Develog #1
Today was Day 1 for my desk buddy.
I designed half of its case using Tinkercad, as I am a beginner, and soldered some wires to the 1.3-inch OLED screen. I am planning to complete the remaining part of the case tomorrow and start wiring after that.
Devlog 2
Completed making the Desk Buddy Case . Now the thing left is to solder all the components and prepare the code and test it and if it runs perfectly then fit all the items into this case and close it.
I am using TinkerCad because I am very new to 3D designing.

5IR Line Follower Devlog — Day 3
Today we made good progress on the mechanical assembly of our 16IR Line Follower Robot .
We permanently mounted the BTS7960 motor drivers onto the chassis and completed the motor connections. We also installed the caster wheel, but ran into an unexpected problem. The caster wheel we had was around 2.25 cm tall, which made the front of the robot sit higher than required. We searched for a smaller caster wheel on Amazon and other platforms but couldn’t find one that matched our requirements.
Instead of waiting for a replacement, we decided to modify the existing caster wheel ourselves. We carefully trimmed the extra material and reduced its height from 2.25 cm to 1.79 cm, which brought the chassis to the desired level and improved the overall balance of the robot.
With the motor drivers mounted, motors connected, and the caster wheel modified and installed, the robot’s hardware assembly is now much closer to completion. The next step is to complete the wiring between the ESP32, the 16IR sensor array, and the motor drivers before moving on to software testing and calibration.

Today was the first day of building our 16IR Line Follower robot.
Chinglen and I started working on the initial development and planning of the robot. We worked on writing the first motor control code and preparing the hardware setup.
We soldered the connections for the N20 600RPM geared motors and mounted the 16IR sensor array onto the chassis. We also started planning the complete electronics layout — deciding the positions of the battery, BTS7960 motor driver, and ESP32 38-pin board to keep the design compact, balanced, and easier to wire.
The next steps will be completing the wiring, testing sensors and motors, tuning the control system, and improving the robot’s speed and stability.
This project may take around 1 month to complete because we want to properly test and optimize every part of the robot.
Hardware used:
16IR sensor array
ESP32 38-pin board
2 x BTS7960 motor driver
2 xN20 600RPM geared motors
3d PrintedCustom chassis
What do you think will be the biggest challenge: PID tuning or sensor calibration?

16IR Line Follower Devlog — Day 2
Today we continued working on the electronics setup of the 16IR Line Follower project.
We powered the BTS7960 motor driver and added the buck converter to manage the power supply properly. After that, we soldered the required wires to the ESP32 38-pin board and started preparing the connections for the complete system.
The next steps are to connect the ESP32, BTS7960, and IR sensor array together, attach the motors, and permanently mount the electronics onto the chassis. We are also focusing on keeping the wiring clean and making the overall setup more reliable for testing.
The main electronics layout is now coming together, and the robot is moving closer to the final assembly stage.

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.
