Exoskeletons have the potential to change pretty much everything about health, granting more motion and mobility to everyone from seniors to children. But no story is more touching, or shows the potential of these tools, than the story of a two-year-old named Emma.

Emma was born with a neurological disorder that left her unable to lift her arms. She's otherwise completely healthy, but she has no mobility in her arms under her own power.

This is where the exoskeleton comes in. The Wilmington Robotic Exoskeleton, or WREX, was scaled down for Emma. As she grows, new ones will be printed out using 3D printing technology. It means Emma can use the WREX as she grows.

In short, technology ensures this little girl will be able to have a normal life. Chalk up a heartwarming for robotics.
