Over recent years, studies on soft mechanism are rapidly being paid to attention especially in pneumatic actuator field. Good actuator should be able to provide sufficient force and flexibility in movement, hence bending motion is vital criteria needed in soft robotic actuation. In this paper, a solution to soft bending pneumatic actuator is proposed in which several patterns fiber weave designs are introduced. The objectives of the simulations is to investigate which weave patterns combination of fiber reinforced actuator models yields the best bending characteristics and its relation to the contraction or extension characteristics shown by single weave pattern actuator models. From the results, when two patterns of fiber weave are attached together to form a sleeve, significant bending were obtained from most of the models simulated. Large bending resulted from combined two patterns fiber weave models are achieved when maximum contraction and extension characteristics exhibit by both fiber weave patterns. Â
