RoboHand

Hi everyone!
This is my first project, and I’m really excited to share it with you.

The Robo Hand is where creativity, engineering, and a bit of stubborn determination all came together. It started with a simple thought: What if I could build a robotic hand that actually moves like a real one? Step by step—through 3D printing, wiring, coding, and a LOT of servo testing—that idea slowly became real.

Using two ESP32 boards, tiny servos, fishing line, magnets, and plenty of persistence, the hand started to come to life. Each button on the remote controls a finger, making it open, close, and move surprisingly smoothly. The whole thing runs on a custom battery setup, communicates through ESP‑NOW, and is held together with PETG parts I printed myself.

But this project wasn’t just about building a device. It was about learning—fixing buzzing servos, tweaking code, figuring out wiring, and refusing to quit until everything worked the way I imagined. And in the end, I ended up with a robotic hand that actually responds to me, one finger at a time.

For me, it’s proof that with curiosity, patience, and a little bravery, you can build something awesome completely from scratch.
