外文摘要：Walking on the water surface is an effective method for miniature robots to transport payloads with dramatically decreased interfacial drag.Current aquatic robots reported are generally actuated by a beam of focused light that can trigger asymmetrical deformation,enabling the directional movement through horizontal momentum transfer of photoinduced actuation force to the water.However,the operations are heavily dependent on manual manipulation of the focused light,making the long-term actuation and application of the aquatic robots in vast scenarios challenging.Herein,we developed a kind of water strider-inspired robot that can autonomously manage the motion on the water surface under solar irradiation,with their direction steerable by a magnetic field.The motion of this bioinspired robot on the water surface was achieved by the use of a solar cell panel as a driving module to enable propulsive motion based on the conversion of light-electric-mechanical energies.The superhydrophobic design of its leg surfaces enables the aquatic robots with weight-bearing and drag-reducing abilities.With the assistance of magnetic navigation,the bioinspired robot can continuously and controllably locomote to the oily spill floating on the water body and collect them with high efficiency.For further demonstration,the treatment of oil spills in a campus pool with high efficiency has also been achieved.This on-site oil-spill treating strategy,taking advantage of a home-made bioinspired robot actuated by natural sunlight under magnetic steering,shows great potential applications in water-body remediation.
