Line Follower Robot Circuit:
Now a days robotics is the plays major role in the entire world and technology that deals with the design, construction, operation, and
application of robots and as well as computer systems for their control,
sensory feedback, and information processing.
- A Line Follower Robot system contains sensors, control systems, manipulators, power supplies
and software all working together to perform an assigned task.
- The most Important basic autonomous robot you can build is a line following robot,The purpose of this AVR tutorial-part 23 is to help you build a Line Following Robot using an inexpensive AVR chip.
Mechanical Design of Line Follower Robot:
Parts :
- Robot Chassis
- Robot Motors
- Caster Bullets
- Robot Wheels
- IR Sensor Cards
- IC L293D
- IC Atmega8
- Motor Clamps
- Switches
- Battery Holders
- Batteries
- Electronic Components
- Screws & Nuts
IR Sensor Placement:
- First of all attach motors, clamps and wheels as illustrated here. Next,
attach two caster bullets at the bottom of the
chassis.
- Finally, drill suitable holes in the chassis to fit all
remaining parts such as finished circuit board, sensor cards, battery
holder, pcb spacers, supporting clamps.
- Best location for main circuit board is the centre-top of the chassis,the infrared sensor cards (left and right) should be fitted at the
front-side of the chassis, in downward direction, so that infrared
sensor components.
- Line Follower Robot follows a path with black track on white surface. To sense the
track properly, infrared sensors must be placed on the chassis in such a
way that they are very close to the track level. Ensure that distance
between two infrared sensor card.
IR Sensor Card Circuit diagram:
The infrared sensor cards (left and right) on the bottom of the chassis for
detecting the black tracking indicant on the path. Each sensor card is a
combination of an infrared LED, infrared photodiode, and a comparator
chip works on 5V DC supply.
the default jumper condition (JP:1+2), output of the infrared sensor
card is at a logic-low (L) state, when it detects a black color, we need two identical infrared sensor cards; one
for left side, and other one for right side
