Here is an exoskeleton for children that helps with spinal muscular atrophy. The CSIC child exoskeleton weighs only 12kg and has an aluminum and titanium construction. It helps patients walk to avoid issues associated with the loss of mobility.
The exoskeleton has a robotic frame that attaches to children’s legs and torso, helping them stand up and walk. The robot has 5 motors in each leg that act as artificial muscles and can adapt as children grow. Promising, don’t you think?
