2012 - CS308 Course Project
Project website : e-yantra.org
It is developed as a Embedded and Real Time Systems course project at Indian Institute of Technology (IIT Bombay)
The aim of our project is to build a completely remotely controlled Firebird using the power of Android. What we have choosen to demonstrate is this project.
Android mobile processes the video stream (received via Wi-Fi) captured by the IP camera mounted on Firebird V bot, detects the presence or absence of TT ball and sends appropriate signal to the bot via Bluetooth. The bot then analyses the signal received and acts accordingly.

- Tennis Ball Collector using ATmega 2560 Robot
- Controlling Firebird V using an Android based phone via Bluetooth Controlling FirebirdV ATmega2560
- Embedded C
- JAVA
- Android
- Bluetooth
- Gripper
- OpenCV
- Setup the as shown in Hardware manual
- Install /bin/RemoteTennisBallCollector.apk in your mobile
- Burn the firebird/defult/Tennisball.hex onto firebird
- Connect both IPCamera and mobile to same Wi-Fi network
- Start the Application
- Enjoy!
- root folder of the project/ ** jni/ ** libs/ ** res/ ** src/ ** AndroidManifest.xml ** default.properties ** ... other files ... where
- the src folder contains Java code of the application,
- the res folder contains resources of the application (images, xml files describing UI layout , etc),
- the libs folder will contain native libraries after successful build,
- and the jni folder contains C/C++ application source code and NDK’s build scripts Android.mk
and Application.mk. These scripts control the C++ build process (they are written in Makefile language).
Also the root folder should contain the following files - AndroidManifest.xml file presents essential information about application to the Android system
(name of the Application, name of main application’s package, components of the application, required permissions, etc)
It can be created using Eclipse wizard or android tool from Android SDK - default.properties is a text file containing information about target Android platform and other build details. This file is generated by Eclipse or can be created with android tool from Android SDK
- src\com\eyantra\android\tennisball ** BallCollectorActivity.java - main class which does all control actions ** Bluetooth.java - Bluetooth communciation module ** DeviceListActivity - List the dveices for bluetooth ** OpenCV - OpenCV Java wrapper for C++ files in jni/ folder ** ReloadImageView - Class to reload images at regular interval (not used)
- res/ ** layout/ - main layout ** drawable/ - images and sub-layouts used ** *values/strings.xml - Strings used in code
- jni/ ** cvjni.cpp - contains C++ Open CV functions to be used in other places ** cv/ and cvcore/ - opencv library files
- Tennisball.c - firebird controller actions. Receives signal from Bluetooth and acts accordingly.
Use the Hardware and Software Setup manuals for complete set of instructions.
- AVR Studio
- Open CV for Android Environment setup
** Refer: http://opencv.itseez.com/doc/tutorials/introduction/android_binary_package/android_binary_package.html
** Download NVPACK
** Download OpenCV
** Start the Eclipse and choose your workspace location.
** Configure your ADT plugin
** Import OpenCV and samples into workspace. - Setup C++ OpenCV Environment setup
** http://opencv.itseez.com/doc/tutorials/introduction/android_binary_package/android_binary_package_using_with_NDK.html#android-binary-package-with-ndk
** Download Android NDK
** Follow all instructions for Eclipse Setup
By this time all your sample files should be working perfectly fine - Download the example files
** http://www.stanford.edu/~zxwang/android_opencv.html
** Download opencv files and put them in jni folder of your android application root directory
You are ready to go!!
- Google it!
- Refer the Hardware setup manual complete set of instructions.
- Android+OpenCV
