The following Robot is implemented using two LDR and ATmega16 microcontroller from ATMEL. The concept is same like Obstacle detector, the same robot can avoid obstacle in presence of enough light.

If you people are interested in AVR programming and robotics follow the following link on facebook.

Obstacle Detection and Avoider Robot using LDR-By Milan

This video shows an Obstacle Detector and Avoid-er implemented using ATmega16 and two LDR sensors.
This Robot can detect the obstacle in its path and take necessary move to avoid the obstacle according to the nature of obstacles. It is designed to work in Normal ambient light of room, so may not work in different light condition. But the problem can be solve by recalibrating the ADC value

Edge Dection Robot Using IR(analog)

The following video show the edge detection robot implemented using ATmega16 and two Analog IR sensors. The Robot uses two geared motor and one caster wheel at the front for the movement. The robot uses Ablab ATK-500 AVR trainer board. Motor driver is use to drive motor.

The code is shown below.

//PORTC is used for LED

//PORTD is used for motor driver

//PORTA for ADC channel input

#include<avr/io.h>
#include<util/delay.h>
#include"adc.h"
void main()
{
PORTD=0xff;
PORTC=0xff;

adc_init();
unsigned int x,y;
while(1)
{
x=read_adc_channel(0);
y=read_adc_channel(1);

if(x>150&&y<150)
{
PORTC=0xf0;
;
PORTD=0x09;//Left turn
}
else if(x<150&&y>150)
{
PORTC=0x0f;
PORTD=0x06;//Right TUrn
}
// for both sensor outside the table
else if(x>150&&y>150)
{
PORTD=0x09;
_delay_ms(3000);
PORTC=0b11000011;
}
else if(x<150&&y<150)
{
PORTD=0x05;//Forward Motion
PORTC=0b00111100;
}


}
