FlexiGrip: Multi-Gesture Robotic Hand with Expressive Motion

FlexiGrip is an Arduino-based robotic hand designed to mimic human hand gestures using five servo motors. The system performs a variety of motions including opening, closing (fist), thumbs up, pointing, victory sign, claw grip, "OK" sign, waving, relaxed hand, and gun pose. Each gesture is executed with smooth, linear motion and includes visual and sound feedback via LED and buzzer.

This project serves as an ideal prototype for prosthetics, gesture-based robotics, or educational demonstrations in embedded systems and servo control. With modular code structure, it can easily be extended for Bluetooth, voice, or sensor-based gesture input.
