Hardware Board Design and Simulation of Lower Limb Rehabilitation Robot

Today, the intelligent systems and robotics have turned to one of the most flourishing areas of research and technology development. Rehabilitation is one of non-pharmacological treatment within the public health system, which generally means restoring the capabilities to the maximum independence. The process of empowering muscles in order to make them to a normal and common value is an expensive and prolonged work.; There are some commercial exercise machines used for rehabilitation purposes. However, these machines have limited use because of their insufficient freedom in motion. Hence, it is clearly necessary to use Mechatronic technologies in rehabilitation area.This study aims to describe the functionality of its hardware and software board controller in performing patients’ rehabilitation. Simulation has been done using Simulink MATLAB. Furthermore pulse-width modulation method is used to program ATmega16 microcontroller to control mechanical part of robots.
