Abstract

A variable-stiffness mechanism may include racks, pinion gears, spring elements, a cable, and a pulley. The variable-stiffness mechanism may be based on a variable-lever principal using the racks as a lever and the pinion gears as a variable pivot point. The pinion gears may be fixed in position relative to the pulley and coupled together by a gear-to-gear mesh. Alternatively, the pinion gears may be configured to translate relative to the pulley using a central drive rack and drive motor.
