THE FLIGHT SOURCE SPRING
It worked by using tensile rope elements in tandem with the tessellated diamond shaped pieces of fiberglass. Nicknamed the "Flight Source", the spring proved to be incredibly power dense compared to traditional helical steel springs.
Spring innovations lead Rise™ Robotics to compacting the fiberglass elements into a dense and modular assembly. As a successful component, Rise™ Robotics found it as an answer to the robotics industry where power density is a much desired trait.
