When the hand is removed from the main arm unit, it doesn’t just sit there — it moves. It can “crawl” across a table, grip objects, and perform gestures on its own, like it’s got a brain of its own. But in truth, it’s the engineering and wireless connectivity behind it that’s doing the magic. A small joystick or app gives users the ability to steer or control the hand’s movement remotely.
Why is this useful? For people like Tilly Lockey or others with upper limb differences, this tech isn’t just cool — it’s empowering. Reaching for something that’s stuck behind a desk, or grabbing something fragile without having to twist your body awkwardly? The detachable hand can go there for you. It helps with real-life challenges and boosts independence. It’s a feature no one thought possible a few years ago, and now it’s changing lives daily.
What Makes the Hero Arm PRO Different from Other Prosthetics
There have been prosthetic arms before, even some with robotic fingers. But nothing comes close to the level of control, precision, and freedom that the Hero Arm PRO delivers. Most prosthetics require cables, straps, or bulky setups. Many are uncomfortable, stiff, and hard to personalize. What makes this the most advanced bionic arm is not just the cool tech—it’s how it actually fits into a person’s daily life.
This arm doesn’t just look futuristic—it feels futuristic. It uses wireless EMG sensors called MyoPods that pick up signals straight from the user’s muscles. That means when someone like Tilly thinks about moving a finger, the bionic arm just…does it. It rotates 360 degrees, is fully waterproof, and doesn’t need wires going into your skin. It’s also 3D-printed and customized to each person’s size and preferences, which means better comfort and less fatigue.
This level of seamless control and freedom is rare even in high-end prosthetics. That’s why the Hero PRO is setting a new standard, not just for prosthetic arms—but for what we think is even possible.
How 3D Printing Is Revolutionizing Prosthetics Like the Hero PRO
One of the biggest reasons the most advanced bionic arm exists today is because of 3D printing.
