5IR LFR - Stardance

Ship #1 Pending review

@AnshAgarwal on 5IR LFR · about 1 month ago

I made a 5IR Line Follower Robot using an ESP32 as the main controller. The robot uses 5 digital IR sensors for line detection and an L298N motor driver to control 300RPM geared motors. I designed the sensor mapping, created the code, assembled the hardware, and completed the full working robot. The main challenge was tuning the sensor logic and movement control so the robot could smoothly handle different paths like loops, 90-degree turns, and curves. I am proud that I was able to build, code, and test a fully functional line follower robot in around 1 hour. To test the project, place the robot on a black line track, make sure the batteries are charged and the sensors are aligned properly, then the robot will automatically detect and follow the path.

Today I started and completed my 5IR Line Follower Robot. I worked on the complete build process, including planning the sensor placement, making the circuit connections, and developing the code for the robot.

The robot uses 5 digital IR sensors connected with an ESP32 to detect the line. I created the sensor mapping and programmed the movement logic to control the motors through an L298N motor driver.

After testing and tuning the code, the robot was able to follow the track properly and handle different paths like curves, loops, and 90-degree turns. I also completed the power setup using two 2200mAh 3.7V Li-ion batteries with a buck converter for stable power.

The complete robot was built, coded, and tested successfully in around 1 hour.

Hardware used:

ESP32
5 Digital IR Sensors
L298N Motor Driver
300RPM Geared Motors
2x 2200mAh 3.7V Li-ion Batteries
Buck Converter
Robot Chassis

This was a quick prototype build to test my line following system and understand the performance of the sensor mapping and control logic.
