New structure of pneumatic networks actuators for soft robotics

Abstract

Pneumatic actuators (referred to as pneu‐nets) are drawing increasing attention due to their high customisability, ease of fabrication and innate softness. The actuator's ability to bend is one of the important parameters characterising its performance and related to its structure. Some structures are developed. In this work, a new structure (NS) pneu‐nets is developed, and its bending ability is compared with the currently common Mosadegh pneu‐nets structure (developed by Mosadegh). These two are analysed in two aspects: the trajectories of the pneu‐nets actuator's tip, and the defined angle of bending. The results indicate that the NS pneu‐nets actuators are able to achieve greater bending at higher pressures and can be lightweight. These pneumatic actuators provide improved structure for soft robotics.
