ROBO EMOTO

ROBO EMPOTO is a very curious and emotion robot. While in fact useless by nature, ROBO is destine for greater purpose of material manipulation.

1x Micro controller (Arduino Uno)

1x L293D DC Motor Drive Shield Stepper Motor Drive Shield

1x Half+ bread board

1x 16x2 row LCD screen

4x AA battery + case

4x DC motor

1x chasse

1x 1000k Potentiometer

1x Passive Buzzer

Many DuPont wires

The robot uses a passive buzzer connected to A3 on the motor shield.

CODE__

int buzzerPin = A3;

int maximum = 100;

int buzzDuration = 50;

void setup() {

pinMode(buzzerPin, OUTPUT);
}

void randSound(int maximum){

NewTone(buzzerPin, random(maximum, 10*maximum),buzzDuration); delay(maximum/10); noNewTone(buzzerPin);

}

void Loop () {

randSound();

}

Robo uses a 16x2 LCD screen to show its current mood. This is based on different "states" that are coded. When more than 20cm away from an object, he is happy. Get any closer and Robot Emoto gets very upset.

void sadFace() { lcd.setCursor(5,1); lcd.write((char) 3); lcd.setCursor(5,0); lcd.write((char) 1); lcd.setCursor(9,1); lcd.write((char) 201); lcd.setCursor(9,0); lcd.write(2); lcd.setCursor(6,0); lcd.write("x"); lcd.setCursor(8,0); lcd.write("x"); lcd.setCursor(7,1); lcd.write("o"); }

void loop() {

if (distance <= 25){

sadFace(); }

Using the same sensor as the buzzer and the LCD screen, ROBO continues to move forward until it is about to bump into and object. It does this through the readings of the ultra sonic sensor. once it is too close, it stops its motors, turns around, and continues to move forward.
