New Closed-Form Kinematic Model for Fiber-Reinforced Elastomeric Enclosures (FREEs)

Fiber-Reinforced Elastomeric Enclosures or FREEs are a class of cylindrical soft pneumatic actuators that can rotate as they contract or extend. Previous descriptions of these actuators were unwieldy and required complex iterative evaluations to predict the kinematic behavior. The model I developed dramatically simplifies the description of the actuators into a closed-form kinematic model with three design parameters and one state.
