How do you make a path follow a robot?

How do you get a robot to follow a path?

All robots follow a path.

Here’s a pretty simple algorithm that could do the trick:

  1. If next point exists, go to step 2, otherwise, stop.
  2. Calculate distance and direction to next point.
  3. Turn robot to face next point.
  4. Travel the calculated distance.
  5. Go to step 1.

How do you make a line following a robot?

Step 2: Hardware Installation

  1. Assemble the 2WD Smart Car Chasis 2 Wheels.
  2. Connect the IR sensor to Analog to Digital and Comparator Module. …
  3. Then, connect the output pin to Arduino UNO analog pin. …
  4. Connect Vin to 5V and GND to GND in Arduino UNO.
  5. Then, connect the motor driver pin to Arduino UNO pin.

What is a path follower robot?

Abstract: The line follower robot is a mobile machine that can detect and follow the line drawn on the floor. Generally, the path is predefined and can be either visible like a black line on a white surface with a high contrasted color or it can be invisible like a magnetic filed.

What is path planning in robotics?

Motion planning, also path planning (also known as the navigation problem or the piano mover’s problem) is a computational problem to find a sequence of valid configurations that moves the object from the source to destination. … For example, consider navigating a mobile robot inside a building to a distant waypoint.

What is path following algorithm?

The goal of path following is reducing the distance and orientation error between a robot and a geometric reference path. Difference between path following and trajectory tracking is made clear by Aguiar et al. in [1]. Many path following algorithms for wheeled mobile robots have already been developed.

How does line following robot works?

A line follower consists of an infrared light sensor and an infrared LED. It works by illuminating a surface with infrared light; the sensor then picks up the reflected infrared radiation and, based on its intensity, determines the reflectivity of the surface in question.

How do you make a simple line follower robot with Arduino?


  1. Step 1: Connect the circuit as shown in the schematic.
  2. Step 2: Use the Arduino IDE to write your own code.
  3. Step 3: Upload your code to the Arduino and connect it to the batteries or you can even use a power bank to run the Arduino.
  4. Step 4: Test it on a black path.

How do I make a line following robot without Arduino?

Line Follower Robot Without Arduino or Microcontroller

Which sensor is best for building line follower robot?


For line sensing operation, IR sensors are the one which are widely used for the development of a line follower robot. There are some basic things to follow where white surface of the black line reflects light and the black line receives it after the transmission.

How does the robot will use the IR sensor?

An IR receiver captures the reflected light and the voltage are measured based on the amount of light received. Infrared sensors are used in a wide range of applications including here proximity robotic applications for distance and object detection, or color detection and tracking.

What is navigation and path planning?

Global navigation strategy deals with a completely known environment. Local navigation strategy deals with the unknown and partially known environment. The path planning algorithm for a known environment is based on a classical approach such as CD, RA, and APF.
