According to news reporting out of Harbin, People's Republic of China, by NewsRx editors, research stated, "Using robots to detect Marine structures is very important for maintaining the safety of Marine structures. This paper pres ents an underwater inspection robot specifically engineered for the assessment o f underwater structures." Financial supporters for this research include National Key Research & Development Program of China, Natural Science Foundation of Heilongjiang Provinc e. Our news journalists obtained a quote from the research from Harbin Engineering University, "The integration of reliable adhesion technology is identified as a critical factor in the development of such robots. The vortex suction cup, emplo yed by the robot as its primary adhesion mechanism, outperforms traditional adhe sion methods by enabling non-contact attachment while consuming less power. As t he vortex suction cup is the core component of the underwater inspection robot, this study comprehensively investigates how variations in the vortex suction cup 's structural and operational parameters influence its adhesion performance, mea sured from an energy efficiency ratio perspective. Initially, we delineate the v ortex suction cup's design and succinctly explicate the mechanism underpinning t he generation of negative pressure. Subsequently, we establish an evaluative par ameter, the energy efficiency ratio (eta = F/P), that is, the adsorption force o btained per watt of power consumption of the suction cup, serving as a metric fo r the adhesion performance. By simulating the structural and operational paramet ers of the suction cup, we extract the corresponding adhesion force, torque, and energy efficiency ratio. Lastly, we construct an experimental apparatus to meas ure the suction cup's adhesion force and output torque, validating the veracity of the simulated outcomes. Our simulation and experimental findings indicate that increasing the height of the suction cup housing enhances the adsorption force , however, this simultaneously diminishes its energy efficiency ratio performanc e. Likewise, an increase in the chamber inner radius amplifies the adhesion forc e, and the energy efficiency ratio commensurately increases. Augmenting the radi us of the negative pressure effect board improves the adhesion force, decreases the required torque, and consequently amplifies the energy efficiency ratio. The suction cup's adhesion force and required torque display a direct relationship with its speed, but the energy efficiency ratio is minimally affected by speed. When the distance is close (h <4 mm), changes in the adhes ion gap profoundly impact the suction cup's torque and energy efficiency ratio."
