Steps:

• Identify Interfaces & classes from LeJOS
• Implement a prototype
• Implement a stable solution
• Develop tests
• Move toLeJOS commons the missing interfaces & classes
• Review on internet the majority of Use cases from Users
• Review how to include the concept aboutBrickPi

Motivation:

Many users use the library to build software for robots inMindstorms ecosystem, but in order to go further with the idea to have robots based on multiple bricks, it is necessary to implement the concept aboutLocalEV3.

In LeJOS ecosystem, LocalEV3 is a recent concept appeared in EV3:
http://www.lejos.org/ev3/docs/lejos/hardware/ev3/LocalEV3.html

Note: If you are going to use only one Brick, you could use directly the objects that you need to use in your program, but if you are going to use Remote capabilities, RemoveEV3 is necessary. In order to begin that journey, it is necessary to provide aLocalEV3 support.

Some examples usingLocalEV3

Brickbrick =BrickFinder.getLocal();Audiosound =brick.getAudio();sound.systemSound(0);RegulatedMotorleft =newEV3LargeRegulatedMotor(brick.getPort("B"));RegulatedMotorright =newEV3LargeRegulatedMotor(brick.getPort("C"));// get a port instancePortport =LocalEV3.get().getPort("S2");// Get an instance of the Ultrasonic EV3 sensorEV3UltrasonicSensorsensor =newEV3UltrasonicSensor(port);GraphicsLCDg =LocalEV3.get ().GetGraphicsLCD ();BrickInfo[]bricks =BrickFinder.discover();for(BrickInfoinfo:bricks) {Brickbrick =newRemoteEV3(info.getIPAddress());brick.getAudio().systemSound(0);}
