix the ultrasound emergency error.  Be careful and handle all the parts gently when you open your drone; Before opening your parrot, check to see if you have the latest firmware for you Parrot AR. If not then update to the latest version. Open up the Parrot AR and check all cables to make sure they are correctly seated and that none of the cables are work or damaged.  

Make sure all cables are tight and replace and worn or damaged cables. After you have checked all the cables check and blow away and dust etc inside the parts.  Dust causes static electrical interference. Examine the cover over the 2 ultrasound sensors.  The sensors may not be lined up perfectly or the cover may be hampering the sensor.  I have seen where one Parrot owner was able to fix the ultrasound error by simply cutting part of the plastic off. Just about 1 inch of the end so the cover is not anywhere near the ultrasound sensors. Check the connection to the pressure sensor. Peel off the plastic bottom and take a look at the navigation to mainboard connections.  Remove the three connection points and remove the navigation board.  Next, check the pressure sensor (it’s the black square with a bit of foam visible on the top) on the top side of the board. This may not be stuck on correctly.  Peel it off and stick the black pressure sensor to the board. You many have a faulty transducer.
