Abstract

A study demonstrates two configurations of rotary actuators that enable the conversion of peristaltic motion to torque. In the first configuration, the inflatable stator surrounds a hard plastic rotor. In the second configuration, the stator sits inside a rotor made of another elastomer. These two configurations lend themselves to unique sets of applications, such as winches and squishy wheels. The repeated sequence of inflation and deflation generates the staggered turning of the rotor. With increases in the frequency of sequential actuations, the continuous nature of the rotary motion increases.
