Hydraulically amplified self-healing electrostatic (HASEL) actuators are known for their muscle-like activation, rapid operation, and direct electrical control, making them highly versatile use in soft robotics. While current methods enhancing HASEL actuator performance largely emphasize material innovation, our approach offers an additional architectural strategy. In this study, we introduce a novel hydraulically rigidity-adaptive (HARIE) designed to significantly enhance while maintaining controllability by elucidating the underlying issues of pull-in instability. Our experimental results indicate that HARIE achieves significant improvement, with over 200% increase angular output consistently strong torque compared flexible electrodes. Notably, maximum step is 21.8°/kV, approximately one third rigid electrodes (62.3°/kV), suggesting smoother motion control. The actuator's effectiveness further demonstrated practical applications; it successfully grasps orange weighing 15.2 g delicate dandelion. Additionally, precise targeting capability evidenced its ability manipulate laser induce heat accumulation, leading balloon's breakdown, thereby showcasing high level controllability. method mitigates negative impacts suboptimal materials demonstrates potential enhancement when combined superior materials.
