Java Problem

Now if battery level is too low take off does not happen, but no error is given 
to user.
need to check battery level during take off attempt and switch to Error state 
immediately
if it is too low.

The current version only supports the "AfterGlow" controller. Attached is a 
patch for the SonyPS3Controller that enables support for the original SixAxis 
controller.

the video/vision enabled flags both return false even though info I receive 
through the control port 5559 says they are both true. I'm working with vision 
detect right now, and although it detects tags, I'm getting data like position 
is always (0, 0) and width in dimensions is always 0.

Often times I have to start the PS3Flight and ControlTower apps multiple times 
until the drone fully initializes. This happens mostly when the drone is 
accessed for the first time after it was powered up. Maybe the initialize 
command has to be sent repeatedly similar to the start and land commands?

Currently if controller is not connected, the following error is shown:

We should be able to work with AR.Drone 2 by initializing it to send video in 
old format.

What steps will reproduce the problem?
1. Support for the app in 34 bit mode.

What is the expected output? What do you see instead?
The application will not run die to errors. 

What version of the product are you using? On what operating system?
Macintosh 10.6.4 with java in 34 bit. 

Please provide any additional information below.

To save video stream to file we need to implement DroneVideoListener, writing 
frames as video file.

This will allow us to add capture functionality to UI.\

Create wiki page describing default keyboard and PS3 controller key mapping in 
ControlTower.
Include picture of PS3 controller with annotations.

Please make project build for Android.

It would be nice to have public maven repository for javadrone API.

Can we host it at google code? If not we can do it at codeminders.com web 
server in US.

What steps will reproduce the problem?
1. Create ARDrone object.
2. Invoke connect() and waitForReady().
3. invoke disconnect()
4. wait a bit
5. invoke connect()

What is the expected output? What do you see instead?
An IOException for Address already in use is received.

What version of the product are you using? On what operating system?
1.1 Mac OS X 10.6.7

Please provide any additional information below.
The problem can be corrected with two changes to the NavDataReader and 
VideoReader classes.
1. Set the channel socket to reuse addresses:  invoke setReuseAddress(true) on 
the socket before binding.
2. Modify the run method to invoke disconnect after the while(!done) loop 
terminates (not just in the if(done) statement).

See changes marked GWB in attached file.

We need to provide 32 bit mac DLL. Current DLL is 64 bit.

Maximize window.
See screenshot.

Attached are the files of my ControlTower application with a VideoPanel that 
displays battery, wind, ultrasonic and emergency warning icons. It also sports 
a configuration window for the drone control settings. Maybe useful for 
somebody. Goes into com.codeminders.controltower package. The contained images 
are public domain as far as I could determine.

Screenshot:

Per documentation take off and landing commands needs to be sent repeatedly 
until corresponding status changes in NavData.

I already started working on this, please do not touch this part for now.

I got the TestH264DataDecoder class to get images from the 2.0, here is a 
modified version in case it helps anyone.  It isn't perfect, I think there is 
something strange about theH264 decoder that is being used but it is a start.

Do not loose usb connection when Android application is suspended (or moved to 
background process) 

Project ControllTower-Android

Currently the javadrone api has no support for the target data the drone 
delivers. This makes it impossible to create real AR applications with the API.

The API should include a listener for target data from the drone.

It would be nice to have a blinking red light while video recording is active.

In some cases drone is not reacting on takeoff or land actions. However 
application displays that drone state is connected 

Project: ControlTower-Android

In RC helicopters usually controlls are mapped differently from ControlTower. 
I suggest we adjust them to match RC helis:

Left joystick:

UP/Down - throttle
Left/Right - yaw

Right joystick:
Left/Righ - roll
Up/Donw - pitch

It is very close to what we have now, except left and right joysticks are 
reversed.

Switch to Maven build. Split eclipse projects to 2: JavaDrone, ContolTower

AR.Drone 2 sends information from additional sensors in Navdata packets. We 
should decode it.
YADrone project http://vsis-www.informatik.uni-hamburg.de/projects/yadrone/ 
which is based on our
code have done this decoding, so we can backport some of their changes (license 
permitting) back to us.

I would like to assign default keys in PS3 contollers:

SQUARE - take snapshot
CIRCLE - START/STOP video.

So new users have them set by default, but could reassign later. 


How can I do this?

Currently only VLIB video codec is supported. It would be great to add support 
for new, P264 codec.

If hid api native library not found, ControTower should start and be usable 
with keyboard.

What steps will reproduce the problem?
1. Turn on the drone, connect to it via the program
2. Change a limit ie. max tilt from 40 -> 5
3. Click apply
4. Take off

What is the expected output? What do you see instead?
The drone should not tilt as steeply, however it still tilts just as steep and 
due to this flips over a lot.

What version of the product are you using? On what operating system?
1.1 on Mac OSX 10.7

Please provide any additional information below.
I have been able to change the rotation speed limit however this is after 
multiple shutdowns of the drone and program.

The current video implementation uses unicast and does not allow reading the 
video while another application is controlling the drone and displaying the 
video. The attached file implements a multicast video reader for ardrone. Maybe 
its helpful for somebody.

Cheers,
Normen Hansen

We currently ship only mac and linux native libraries to work with 
GameController. I tried to build windows DLLs. They seems to find controller 
but could not read events from it.

This is the task where somebody who have PS3 controller and experienced in 
Windows programming could help.
Source code to build DLLs could be found http://code.google.com/p/javahidapi/

New DLLs need to be tested with ControllerTest java application which is part 
of javadrone project. It currently works well on Mac/Linux.

Current calculation of values of movement is quite rough and vanishes all 
advantages of PS3 controllers (or other controllers that have joysticks).

For instance, when you use PS3 controller with control treshold 0.3 and 
max_euler_angle=0.3, move values will always exceed max_euler_angle (due to 
control treshold), so drone will cut them down to 0.3 of its maximum angle. 
This will lead to the situation when your PS3 joystick has only 5 values: 
center, left, right, up and down; but normally you would have a range of values 
(actually, -128..+128) for the precise controlling of the drone.

I hope, I have fixed this wrong calculation in attached patch.

Display PS3 Controller image (example  
http://avgjoegeek.net/wp-content/uploads/2012/02/tactical_button_layout.jpg) 
with descriptions on its functions

The current NavData only contains the state flags, the attached patch enables 
float and int data like altiture, battery, pitch etc. in NavData.java

The KeyboardController only allows to start and land the drone.
The attached patch allows full control of the drone using the keyboard.

Control tower freezes when you out of WIFi range 

when you go back inside range no drone is not auto reconnected 

What steps will reproduce the problem?

1. Clone and Build javadrone and make sure that javadrone artifacts are 
installed in local Maven repository.

  NOTE: Build (mvn install) fails at first due to an unresolved dependency to the hidapi-1.0 jar artifact.
  Assuming that the cause of this issue is absence of a remote Maven repository for javadrone-related artifacts, this issue was overcome by manually copying the missing artifacts to my local Maven repository.

2. Create a minimal Maven project and add javadrone-api as a dependency of the 
newly created Maven project:

    <dependency>
        <groupId>com.codeminders</groupId>
        <artifactId>javadrone-api</artifactId>
        <version>1.2</version>
    </dependency>

3. Try to build the newly created project (step 2)

What is the expected output? What do you see instead?

It is expected that the dependency to javadrone-api-1.2 resolves, given the 
structure found in local Maven repository:

How can I? It just won't open but the Control Tower will. HELP!

Email me @ [email protected]

When window is resized video aspect ratio should be preserved, using 
letterboxng or pillarboxing, if necessary.

The video selection numbers are shifted by one, the attached patch for 
ARDrone.java fixes selecting the video channel.

What steps will reproduce the problem?
1. load project into eclipse on a ubuntu 10.4 64bit system
2. add external jar's 
3. configure library path by exporting LD_LIBRARY_PATH or java 
-Djava.library.path=... in run configurations the path to libhidapi-jni-64.so
4. run the control tower app.

What is the expected output? What do you see instead?

- both methods from point three yield the same result. The library should have 
been detected. 


My machine specs:

-ubuntu 10.4 64bit
-java-1.6 (jdk,jre) - latest version

At the moment one has to know the int and string values of the animations and 
config options.

Attached is a patch for ARDrone.java that exposes enums that can be used to 
identify the desired
animation using code.
