The Hero Arm

The Hero Arm is a lightweight myoelectric prosthesis

with a versatile multi-grip bionic hand, an adjustable and

breathable socket, high-performance motors and

batteries, and empowering aesthetics. It is the most

affordable multi-grip bionic arm in the world, less than

half the price of its nearest competitor. The Hero Arm is

durable, reliable, medically approved, and FDA registered.

It is available through prosthetics clinics for both adults

and children as young as eight years old with acquired or

congenital below-elbow upper limb differences.

Open Bionics

Open Bionics was founded in 2014 by Joel Gibbard and

Samantha Payne with the goal of developing affordable,

assistive devices that enhance the human body. In other

words, we turn disabilities into superpowers. Based in

Bristol in the U.K., we’re building Hero Arms for people

with limb differences all over the world. Your clinician will

send us a 3D scan or cast of your residual limb, and we

custom build your Hero Arm.

“When I first received my

Hero Arm I was absolutely

blown away. To be able to

put it on and just start

moving the fingers straight

away was just amazing.”

- Kim Smith, from Milton

Keynes, U.K.

Engineered especially for you

We receive a 3D scan or physical cast of your residual

limb from your prosthetist to create a custom-built

prosthesis. Your Hero Arm socket is comfortable,

breathable, and adjustable, which means it’s easy to

take on and off while providing you with the best

possible fit.

Intuitive and effortless

With the Hero Arm, technology is at your fingertips.

Literally. Special EMG sensors within the Hero Arm

detect muscle movements, meaning you can

intuitively control your bionic hand. You’ll be able to

cycle through a variety of grips (hook, tripod and

pinch) and receive feedback through haptic vibrations,

beepers and buttons.

“I can grip a toothbrush, use a

knife and fork, brush my hair

and play video games without

having to tape the controller

to my hand like I used to.”

Durham, U.K.

“Zak’s previous prosthetics were a little

bit heavier and not as user-friendly to

him, and so he wasn’t overly excited to

use them at the time. The Hero Arm is

lighter, and he had more input into the

colour and the design, so he felt more

part of the process.”

- Lesley Dubin, (Zak’s mum) from

Michigan, U.S.A.

Lightweight, powerful, strong

Even though the Hero Arm is powered by high performance

motors, advanced software and long-lasting batteries, it’s

lightweight and super sleek. The hand comes in three sizes,

and at 280g – 346g (0.62lbs – 0.76lbs), is the lightest on the

market. The full prosthesis weighs less than 1kg (2lbs). It’s

strong too, able to lift up to 8kg (17.5lbs).
