Advanced Line & Wall Following Robot

This robot is designed to precisely follow lines and walls. The core of the robot is an Arduino Mega. It is constructed on a veroboard, with all components hand-soldered, as PCB services are not widely available in our country. The robot is equipped with eight sensors for line detection and three ultrasonic sensors for wall detection. The wheels are 3D printed because this specific size is not available in the market in Bangladesh. I have won 8 national awards from various universities in Bangladesh with this robot.
