Phototropic Light-Seeking Robot

Description

The Phototropic Light-Seeking Robot is an intelligent student project that demonstrates how robots can be programmed and designed to move toward a light source, inspired by phototropism in plants. This model integrates simple electronics and robotics to showcase how sensors control robotic movement.

The robot is built on a chassis with BO wheels and a caster wheel for stable mobility. It uses BO motors, secured with nuts and bolts, to drive the movement of the robot. The LDR (Light Dependent Resistor) module serves as the sensing unit, detecting variations in light intensity. When light falls on the LDR, it changes resistance, which is processed by the L293D motor driver module. This module directs the BO motors to move toward the detected light source.

Supporting components like the 7805 voltage regulator, connecting wires, and 9V battery clip ensure safe power distribution and reliable operation. The PCB setup helps integrate all the electronic elements seamlessly.

This project is highly educational for students as it teaches the concepts of sensors, motor control, automation, and bio-inspired robotics. Real-world applications of light-seeking robots include solar tracking systems, automated lighting control, and search-and-rescue operations. It is an ideal project for science exhibitions, STEM learning, and robotics competitions.
