This project includes a model of a mechanically passive (i.e. spring-powered), cable-driven shoulder exoskeleton that was added to an existing dynamic model of the upper extremity. The dynamic upper extremity model, the "MoBL-ARMS Dynamic Upper Limb Model", is available on the following SimTK project page: Upper Extremity Dynamic Model (https://simtk.org/frs/?group_id=657). The exoskeleton model is described in more detail in the peer-reviewed article listed below. Please cite this article if the model facilitates or inspires your own research.
