This project is the primary phase to develop a prototype of a lower limb exoskeleton through the implementation of novel hardware and software techniques that will overcome specific issues those current exoskeletons suffer from, such as lack of robust controllability, bulkiness, and actuation performance. At this phase, a knee exoskeleton with a linear actuator has been constructed. It is controlled by using data received from electromyography (EMG) signals. Furthermore, 3D printed parts of the exoskeleton frame have been developed in order to reduce weight and for rapid prototyping. The device is to be designed as an assistive device for a non-handicapped person. The main requirement of the device is to aim more less 20% of the knee joint torque of the average human male (20-35 years) during walking. Furthermore, preliminary studies on electromechanical properties of soft robotic materials have been performed in order to explore their capabilities for this application
