A Survey in the Different Designs and Control Systems of Powered Exoskeleton for Lower Extremities

In this paper, previous studies in powered exoskeleton and their contributions in the field of robotics technology are presented, together with their corresponding control system. Specific problems and issues that were encountered and the solutio ns made to resolve the problems will be discussed. Gait cycle analysis and human body dynamic model will also be covered in the study to understand the biomechanics and the dynamics behind human walking.
