4. Int r oduc t ion DBIT 4 Line-following robot is also called as line-sensing robot. Line follower robot is a machine that can follow a path. A Line Following Robot is an autonomous robot LFR is able to follow either a black or white line that is drawn on the surface consisting of a contrasting colour It is designed to move automatically and follow the plotted line.

5. Aim & Objectives Aim: The aim of a line follower robot using Arduino Uno and IR sensors is to autonomously navigate a path by detecting and following a contrasting line on a surface. Objectives: Design of the robot is to move automatically and follow the line. Robot is capable of taking various degrees of turns. Capable of adapting the robot for longer distance without any manual control. DBIT 5

7. Met h od o logy When both sensors sense light surface both wheels spins at same speed and robot goes straight. When “Left” sensor sense black line and “Right” sensor sense contrasting line, the robot moves left. When “Right” sensor sense black line and “Left” sense contrasting, the robot moves right. When “Both” sensors sense thick black line, the robot will stop. DBIT 7

9. Working with Circuit diagram 1.The line follower robot senses a black line by using a sensor and then sends the signal to Arduino. Then Arduino drives the motor according to sensors output. DBIT 9

10. o When both l e ft and r i g ht sens o r s e ns e s lig h t s urface then, the robot moves forward. o If both sensors moves on the black line, the robot stops. DBIT 10

11. o If the left sensor moves on a black line then the robot turns to the left side. o If the right sensor sense black line then robot turns to the right side until both sensors comes at the light surface. DBIT 11

13. Arduino UNO R3 Arduino UNO R3 is a low-cost and flexible. It is easy-to-use, programmable, open- source microcontroller board. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards. It can control relays, LEDs, servos, and motors as an output. Arduino UNO is a microcontroller board based on the ATmega328P. DBIT 13

14. Infr a r ed (IR) Sensor ⁎ When IR rays fall on a white surface, they are reflected towards the IR receiver, generating some voltage changes. ⁎ VCC - Supplies power to the module & needs to be connected to the VCC pin on the Arduino. ⁎ GND - It is the Ground Pin and needs to be connected to GND pin on the Arduino. ⁎ IR E m i t t e r - I n f r a r ed E m i t t e r LED ⁎ IR Receiver - The Infrared Receiver that receives signals transmitted by Infrared Emitter.

15. L298 Motor Driver L298 is one of the easiest and best ways to control DC motors. It is the two-channel motor driver that can control the speed and spinning direction of DC motors. Control Inputs: The L298 has following control inputs (IN1, IN2, IN3, IN4) that are used to control the direction (forward or reverse) and speed of the connected motors. Enable Pins: Each H-bridge (channel) has an enable pin (EN1, EN2) that, when set high, enables the corresponding outputs (OUT1 & OUT2) for channel 1 and (OUT3 & OUT4) for channel 2. DBIT 15

16. Rocker Switch Its function is to open or close an electrical circuit in a stable manner. Car Wheels It produces a rotatory function and moves the car from one point to another. Gear Motors A gear m otor is an all-in- one combination of a motor and gearbox. w i r es DBIT 16 Connecting wires are allow electricity to flow from one electrical component to another

17. DBIT 17 Adv a nta g e These types of robot movement are usually automatic. It is relatively cheap. This type of robot are simple to build. It is used for long distance. It is capable of taking various degrees of turns.
