“…The diversity of natural ecological environments creates biodiversity, and nature provides researchers with a source of inspiration to solve major problems under complex conditions. In recent years, more and more studies have been conducted on biomimetic structures [55,56]. At the same time, due to the complex seabed topography and In the meantime, the dragging of the flexible hose while the DSMV is driving compacts the sediment at the ruts or flips the sediment on either side before it is redeposited [54], which can influence the physical and mechanical properties of the DSS, as shown in Figure 12.…”

“…Meanwhile, considering the strong adhesion properties of walking devices, res ers drew inspiration from burrowing animals [77], and bionic-based anti-adhesio chines were developed [78], which yielded successful outcomes. Wen-bo et al [56], Janarthanan et al [74] used the coupling Euler-Lagrange (CEL) method in ABAQUS 2020 software to numerically simulate tracks with different structural parameters, and they verified the impact of grouser characteristics on the ability to generate traction and displace soil. Sun et al [75] evaluated the impact of different parameters, i.e., different velocities, number of grousers, and composition of sediments by the coupling Euler-Lagrange method, where stress variation and disturbance data were obtained.…”

“…According to the DSS adhesion characteristics and discrete element method, a deep-sea sediment cutting model was established. A simulation experiment was performed on the designed grouser structure [56]. The experiment results demonstrated the efficient reduction in deep-sea sediment adhesion was achieved by the bionic grouser and such adhesion was minimized.…”

In response to the anticipated scarcity of terrestrial land resources in the coming years, the acquisition of marine mineral resources is imperative. This paper mainly summarizes the development of underwater collection and transportation equipment of polymetallic nodules in deep-sea mining. Firstly, the collection equipment is reviewed. The deep-sea mining vehicle (DSMV), as the key equipment of the collection equipment, mainly includes the collecting device and the walking device. The micro and macro properties of sediments have a great influence on the collection efficiency of mining vehicles. For the collecting device, the optimization of the jet head structure and the solid–liquid two-phase flow transport of the hose are discussed. The structure of the walking device restricts mining efficiency. The optimization of the geometric structure is studied, and the geometric passability and lightweight design of the walking device are discussed. Secondly, the core of transportation equipment is the lifting device composed of a riser and lifting pump. In order to explore the key factors affecting mineral transport, the lifting device is summarized, and the design optimization of the lifting pump and the factors affecting the stability of the riser are discussed. Then, the relationship between each device is discussed, and the overall coupling of the device is summarized. Finally, the existing problems and future research focus are summarized.
