Robot "Number42" building steps, presented at JavaOne4Kids Robo4j.io framework has beed used for robot control logic
![Develop and Deploy demo1 and demo2:
- Downloading template:
Download of the zip 鍖le and unzip to the desired folder: https://goo.gl/WG7DrB
The download should begin automatically, if it does not then go to the link and download it
manually: https://github.com/mirage22/robo4j-javaone-hand-one
- After downloading
In the project folder i.e. the folder where you extracted the zip 鍖le from above src/main/
java/com/javaone/number42/ open 鍖le Number42Robot.java
- link with our favourite IDE
We need to link Robo4j library robo4j-brick-alfa-0.2.jar with opened project. Library is in
the project folder libs/
- COMPILE and UPLOAD Number42
a) Compile
Open command line / command prompt and run Robo4j-Center:
$java -jar robo4j-center-alfa-0.2.jar compile
Project will compile into the same folder into the 鍖le Robo4jNumber42.jar
b) Upload
Open command line / command prompt and go to Project directory and run Robo4j-Center
$java -jar robo4j-center-alfa-0.2.jar upload <host> <user> <password> <path>
example:
$java -jar robo4j-center-alfa-0.2.jar upload 10.0.1.1 root password /home/root/lejos/samples
Demo 1: Activate LCD and Front-Hand active of the robot Number42
Open Project 鍖le Number42Robot.java and write following code to initiate front-hand and sensor
CODE:
public static void main(String[] args) {
RobotNumber42 robot = new RobotNumber42();
RobotTouchSensor robotHandTouchSensor = new RobotTouchSensor("S4");
RobotMotor robotHandMotor = new RobotMotor("A");
robot.setHandMotor(robotHandMotor);
robot.setHandSensor(robotHandTouchSensor);
robot.setHandRelation(new RobotHandRelation(robotHandTouchSensor,robotHandMotor));
robot.setLCD(new RobotLCD(HandONE));
robot.setPAD(new RobotPAD());
robot.build();
if(robot.check()){
robot.activate();
}

CONTROL Demo:
- by pressing touch sensor you can control robot hand
- To exit demo press EXIT button on the BRICK
Demo 2: Make Number42 alive - activate the platform
Open Project 鍖le Number42Robot.java and write following code to initiate front-hand and sensor
CODE:
public static void main(String[] args) {
RobotNumber42 robot = new RobotNumber42();
RobotTouchSensor robotHandTouchSensor = new RobotTouchSensor("S4");
RobotMotor robotHandMotor = new RobotMotor("A");
RobotMotor robotLeftMotor = new RobotMotor("B");
RobotMotor robotRightMotor = new RobotMotor("C");
robot.setHandMotor(robotHandMotor);
robot.setHandSensor(robotHandTouchSensor);
robot.setHandRelation(new RobotHandRelation(robotHandTouchSensor,robotHandMotor));
robot.setMotorLeft(robotLeftMotor);
robot.setMotorRight(robotRightMotor);
robot.setPlatformRelation(new RobotPlatformRelation(robotLeftMotor, robotRightMotor));
robot.setLCD(new RobotLCD(Number42 FULL"));
robot.setPAD(new RobotPAD());
robot.build();
if(robot.check()){
robot.activate();
}
}

CONTROL Demo:
1. Similar behaviour like Demo1
2. By using Brick PAD you can move robot forward/backward, left/right
3. To exit demo press EXIT button on the BRICK](https://image.slidesharecdn.com/20160914javaone4kidspresentaitonnumber42isalive-160925163555/85/JavaOne-presentation-building-steps-Number42-is-alive-33-320.jpg)

- 34. Run Robo4j-joystick and play instructions: a) Go to project ROOT directory b) Write command: $java -jar robo4j-joystick-alfa-0.2.jar c) Robo4j-joystick will be open for you Robo4j-Joystick control steps: 1) Connect Joystick with Robot Number42 setup robot IP address and press connect
- 35. 2) move BLACK point in any direction Every segment of the joystick represents speed of the robot. The segment speed can be changed but there is a secure mechanism. This secure mechanism does not allow to set extremely high speed values. In such case the value will be change back to the default. Exceptions: 1) Trying to connect to the wrong IP
- 36. Robo4j Brick Client services: Lego Brick Client is program running on the lego brick. Lego brick default IP address 10.0.1.1 Lego brick client default port: 8025 available services HTTP GET: 1. http://10.0.1.1:8025/setup 2. http://10.0.1.1:8025/status 3. http://10.0.1.1:8025/exit 1. service setup provides information how sensors and engines are connected to the brick 2. service status provides information about the command that has been processed but the Robot.
- 37. 3. servie exit service exit turn off all running services (agents) on the Lego Brick and it ends the running program available services HTTP POST: Robo4j Brick client also provides POST service. The POST service allows to send batch of command in JSON format
