Abstract
En 中文
The ability of a robot to reason, act, and adapt depends on how its sensory, actuation, and control systems; geometry; and materials interact with the physical world (1, 2). This interplay becomes nuanced at small scales, at which forces such as adhesion and surface tension dominate inertial forces. Many small organisms bear structures that exploit the physics of their environments. For example, jellyfish pulse their bell-shaped bodies to create vortex rings that enhance mobility (3), and microscopic paramecia propel through water by beating rows of hairlike microstructures (4). Increasingly, roboticists view environments as enabling rather than restricting design capabilities. On page 811 of this issue, Ortega-Jimenez et al. (5) report a water-walking robot inspired by the Rhagovelia ripple bug. This insect passively deploys fanlike appendages on its legs as they cross the air-water interface to maneuver in turbulent waters. The bio-inspired design demonstrates a compelling strategy for interfacially mediated autonomous robots.
