[Purposes]In view of the particularity and uncertainty of underwater environment,an underwa-ter search and rescue robot was designed to improve the rescue efficiency,ensure the safety of rescuers and reduce drowning accidents.[Methods]The robot integrates high-precision sensor,mechanical arm,six-propeller power system,three-dimensional sonar and linear active disturbance rejection controller,and realizes detailed scanning,rapid positioning,accurate rescue and efficient path cruise of underwater environment.[Findings]The finite element analysis of the manipulator was carried out by using Solid-works three-dimensional software to ensure its stability and durability under various working conditions.[Conclusions]This study not only improves the technical level of underwater rescue,but also provides valuable experience and technical support for the intelligent development of related fields.
