“…In these cases, impacts that do not break through the surface are particularly relevant to the study of water-walking mechanisms (Yang et al 2016). Inspired by water-walking insects, numerous biomimetic robots have been proposed for use in autonomous environmental exploration and monitoring (Bush & Hu 2006;Hu et al 2010;Yuan & Cho 2012;Zhao et al 2012;Koh et al 2015;Yang et al 2016;Chen et al 2018b;Kwak & Bae 2018). Dynamic particle motion with capillary effects is also fundamental to a number of industrial processes including self-assembly of particles at interfaces (Whitesides & Boncheva 2002;Whitesides & Grzybowski 2002), wet scrubbing and deposition for removal of particulates from gases (Jaworek et al 2006;Wang, Song & Yao 2015), mineral flotation for material processing (Ueda et al 2010;Liu, Evans & He 2016) and particle deposition techniques for rapid manufacturing (Haley, Schoenung & Lavernia 2019).…”

“…The center of gravity of the robot is carefully designed to allow the robot to jump on the surface continuously and smoothly. The fabricated robot weighs approximately 10.2 g and can continuously jump on water with a maximum leap height and length of 120 and 410 mm, respectively [ 47 ].…”

“…For micro jumping robots, the application of new materials is the biggest difference with the traditional structures of jumping legs [ 2 , 50 – 52 ], and this provides a new idea for the design of rigid-flexible coupling bionic structures. The biggest contribution of the fabricated water-jumping robot [ 47 ] and biowater strider jumping robot [ 53 ] is to achieve a steady takeoff on the water surface. All the above researches are to finally make the jumping robots have good jumping performance, which includes jumping height (obstacle avoidance ability) and jumping distance (escape distance).…”

A bioinspired jumping robot has a strong ability to overcome obstacles. It can be applied to the occasion with complex and changeable environment, such as detection of planet surface, postdisaster relief, and military reconnaissance. So the bioinspired jumping robot has broad application prospect. The jumping process of the robot can be divided into three stages: takeoff, air posture adjustment, and landing buffer. The motivation of this review is to investigate the research results of the most published bioinspired jumping robots for these three stages. Then, the movement performance of the bioinspired jumping robots is analyzed and compared quantitatively. Then, the limitation of the research on bioinspired jumping robots is discussed, such as the research on the mechanism of biological motion is not thorough enough, the research method about structural design, material applications, and control are still traditional, and energy utilization is low, which make the robots far from practical applications. Finally, the development trend is summarized. This review provides a reference for further research of bioinspired jumping robots.

superhydrophobic materials have been reported. [12] However, most of these materials make use of petroleum derivatives and fluorinated compounds, [13] as well as textured inorganic materials, [14] which serve as substrates for surface chemical functionalization. These materials are not inherently biodegradable and thus pose a challenge in terms of environmental impact and recyclability. Especially longchain fluorinated compounds, which are used often to obtain liquid repellency, are difficult to degrade and tend to bioaccumulate. [15,16] Furthermore, even if these substances degrade after a prolonged period, some of their by-products are known to be toxic, such as perfluorooctanoic acid [17] and perfluorooctanesulfonate. [18] Recent studies have reported the use of more sustainable methods and materials to obtain the self-cleaning effect. These include the use of biodegradable polymers and natural materials, [19] waterborne spray approaches, [20] alcoholic solvent environment, [21] silicone-based biocompatible materials, [22] reactive polymeric materials, [23] fluorine-free substances, [24][25][26] cellulose-based, [27] and natural wax-based material compositions. [28,29] The use of the latter two materials (cellulose and wax) is inspired from the fact that they are the main constituents of a broad selection of plants, including the well-known Lotus leaf. [30] Cellulose is the material that mainly constitutes the substrate and is responsible for the leaf's mechanical properties and microroughness (the latter in the form of macropapillae) in a wide range of plants. On the other hand, the wax nanocrystals cover the microtopography and are responsible for the superhydrophobicity, bothThe development of fully organic (cellulose/wax based), biodegradable, and hierarchically textured superhydrophobic material, inspired by natural, selfcleaning plants, like the Lotus leaf is reported. The developed material can reproduce in a controllable and artificial manner the chemical composition and material properties of these natural surfaces. At the same time, the fabrication protocol described here enables realization of properties beyond the ones found in the natural leaves, by allowing facile tuning of the topographical and mechanical properties. The surface topography consists of a micropillar structure assembly with, to the best of the authors' knowledge, the highest to date reported aspect ratio (7.6) for cellulose materials. Additionally, control and tunability of the material's mechanical properties are also demonstrated, which is rendered softer (down to 227 MPa Young's modulus from 997 MPa base value) by adding glycerol as a natural plasticizer. Finally, the self-cleaning properties are demonstrated and the biodegradability of the material is evaluated in a period of ≈3 months, which confirms full biodegradation. Additionally, water drop and jet impact, and folding tests demonstrate that the material can reasonably sustain its wettability properties. Such a truly bioinspired and biodegradable material system could fin...
