The light tracking robot is a mobile machine that is able to detect and track the light source in the trajectory of displacement. The concept of this robot following the light is very simple. Includes two LDR sensors, one in the front and one in the back. When the light falls on the front LDR sensor, the robot will move forward. Similarly, the robot will move backwards when light falls on the back LDR sensor.The robot line follower is a mobile machine that can detect and follow the line drawn on the ground. In general, the route is predefined and may be visible as a black line on a white surface with a high colour contrast or it may be invisible as a magnetic field. Therefore, this type of robot must detect the line with its infrared (IR) sensors that are installed under the robot. The robot line follower is a useful robot that is used in warehouses, industries and stores, etc., where it follows a dedicated path.
This robot is an automatic robot, that is, no manual control is needed. The robot will move forward or backward depending on the intensity of the direction the light is over. Here, we will use two analog light sensors to measure the intensity of light. The two sensors will be placed on the front and rear side of the robot. When there is a change in the intensity of light on either side of the robot, it changes the output of the value of the analog light sensor on that side and this change will be detected by the ATmega16 microcontroller. But the outputs of the two analog light sensors are of an analog nature, so these signals can not be processed directly by the microcontroller. To do this, we will use the ADC of the ATmega16 microcontroller to convert the analog signals into digital values. After converting the analog signals from analog light sensors to digital values, the ATmega16 microcontroller will compare the values of the sensors with each other. If the value of the front sensor is less than the value of the feedback sensor, the ATmega16 microcontroller will send the forward control signal to the robot motor controller (L293D) of the robot to move the robot forward and if the value of the sensor The ATmega16 microcontroller will send the control signal backwards to the robot's DC motor controller (L293D) to move the robot backwards.
