Design of a Robotic Device for Arm Rehabilitation

Abstract

This article presents the conceptual design of a robotic rehabilitation device focused on the recovery of the elbow joint, aimed primarily at individuals who have suffered a cerebrovascular disease or trauma to that joint. The device was developed following Ullman’s mechanical design methodology, which allowed the project to be structured systematically. The robot enables repetitive flexion-extension movements of the elbow, with the goal of restoring mobility to the affected upper limb.

To ensure the mechanical integrity and functional reliability of the proposed system, a structural validation was conducted through finite element analysis, along with studies for the selection and design of the electronic and instrumentation components. This development represents a step forward toward accessible, functional, and efficient rehabilitation solutions.
