Continuous Passive Motion Machine for Elbow Rehabilitation Report

This report presents the design and development of a Continuous Passive Motion (CPM) machine for elbow rehabilitation. The project involved designing the mechanical and electrical components, including the selection of appropriate hardware such as DC motors, servo motors, and microcontrollers. The report details the objectives of the project, which included designing a CPM machine with automatic range of motion assessment, developing speed control using a PID control algorithm, and creating a graphical user interface (GUI) for the system. The report also outlines the student's responsibilities, including mechanical and electrical design, component selection, and the application of engineering knowledge and skills. The project aimed to provide two degrees of freedom for the elbow joint. The student used Arduino Uno R3 microcontroller and potentiometer to measure range of motion. The report also addresses identified issues, such as the machine's limited scope, and proposes solutions, like integrating it with other rehabilitation devices and an advanced speed controller. Finally, the report discusses the project's overview, the student's contributions, and the potential for innovative and creative work in future developments.
