From Code to Motion

I wanted to understand how a robotic hand could move—not just mechanically, but responsively. I began by programming a hand to perform specific finger movements, then pushed the idea further by building a sensing glove that allows another robotic hand to mirror my own movements in real time.

Programmed Robotic Hand

I started with a simple question: could I make a 3D-printed hand move on its own? I added motors, connected the electronics, and taught myself how to program each finger. After many tests and adjustments, the hand could finally open, close, and perform movements through code.

This was the first time one of my hands moved without me physically touching it—and it made me wonder how much more naturally I could control it.

Motion-Mirroring Hand

Once I could make the robotic hand move through code, I started wondering: could it move with me instead? I built a sensing glove that tracks my finger movements, so when I move my hand, the robotic hand mirrors those motions in real time.

For me, this was a big step—from telling a machine what to do to creating something that could respond directly to a person.

What Comes Next

From programmed movement to real-time response, each version has opened a new question. I want to keep building, testing, and learning where those questions can lead next.
