Abstract: This paper addresses issues existing in traditional underwater robots during marine resource surveys， such as low propulsion efficiency， poor terrain adaptability， and insufficient sample analysis accuracy. To solve these problems， this paper proposes a bionic underwater robot design scheme based on the biological form of anglerfish， which integrates plasma superconducting magnetohydrodynamic propulsion， multi-physical field detection， and bionic structure design. This scheme provides a strong reference for underwater marine research.

Key words: bionic underwater anglerfish robot, underwater detection, magnetohydrodynamic propulsion
