Core Viewpoint - The article discusses the development of a new hybrid adhesion suction disc inspired by the lamprey, which overcomes challenges in amphibious environments and rough surfaces, enhancing the adaptability of robots in various conditions [2][5][10]. Group 1: Scientific Problem - The research addresses how negative pressure adhesion and mechanical locking can work together to overcome the limitations of adhesion on rough surfaces, aiming for stable and reversible universal adhesion [7]. - The study reveals the synergistic mechanism of "negative pressure adhesion + mechanical locking," inspired by the lamprey's mouth structure, and is published in the journal "Cyborg and Bionic Systems" [7]. Group 2: Performance Validation - The hybrid suction disc achieves a maximum adhesion force of 562.6 N in air and 590.7 N underwater, allowing it to lift objects over 850 times its own weight of 70 g [13]. - The introduction of the SMP layer enhances adhesion strength by 377% in air and 270% underwater compared to traditional suction methods, maintaining adhesion even on rough surfaces with a roughness of Ra 707 µm [13]. - The suction disc can maintain adhesion for up to 26.8 hours under a 5N load in air, a 195% improvement over the control group without SMP, and shows a 540% increase in underwater environments [13]. Group 3: Application Demonstration - The suction disc demonstrates versatility by successfully gripping objects across a wide weight range, from 0.01 g electronic chips to an 11.4 kg wooden tabletop, and adapts to various surface geometries [16][17]. - In underwater environments, the suction disc maintains stable adhesion on both smooth and complex surfaces, showcasing its adaptability [17]. - A notable demonstration involved the suction disc integrated with a robotic arm, successfully transitioning between air and water while maintaining reliable adhesion [18].
