“…Zhang et al developed three types of rolling robots with different mechanisms: impulse approach, gravity approach, and ballistic approach [17]. In addition to these methods, fluidic systems have also been adopted to drive the robots [18,19]. Gong et al developed a unique mechanism based on the peristaltic motion of an elastomeric stator and a rotor [20].…”

Rolling motions have been observed in many animals and insects. In the previous fluidic rolling system, a deformed chamber and long cables were imperative to drive the soft rolling actuators, which required high pressure and a sophisticated controlling strategy. In this study, we propose a soft fluidic roller using a simple structure composed of a bendable and twistable electrohydrodynamic (EHD) pump and a layer of natural latex. To realize the rolling motion, we first optimized the electrode and channel height of the EHD pumps using different patterns and designs. We also examined the output power, efficiency, pressure loss, bending, and twisting performance. Subsequently, the optimized electrodes and channel height were selected to design the power source of the EHD roller. This roller was lightweight (0.7 g) with an amount of liquid (0.6 g). This EHD robot can roll as the EHD fluid oscillates under a duty-controlled voltage realized using a high-voltage circuit. Next, we investigated the influence of frictional forces on rolling performance. Finally, the rolling motion in the liquid was demonstrated. This study extends the EHD pumps to independent soft actuators integrated with a soft power source.
