Fig. 3: An actual-size, single-side PCB for the line follower robot Fig. 4: Component layout for the PCB of Fig. 3 Motor driver L293D is interfaced with sensors and controls the 12V geared DC motors ...

When both sides are on the black surface, both motors are activated. Hence, the robot follows a straight line. A PCB layout of the relay-based line follower is shown in Fig. 6 and its components ...

The repository includes the Arduino code for the robot, which is written in C++ and uses the PID library for control. The code is well-documented and easy to modify for different use cases.

the aim of this project is to make an Arduino robot or DFrobot miniQ 4WD robot like PCB robot, but using cheap material and adding I2C to the car for extension ...

Building line following robots is fun and easy. Building a line-follower that is this tiny is a different story. The surprising thing for us is that despite how it looks, this robot whose name is ...

A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a ...

Hence, the processor is going to decide the proper commends and then it sends them to the driver and thus the path will be followed by the line follower robot. In this Paper, we have illustrated the ...
