Where should I go next? Is there any ROS package or stack that can be used as a tutorial/sample to use ardrone_autonomy?Here are some examples: “falkor_ardrone” is a ROS package which uses the “ardrone_autonomy” package to implement autonomous control functionality on an AR. State Estimation, Autopilot and GUI for ardrone. This ROS stack includes a series of very basic nodes to show users how to develop applications that use the ardrone_autonomy drivers for the AR drone 1.0 and 2.0 quadrotor robot. This repository contains the source-code for the Up and flying with the AR. AR Drone simulation in Gazebo, compatible with . How can I report a bug, submit patches or ask for a feature? offers a nice and convenient issue tracking and social coding platform, it can be used for bug reports and pull/feature request. This is the preferred method. You can also contact the author directly. Why the has been patched? The ARDrone 2.0.1 SDK has been patched to 1) Enable the lib only build 2) Make its command line parsing compatible with ROS and 3) To fix its weird function issue.

The patched SDK is being hosted on an external repository. Why the wifi bandwidth usage is too much? The driver has been configured by default to use the maximum bandwidth allowed to ensure the best quality video stream possible (please take a look at default values in parameters section). That is why the picture quality received from Drone 2.0 using this driver is far better than what you usually get using other software. If for any reason you prefer the lower quality* video stream, change , and parameters to the default values mentioned in the AR-Drone developer guide. Please note that lower quality does not mean lower resolution. By configuring AR-Drone to use bitrate control with limits, the picture gets blurry when there is a movement. What is the default configuration for the front camera video stream? How can I calibrate the ardrone front/bottom camera? It is easy to calibrate both cameras using ROS Camera Calibration. First, run the camera_calibration node with appropriate arguments: (For the bottom camera, replace front with bottom)

After successful calibration, press the button in the UI. ar drone miru mod gpsThe driver will receive the data from the camera calibration node, then will save the information by default in . ar drone 2 dicksmithFrom this point on, whenever you run the driver on the same computer this file will be loaded automatically by the driver and its information will be published to appropriate topic. parrot ar drone aanbiedingSample calibration files for AR-Drone 2.0’s cameras are provided in folder. Can I control multiple drones using a single PC? or can I make my drone connect to a wireless router? Since version 1.4, the driver supports connecting to multiple AR-Drones from a single PC. Thanks to efforts and patches provided by @kbogert. For more information please check this wiki page.

Is there any support for GPS (Parrot Flight Recorder) Yes but it is experimental. The code is maintained in a separate branch (gps-waypoint).

Knowing how to calibrate the Phantom 4 IMU is important.  If your Phantom 4 is flying erratically or is not flying correctly to your touch, then your best option is to fly the drone in and calibrate the IMU. When the IMU is back in the green and within the ideal range, then it is safe to fly the Phantom 4 quadcopter again. It must be noted that the Phantom 4 and Phantom 4 Pro IMU are calibrated differently.  I have the IMU calibration procedure for both Phantom 4 and the Pro model below. With the Phantom 4, you should not move the drone while doing the calibration.  With the Phantom 4 Pro model, you place the drone in various positions during the calibration process. The Phantom 4 Pro calibration is half way down this article so you can skip down there if you have this model. Read the Phantom 4 IMU calibration instructions a few times and watch the below videos.  Then it will be very easy for you. You can also print the instructions just in case you need to do an IMU calibration while out having a great adventure with your Phantom 4.

Remember, in some circumstances you may need to calibrate the Phantom 4 IMU a few times to get it right within range. What Is The IMU – Answered The IMU (Inertial Measurement Unit) is a critical component in your drone.  If it is not working correctly, then there is a very good chance that you will crash your drone. An inertial measurement unit works by detecting the current rate of acceleration using one or more accelerometers. The IMU detects changes in rotational attributes like pitch, roll and yaw using one or more gyroscopes.  Some IMU include a magnetometer, mostly to assist calibration against orientation drift. A computer continually calculates the quadcopters current position. First, it integrates the sensed acceleration, together with an estimate of gravity, to calculate the current velocity. Then it integrates the velocity to calculate the current position. You can read further in this informative article entitled “Drone Gyro Stabilization, IMU And Flight Controllers Explained“.

DJI Phantom 4 / 4 Pro App Note: The Phantom 4 uses the DJI Go App whereas the new DJI Phantom 4 Pro uses the DJI GO 4 App. Phantom 4 With Dual IMU & Dual Gyroscope The DJI Phantom 4  has in fact 2 X Inertial Measurement Units.  This gives the Phantom 4 real flight stability and also redundancy in case of failure. In the DJI Go App, these are listed as IMU1 and IMU2 in the calibration page of the DJI Go app.  Both Phantom 4 IMU are calibrated at the same time. Ideal IMU Accelerometer and Gyroscope Range For the Accelerometers, you should be at around the 0.0003 for ACC1  and ACC2.  The Gyroscope GYRO 1 and 2 should also be around the 0.0002 or 0.0003 mark. If your Accelerometers and Gyroscope are around the 0.0006, you can easily reduce this down to 0.0003 with an IMU calibration. Phantom 4 IMU Calibration Procedure Choose a very flat surface for the Phantom 4 IMU calibration (very important) Remove the propellers before you start the compass calibration

Have your batteries fully charged in the Phantom 4 quadcopter, the Remote Control and your tablet of smart cellphone Next, start up the Phantom 4 Remote Controller Start the DJI Go App Start up the Phantom 4 quadcopter In the DJI Go App, click on the “Camera” settings Up in the left hand corner, click on the little quadcopter (attitude) button which is the main settings page Scroll down and click on the “Advanced Settings” Click on “IMU Calibration” Click on “Start Calibrating” A popup message will appear saying “Calibration Requires Approximately 5 Minutes.  Do Not Move Aircraft During Calibration” Click Ok and the IMU calibration will start Then next page will show you the IMU calibration progress.  Stay on this page during the Phantom 4 IMU calibration. The Phantom 4 has dual Inertial Measurement Units which will be calibrated at the same time When the calibration reaches 100%, a popup message will appear stating “Calibration Complete.

Power down and then restart the Phantom 4 to complete the calibration process You will need to power down the Phantom 4 again and then put back on the propellers After the IMU calibration, it is also a very good idea to calibrate the gimbal and also to calibrate the Phantom 4 compass. How To Calibrate the Phantom 4 Gimbal In the DJI Go App, click on the “Gimbal Settings” icon Then click on “Gimbal Auto Calibration”. Click “ok” on the popup message Next you will see a gimbal calibration process The gimbal on the Phantom 4 will move around during the process When it reaches 100%, you will get a “Gimbal Calibrated” message on screen Notes on Phantom 4 IMU Calibration Calibrate on a very flat surface Make sure to do the IMU calibration away from electro magnetic objects Remove propellers before starting Batteries should be at least half charged but better if they are fully charged In the Sensors Page in the DJI Go App, the Accelerometers and Gyroscope should be showing green

You may need to do the IMU calibration more than once if they are still outside the above ideal ranges Calibrate the gimbal after the IMU calibration Calibrate the compass outside following the successful IMU calibration Here is a terrific video showing you how easy it is to calibrate the IMU on the Phantom 4. How To Calibrate the Phantom 4 Pro IMU The procedure to calibrate the Phantom 4 Pro is slightly different than the Phantom 4.  With the Pro, you will move the quadcopter into various positions to calibrate the IMU. It is still quite and easy step.  Read the below instructions a couple of times and watch the below video. The Phantom 4 Pro uses the DJI Go 4 App.  Here is the Phantom 4 IMU calibration procedure. Choose a very flat surface for the Phantom 4 Pro IMU calibration (extremely important) Have your batteries fully charged in the Phantom 4 Pro quadcopter, the Remote Control and you tablet of smart cellphone First, start up the Phantom 4 Pro Remote Controller

Start the DJI Go 4 App Next, start up the Phantom 4 quadcopter In the DJI Go 4 App, click on “Go Fly” Click on the three dots in the top right hand corner to go into the “General Settings” Click on the little quadcopter button at the top of the screen The next screen shows you the dual IMU and dual Gyroscopes Click on “Calibrate IMU” Click on “Start Calibrating” and follow the onscreen prompts.  This is where the Phantom 4 and Pro models are different In the bottom right you will see 1/6 so there are 6 steps to calibrate the IMU on the Phantom 4 Pro The first step 1/6, you don’t need to do anything. On the second step 2/6, you need to put your Phantom 4 Pro on its side as it shows on screen In step 3/6, you need to put the quadcopter on it’s other side Step 4/6, place the Phantom 4 Pro with it’s nose pointing down Step 5/6, place the quadcopter with is nose pointing up In the final step 6/6, place the Phantom 4 Pro upside down
