Colourific — Robotic Toy Sorting System

Summary

Colourific is a robotic toy-sorting system built to organize objects by color in a safe and accessible way. Using LEGO EV3 Mindstorm hardware, it integrates color, touch, and IR sensors with DC and servo motors to classify and sort blocks in real time. A simple button-based interface allows users to choose target colors and block counts, making the system interactive and adaptable. The robot emphasizes safety and usability through a sturdy, child-friendly design with smooth edges and modular components. By combining embedded programming with inclusive design, Colourific demonstrates how robotics can deliver practical solutions that support both play and learning.
