The system combines an electromagnet, IR phototransistors for position sensing, and a hardware feedback network to maintain stable levitation. The control loop required careful tuning—higher gain improved responsiveness but introduced oscillation, while lower gain reduced stability. Once stable levitation was achieved, I added wireless power transfer to deliver energy to the levitated object. The final system demonstrates a small light source suspended and powered without visible wiring. A significant portion of the work involved iterative tuning of sensing and control parameters, particularly to manage noise and maintain stable operation over time. Small changes in the feedback network often had immediate and visible effects on system behavior. The project was nominated by Professor Oscar Vazquez for presentation at UCSD’s Undergraduate Research Conference.
