A Flexible, Architected Soft Robotic Actuator for Motorized Extensional Motion

Abstract

A Flexible, Architected Soft Robotic Actuator for Motorized Extensional Motion In article number 2300866 by Ryan L. Truby and co-workers, a flexible, architected soft robotic actuator is reported that comprises a 3D printed, cylindrical handed shearing auxetic structure and a deformable, internal rubber bellows shaft. The actuator linearly extends upon applying torque from a servo motor, while maintaining high flexibility. The photomontage shows the soft actuator used as a crawling soft robot that can move through tight, tortuous surroundings. The mechanical deformability allows the actuator to passively adapt to its environment.
