From the time the human race has evolved many have faced the difficulty in walking, standing, balancing and so on. About 13.7 percent of the world's population have a motor disability with serious difficulty in walking or painting balance making them among the largest minority groups on earth. Through this paper, we will be going to discuss the earlier research and the functions of the exoskeleton. The paper provides an overview of the hardware, sensors, actuators, and control system for the performance of the exoskeleton. 3D prototype of the model is designed and the simulation are performed to achieve a low cost exoskeleton for the medical and defence purposes.
