Wilmington Robotic EXoskeleton (WREX) Arm Remake

thingiverse

Still perfecting the last details of this project. The wrist support needs some adjustments as well as the binding posts. In conclusion, the WREX arm prints and functions properly. Binding posts can be replaced with shoulder bolts if desired. Also, The holes should be sized for #10 socket head cap screws. If scaling is required up or down, adjust your screws accordingly. I will update these files as possible. Assembly instructions will be included in the future as well. The Wilmington Robotic EXoskeleton (WREX) Arm is a robotic orthosis designed by Jaeco Orthotics. The original design allows for four degrees of biomechanical motion and uses elastic bands to resist gravity's pull on the user's arm. Two sets of bands independently support the forearm and upper arm. This device was created for individuals with neuromuscular disorders, enabling them to functionally perform daily tasks such as feeding and writing. More information about the WREX can be found here: http://jaecoorthopedic.com/products/products/WREX%3A-Wilmington-Robotic-EXoskeleton-Arm.html The original design was cumbersome and made of mostly metal parts. Scientists from the Nemours/Alfred I. duPont Hospital for Children created a 3D printed version for children that is lightweight, easily adjustable, and much more cost-effective (The original WREX sells for approximately $2400). More information about the "Magic Arms" can be found here: http://www.core77.com/posts/23101/wrex-3d-printed-magic-arms-and-the-future-of-pediatric-prosthetics-23101 We managed to find STL files for the WREX Arm and printed an early model of the 3D printed WREX. The design was fragile and difficult to scale without source files. This is our version of the WREX. The connectors are customizable in length to fit all different sizes. This model is designed to be attached to a child's chest brace via the back mount. The left elbow hinges belong to the original design team. As of now, I do not have a version available for the right arm.
