Project Overview

The Problem

Parkinson’s disease causes involuntary tremors, making daily activities like eating difficult and messy, leading to frustration and loss of independence.

Our Solution

We developed a low-cost self-stabilizing spoon that compensates for hand tremors in real-time. By utilizing an MPU6050 sensor and precise servo control, the spoon maintains a steady level position.

  • Core Concept: PID-based active stabilization.
  • Hardware: Arduino Nano, MPU6050, MG90 Servos.
  • Goal: Affordable assistive technology.
