Hey everyone! We are Prachi Solanki and Vanshika Sharma, and we’re students in the AI&DS branch at the Prashanti Group of Institutions.
If you’ve ever walked into a lab and felt that rush of excitement when a piece of code finally turns into a physical movement, you’ll know exactly how we feel right now. For our latest project, we decided to tackle a real-world problem: how to make industrial sorting faster, cheaper, and smarter. The result? Our very own Colour Sorting Project.
Why Colour Sorting?
We didn’t just want to build something that looked cool; we wanted to build something that worked for the world. Whether it’s a farmer trying to sort high-quality seeds from bad ones or a recycling plant trying to separate plastic from paper, the manual process is slow and tiring. We thought, “Why not let AI and robotics do the heavy lifting?”
Getting Under the Hood (The Tech Stuff)
The concept sounds simple—see a color, move a lever—but getting the precision right was the real challenge. We used a color sensor as the “eyes,” a microcontroller as the “brain,” and a servo motor as the “arm”.
Here’s the logic we programmed into it:
The Neutral Zone: When the machine is waiting, the servo stays at 90°.
The “Red” Move: As soon as the sensor detects a red object, it sends a signal to the motor to pivot to 50° and drop it to the left.
The “Yellow” Move: If it sees yellow, the motor swings the other way to 140° to sort it to the right.
More Than Just a Lab Experiment
What we’re most proud of is how this can be used outside of Prashanti. During our research, we realized this technology has huge potential in:
The Food Industry: Perfect for sorting seeds or grains quickly.
Agriculture: Helping grade vegetables by color and quality.
Recycling: Making waste management much more efficient by separating materials automatically.
Final Thoughts
Building this project taught us that engineering isn’t just about formulas in a textbook; it’s about solving problems with your own hands. A huge thanks to our mentors at the Prashanti Centre of Excellence for giving us the space and the tools to innovate.
We’re just getting started with AI and Robotics—stay tuned to see what we build next! 🚀
