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.
