Two co-located 12V DC motors act in opposition to change effective joint stiffness—just like a safe robotic joint. The MPU6050 IMU measures output compliance in real time, giving you a wearable platform to explore force‑modulated impedance control.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou’ll assemble a gait tracking system where FSR 402 force‑sensing resistors detect foot strikes, while dual motors co‑activate to vary joint impedance. An Arduino Mega 2560 orchestrates sensor fusion—magnetic encoders capture shaft position, INA219 modules read motor current, and the OLED displays live stiffness.
