Driver On Line Follower Robot

Motor Drive On Line Follower Robot - To move the Line Follower 2 options can be used, namely motor or DC motor servo motor. If you want to use a DC motor, it must use a DC motor is mounted gear system (geared motors DC).Kind of like it is still difficult to find in the market, so the choice often falls to the servo motor.Another advantage of the servo motor is a servo motor can be controlled directly from the microcontroller PIC16F84 with no extra-Driver IC again.

Wheel Drive On Line Follower Robot - Wheels are used in line follower may vary - kinds, ranging from the brand, type, dimensions, and so forth. Line Follower Robot are generally categorized based on the number of wheels it has.Starting from the robot with two wheels, three wheels or four wheels. But that is commonly used is a robot with three or four wheels.

Placed behind a pair of wheels connected by two motors each - each have an independent pace.It is important that the robot can turn left and to right and set the desired rotation rounds. While the front wheels could use a caster wheel that serves as a buffer. Many brands of caster wheels that can be used, one of the most famous is from the manufacturer Tamiya. However, no cane akarpun so - if we want a cheaper and sometimes free, odor-preventing former rodadeodorant can used as a caster wheel.

In the Line Follower Robot Microcontroller Many types of microcontrollers that can be used in line follower robot, some examples include AT89C2051 (8051 Core), AT89C51 (8051 Core), ATmega8 (AVR Core), ATmega16 (AVR Core) and many more.

In the microcontroller, the program will be included so that the robot can adjust the rotation speed of each motor and able to perform the desired movement. Because the line follower robot speed is high enough, then some of the control algorithm needs to be applied to a robot capable of running smoothly. Control that can be a continuous control, PID, fuzzy logic, or the other.

Speed setting is important, especially when faced with change of trajectory, from a straight trajectory to bend or otherwise of the bend to the straight path. Just as when the robot moves fast and then find a corner, then the robot would be bounced. That requires a series of dynamic motor speed control depending on the type of trajectory is traversed. If the robot goes straight, the speed of the robot cultivated at a maximum. If the condition of the bend, then the speed is reduced depends on the sharpness of the bend. In essence, the speed of the robot is made flexible according to the situation on the ground. On the robot, the speed reduction can be done using the PWM (Pulse widht Modulation) controller, namely the reduction of speed by reducing the current to the motor.

Line Follower Robot with AVR ATMega8535

Line Follower Robot with AVR ATMega8535 - Make the robot line follower is exciting, especially for those who like to friends experimented with AVR microcontroller ATMega. "Line Follower Robot" is a robot designed to follow the trail (can be a line putus2 line or even a point to point). Creating a Line Follower Robot uses an AVR microcontroller ATMega 8535 is very possible and very reliable. Due to the design of a Line Follower Robot should we think that the trail will be followed step by step Line Follower Robot will be made to track or path in Line Follower Robot is passed. And of the Line Follower Robot needs tersbut feature2 owned by AVR microcontroller ATMega 8535 is sufficient and meets the needs of the Line Follower Robot. Line Follower Robot in the article with AVR ATMega8535 I made a simple graffiti to be possessed by a Line Follower Robot.

Function Block Diagram of Line Follower Robot with AVR ATMega 8535 :
  1. Line Follower Robot Sensor on can use a photo diode or photo transistor, this section serves to detect the presence of trajectory track.
  2. Keypad, this part of the function buttons to start / stop Line Follower Robot and as voters Line Follower Robot configuration settings for the field will be going through.
  3. Display, a part which serves to show the option of setting and the setting (it is enough that needs to be in view) of this section or the viewer can use a 7 segment LCD.
  4. Motor Driver, this part of a series of H Bridge DC motor driver. This section controls the motor in langsun. This section is an AVR microcontroller interface anatara ATMega with DC motor. I like to use the IC motor driver L298 family.
  5. ATMega8535 AVR microcontrollers, this section is the part that determines where the robot will be taken based on the data from the sensor. This section is set langkah2 Line Follower Robot in the conquest of the track.
