The plugin mechanism is currently used to provide support for sensors, the camera, RFID, and the Media, Extras, and Portfolio palettes. A plugin has been [http://lists.sugarlabs.org/archive/iaep/2011-March/012715.html developed for WeDo] [http://tonyforster.blogspot.com/2012/01/wedo-plugin-for-turtle-art.html (and here)] and additional plugins are being developed for Arduino, NXT, and GoGo.

'''NOTE''': As of Version 193, it is necessary to use a set of refactored plugins. These will be posted to the wiki ASAP.
===How to install a plugin===
===How to install a plugin===
Plugins are typically distributed as a *.tar.gz archive
Plugins are typically distributed as a *.tar.gz archive.
In versions 137+, there is a built-in method for installing plugins from Turtle Art itself:
# Download the plugin to your Sugar Journal, a USB key, or $HOME/Documents.
# Click on the 'Load plugin' button found on the Activity toolbar.
# Select the plugin downloaded in Step 1.
# Go to the Palette toolbar to confirm that the plugin has installed and loaded properly.
In early versions of Turtle Art, please follow these instructions:

Note that you should not need root access to install plugins into your home directory.
Note that you should not need root access to install plugins into your home directory.
===How to uninstall a plugin===
Your plugin is installed in a subdirectory of
/home/olpc/Activities/TurtleArt.activity/plugins
In Terminal or Gnome, delete that subdirectory. You may need to make the Activities directory writeable first, in Terminal type
chmod 777 /home/olpc/Activities

Andrés Aguirre is part of the Butiá team in Montevideo:
:We have released the 1.0 version of the sources, which has full integration with tortugarte (http://www.fing.edu.uy/inco/proyectos/butia/publicaciones.html). Last month we gave away nearly 30 Butiá robots in a robotic event organized by the University. These robots were given to secondary schools throughout the country, in this event we gave some tutorials and exercises to do with our help. One of the schools made a great line follower in tortugarte ;) : http://www.youtube.com/watch?v=Szp0LWLyPIg Then on the second day we give some tutorials and some children really enjoyed the experience, like Pedro a 10 year old child who really has programming skills! http://www.flickr.com/photos/butiarobot/5059177334/ http://www.youtube.com/aguirrea#p/u/7/p0y11iyhFko
:In future months we will go to the schools where we give the robots to continue teaching and giving new challenges. If you would like to see more about Butiá, we have a flickr site: http://www.flickr.com/photos/butiarobot/ and also a web page: http://www.fing.edu.uy/inco/proyectos/butia

This plugin uses the camera and get the position of an object of a color.

The plugin add this palette:
The plugin add this palette:
[[File:turtleart-followme-palette2.png|800px]]
[[File:turtleart-followme-palette2.png|1050px]]
Examples:
=====Examples=====
The "classic" use: on "Start", use the "Calibrate" block to open a window that shows the camera output. In the center of that window there is red square. The FollowMe Plugin uses an algorithm that obtains the "promedial" color of the object in the square. The result of that algorithm is shown in a small square in the corner. When you consider that the color is a good "representation of the object", press any key, the window will close, and FollowMe will use this color. After calibration, you can use the "X position" and "Y position" blocks. The block "X position" is the "center" of the object seen by the camera along the "X" (horizontal) axis. This value is an integer between 0 and 320. When the object is not detected,the algorithm returns -1. The operation of the "Y position" block are the same, but returns the position respect the "Y" (vertical) axis. The value returned is between 0 and 240.

====Pattern detection====
Add a palette to enable pattern detection with the camera.
[[File:PatternDetectionPalette.png]]
Translation:
* "Viendo Señal": Pattern in sight
* "Distancia Señal" Pattern distance
This palette adds blocks to detect ARToolkit patterns and the distance to them. This plugin is an ARToolkit wrapper, and comes with several traffic signals already configured.
=====Examples=====
Here are some samples and videos on how to use the palette blocks.

* [http://tonyforster.blogspot.com/2012/01/arduino-and-xo-laptop.html The Freetronics Leostick]
The Arduino functionality was corrected from previous versions:
* Analog and digital reading now works correctly
* Auto detection of ttyUSBx port for FTDI device (Arduino board uses this for USB)
It requires the Firmata protocol to be uploaded to the Arduino board. (see [http://wiki.laptop.org/go/Arduino here])
Use the latest Firmata version (2.1 as of now) downloaded from the Firmata page (firmata.org)
The Firmata version included with the Arduino IDE has some inconsistencies.
This version has english and spanish translations.

This is just a first rough pass at a plugin do calculations on the nutritional value of different food types. The plugin itself comes with some sample foods: apples, bananas, cookies, and cake. It is expected that the food choices will be customized by deployment.
