ORTE Exoskeleton: Kinematic Analysis and Dynamic Modeling

ORTE is a robotic platform developed to restore the mobility to the shoulder complex and elbow joint of upper limb impaired patients. ORTE pretends to be an effective and objective tool for the rehabilitation staff. This work presents the kinematic analysis and dynamic modeling of ORTE, a 6 Degrees-of-Freedom upper limb rehabilitation exoskeleton. The dynamic model of the mechanism is used to find the required torques to perform a set of different trajectories of daily living activities as eating or taking an object. This allows the optimal selection of actuators for this rehabilitation system.
