Arm Orthosis

Arm Orthosis developed for Master Thesis, based on the design of the 3D printed WREX.
A passive mechanism is used to compensate for the gravity of the arm weight using regular desktop elastic bands or similar, a servomotor can be attached to improve the control of the mechanism. The design was developed to aid children with progressive muscular dystrophies.
