It is the exoskeleton which ignited my love for robotics, a device which both mirrors and enhances human function without replacing it. As with most technology, as the robotic exoskeleton develops it is moving away from bulky and functional to sleek and precise.
One such example of this development is the Cyclone Rope Piston by Rise Robotics. Rise Robotics has created an actuator (motor) which, paired with cables efficiently transfers power to the user. Just as a particular movement, such as holding something while bending and straightening the arm, is easier if a muscle is able to work throughout the entire range of motion, this motor helps generate power throughout the entire movement of the user. The development of such a motor potentially makes an exoskeleton much more functionally strong by generating more efficient power throughout the entire range of movement of the user.
The Cyclone Rope Piston allows for a lightweight wearable robot to assist with either strenuous activity for an able-bodied person, or movement assistance for rehabilitative purposes. This product is still in the funding phase.
For a more detailed explanation of the impressive and innovative mechanics of this system, I would recommend watching the extremely well made video below:

Me and the guys at work were drooling over this rope piston today, I’ve never seen anything like it. Thanks for sharing!
