Research on Key Technologies for Water Intelligent Rescue Robots: Design and Implementation of Bionic Octopus Tentacle Rescue Mechanisms

In this study, a bionic octopus tentacle rescue mechanism is designed to address the bottleneck of the adaptability and grasping ability of traditional water rescue equipment (robotic arm and winch mechanism) in the complex water environment. Through the modular design of the robot structure (asymmetric buoyancy chamber, variable pitch propeller), the development of multi-joint flexible mechanical structure and the optimisation of the power system (vector control of permanent magnet synchronous motor), the stable operation and accurate grasping of the rescue equipment in turbulence and obstacle scenarios are realised. The experiment verifies the effectiveness of the bionic mechanism in complex environments and provides a new path for water rescue technology.
