For the past three years, the e-NABLE community has been working very hard to create free and low cost 3D printed upper limb devices and tools that are aimed at helping children and adults who were born missing portions of their hands and arms – to aid them in everyday tasks like riding their bicycles with better balance, giving them the option to eat a sandwich with one hand and drink from a cup with the other, or perhaps more critically, the ability to write with a pen or pencil.
Students on this project team will add critical functionality to an existing base 3D printed hand/arm prosthetic and integrate the new device into the open source e-NABLE paradigm of easy customization and 3D printing.
The current iteration of the Raptor Reloaded hand is a normally-open and wrist driven device. The hand is actuated by a series of threads secured through each of the fingers. The hand then reopens via tied elastics. The hands are currently scaled to order based on measurement provided by the recipient. Improvements in the design would allow for a hand that is normally closed and that would allow for a better pincer grasp. The design is intentionally low tech to accommodate an international need.
