Abstract: The number of people with mobility disorder cause by stroke spinal cord injury or related disease is increasing rapidly.To improve quality of life of this people device that can assist them to regain the ability to work are of great demand. Robotic devices are generally used for purpose.The aim of this paper is to present the design and analysis of lower limb exoskeletons.The Exoskeleton is designed by Mechanical Design Procedure for linkages and against the Position values obtained from Gait Analysis.The Gearbox is designed using standard design procedure. This exoskeleton work on the principle of robotics by using sensors, actuator like DC motor. Gait analysis is used as a primary analysis followed by static and dynamic analysis of designed model.Static and Dynamic Analysis is performed in ANSYS Workbench. This exoskeleton will be used for paralyzed patient (paraplegia)as well as for the people who have had accidents for lower body.The limitation of this work is the same exoskeleton cannot be used for all person and a small defect in sensor and other electronic devices will stop the exoskeleton. Using this exoskeleton a paralyzed patient will be able to rehabilitate they will be able to perform stand to sit motion
Keywords: Dynamic Analysis, Gait Analysis, Lower Limb Exoskeleton.
