Robo-emoto

ROBO EMPOTO is a very curious and emotion robot. While in fact useless by nature, ROBO is destined 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 first step is to assemble the chassis, which include wheels, motors and the body of chassis.

Connect the parts according to the diagram in the picture

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();

}

there are in total 3 custom made lcd faces for the robo emoto. A happy face, a poker face and a sad face. In order to achieve this, we need to make a few custom characters as well as using some of the built in characters as shown in the image

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 ultrasonic sensor. once it is too close, it stops its motors, turns around, and continues to move forward.

Now watch it go!
