Mechanical Design Procedure and Modelling for 8-DOF Upper Limb Rehabilitation Robotic

Treating muscular medical injuries that impede movement of the human body has become of wide interest because of the importance it holds for improving the lives of people who are exposed to this type of injury. During the past years, several studies have attempted to create a robot that works to rehabilitate the injured upper limbs of the human body. In this research, a curriculum for the procedures will be developed for designing a medical robot by displaying the volumetric tolerances for this robot according to the age and weight of the injured person and the weight and volumetric constants for each part of the robot to be used in the mathematical model that is used to move this robot. Then the design of a robot with 8 DOF will be presented and examined using finite element analysis (FEA) in order to assess its ability to withstand and function in accordance with the load exerted by human weight. The upper limb exoskeleton model is subjected to analysis utilizing the Ansys® software, which facilitates the execution of von Mises stress analysis.
