Compliant pneumatic actuators have attracted the interests of the robotics community especially for applications where large strokes are needed in delicate environments. This paper introduces a new type of compliant actuator that generates a large twisting deformation upon pressurization. This deformation is similar to torsion in solid mechanics, and can be characterized by a twisting angle along the longitudinal axis of the actuator. To produce prototype actuators, a new fabrication process is developed that uses soft lithography. With this process, prototype actuators with a width of 7mm and a thickness of 0.65mm have been produced that exhibit a twisting rotation of 6.5 degrees per millimeter length at a pressure of 178kPa. Besides design, fabrication and characterization, this paper will go into detail on stroke optimization. © 2013 IEEE.
