Underwater robot based on sea horse bionics

The invention belongs to the technical field of underwater bionic robots, and particularly relates to an underwater robot based on hippocampus bionics. Flexible steering and rapid propelling of the underwater robot are achieved, the posture adjusting hooking device at the tail is hooked to a seabed object or organism, the purpose of fixing the robot or saving energy is achieved, and the gravity center of the robot can be changed by adjusting the posture of the tail so that floating or diving of the robot can be controlled. The device comprises a differential steering device serving as a hippocampus head, a propelling device serving as a hippocampus chest and a posture adjusting hooking device serving as a hippocampus tail, the differential steering device is connected with the propelling device, and the propelling device is connected with the posture adjusting hooking device. 本发明属于水下仿生机器人技术领域，具体涉及一种基于海马仿生的水下机器人。本发明实现了水下机器人的灵活转向和快速推进，通过尾部的姿态调节钩附装置钩附到海底物体或生物上，达到固定机器人或是节省能源的目的，通过调节尾部的姿态还能实现机器人的重心变化从而控制机器人的上浮或是下潜
