Robotic Exoskeletons assist patients with impaired mobility due to aging and spinal cord injuries, which is becoming increasingly more prevalent. However, the present exoskeletons are either bulky or do not provide necessary power. The design needs to be improved with state of the art mechatronics. In this project, a comprehensive study of design of exoskeletons has been conducted. A new model is designed that is a combination of components that optimizes the size and weight, yet yields highly assistive torque. The future work will be to test it for functionality and robustness.
