The Big Question
Aarav wasn't trying to win a trophy. He was thinking about people. specifically, people who need prosthetic arms but can't afford the expensive electronic ones.
He asked himself: "Can I build a working arm using only simple mechanics? No batteries. No sensors. Just clever engineering."
The "Aha!" Moment
Simplicity First
Instead of asking "what can I add?", he asked "what can I take away?"
Easy to Fix
If it breaks, you don't need a computer scientist to fix it. Just a screwdriver.
How It Actually Works โ๏ธ
Hinged Joints
Mimics real elbows and fingers.
Invisible Strings
Tension wires inside the arm pull the fingers closed when the elbow bends.
The Grip
Allows the user to hold cups, pens, and small objects.
Learning by Doing
Aarav didn't have a high-tech lab. He had constraints. And constraints make you creative.
