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 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.

Why do we need line following robot?

The line following robots is commonly used for carry children through shopping malls, homes, entertainment places, industries. The use of line following robotic vehicle is transport the materials from one place to another place in the industries. This robot movement completely depends on the track.

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

Procedure:

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 is a Roomba programmed?

A Roomba uses its piezoelectric sensor to detect the presence of excessive dirt and debris. When enough tiny dirt particles impact the sensor, electrical impulses trigger a built-in program, “Dirt Detect,” prompting the device to make a second pass over the same area for a more thorough cleaning.

How does Roomba find its way home?

Virtual walls send out infrared signals that Roomba picks up with the receiver on its bumper. When it picks up a signal from a virtual wall, it knows to turn around and head the other way. Roomba’s sensors allow it navigate your home with relative autonomy.
