Thesis & Summary Draft #1

Thesis: The Hero Arm is amongst the best bionic prosthetics available to the public, being adeptly functional and affordable.

The webpage "Hero Arm" from Open Bionics (n.d) introduces the Hero Arm bionic prosthetic and shows how it is a great advancement in prosthetic technology, and how it enables those who have lost their limbs. The Hero Arm is a forearm prosthetic that functions by picking up electric signals from the user’s arm muscles using electromyographical (EMG) electrode sensors. These signals are translated into instructions, which tell the arm how to move. According to Open Bionics (n.d), the Hero Arm is capable of performing six different grips, allowing the user to execute basic actions such as eating with utensils and brushing teeth. It also features a 180° rotatable wrist for added flexibility. The Hero Arm also has a 'Freeze Mode', which locks the position of the hand temporarily, allowing the user to relax. In terms of build quality, the Hero Arm is 3D printed from a soft flexible elastomer with integrated breathable vents, allowing it to comfortably fit the user's arm and keep it cool. The arm also features Open Bionics’ proprietary BOA Fit Adjustment technology, which enables the frame to be tightened or loosened via an adjustment dial. Together with its fluted shape, it ensures a perfect fit for the user. Finally, the Hero Arm also has interchangeable covers, allowing users to change its design with ease.
