The Wilmington Robotic Exoskeleton (WREX) is an assistive device made of hinged metal bars and resistance bands. It enables kids with underdeveloped arms to play, feed themselves and hug. For our biomechanics class, we attempted to replicate one from open source designs on the internet. We hoped to get some inspiration for what would become the limb control project.
We started with a basic cardboard proof of concept. Some basic calculations gave us ballpark dimensions for the parts. Surprisingly, even though it was cardboard, it did indeed make limb movement easier.
The next step, full fabrication required more sturdy parts and metalwork.
