Often asked: How To Build A Line Following Robot?

How do I make an Arduino line following robot?

Working of line follower is very interesting. Line follower robot senses black line by using sensor and then sends the signal to arduino. Then arduino drives the motor according to sensors’ output. Here in this project we are using two IR sensor modules namely left sensor and right sensor.

How does a line following robot work?

The workings of a line follower robot are pretty straightforward. These robots have the capability to detect a black or dark line on a lighter surface depending on the contrast. These robots usually use an array of IR (infrared) sensors in order to calculate the reflectance of the surface beneath them.

How do you make a robot follower?

How do you make a line following robot on Raspberry Pi?

Make sure the Raspberry Pi is turned OFF. Connect the VCC pin of the IR line sensor to pin 1 of the Raspberry Pi. Connect the GND pin of the line sensor to the blue (negative) ground rail of the solderless breadboard. Connect the OUT pin of the line sensor to pin 21 (GPIO 9) of the solderless breadboard.

Which sensor is used in line following robot?

The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED.

How do I stop a line follower robot?

If the right sensor sense black line then robot turn right side until both sensors comes at the white surface. When the white surface comes robot starts moving on forward again. If both sensors come on the black line, the robot stops.

How do you make a line following a robot without a microcontroller?

Line Follower Without Microcontroller

  1. Step 1: COMPONENTS. 1) IC7805 Voltage Regulator – 1.
  2. Step 2: WORKING OF a MOTOR. We will be using two 500rpm DC motors here, you can use motors with different rpm as per your requirement.
  3. Step 3: ASSEMBLING. Give the connections as per the circuit given and place the whole setup on the chasis.
  4. Step 4: LINE FOLLOWER.

Why IR sensors are used?

Infrared sensors are used to sense characteristics in its surroundings by emitting and/or detecting infrared radiation and are capable of measuring the heat being emitted by an object and detecting motion.

What is a line tracker?

A Line Tracker mostly consists of an infrared light sensor and an infrared LED. This allows the sensor to detect a dark line on a pale surface, or a pale line on a dark surface. The Line Tracker allows your robot to follow a pre-marked path and allows humans to indirectly control the robot while it is autonomous.

Which component will you use to move the robot?

Actuator. The actuator is a component that functions as the joint of the robot, which allows a robot to move the arm up and down or rotate, and it converts energy into mechanical motions. It may be difficult to grasp this concept, but think about motors as an example.

How can we make robot in microcontroller?

The two IR sensors are connected to P2. 6 and P2. 7 pins of the microcontroller. Arrange the chassis and connect the four wheels of the robotic vehicle to the motors which are in turn connected to the microcontroller.

How do you make a Raspberry Pi robot?

What do you need to build a Raspberry Pi Robot?

  1. Raspberry Pi board.
  2. Motor driver, E.g. L298 – The intermediate device between your microcontroller, batteries, and motors.
  3. DC Motors – Provide the drive for wheels to rotate and allow for movement.
  4. Ultrasonic Distance Sensor – For robot detection of nearing objects.
