The Wufeng Formation-Longmaxi Formation (O3w-S1l1) black shales within the Yangtze foreland basin (South China) hold significant potential as unconventional oil and gas resources.However, several challenges, including sluggish sedimentation rates, thin sedimentary layers, and notable homogeneity, hinder a comprehensive grasp of the organic matter e
Underwater snake robots have received attention because of their unique mechanics and locomotion patterns.Given their highly redundant degrees of freedom, designing an energy-efficient gait has been a main challenge for the 5326058hx long-term autonomy of underwater snake robots.We propose a gait design method for an underwater snake robot based on
