Abstract

The invention provides a bionic fishtail underwater robot which comprises a shell, a propelling mechanism, a posture adjusting mechanism and a control system, wherein the propelling mechanism and theposture adjusting mechanism are both arranged on the shell. The propelling mechanism comprises an installation plate, a torsion spring string with one end fixedly connected to the installation plate,a tail fin fixedly connected to the other end of the torsion spring string, an elastic tail body wrapping the torsion spring string, and a first power assembly used for driving the installation plateto swing. The posture adjusting mechanism comprises pectoral fins arranged on the two opposite sides of the shell, a dorsal fin arranged on the top of the shell and a second power assembly used for driving the pectoral fins and the dorsal fin to swing. The first power assembly and the second power assembly are electrically connected to the control system. Compared with the prior art, the underwater robot can simulate the swimming mode of marine animals and fishes by using the torque spring string, so that the swimming speed and efficiency of the fishes are obtained; power resources are fully utilized, and high-efficiency torque output is achieved; and the propelling mode has the advantage of being low in noise.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a bionic fishtail underwater robot. Background technique [0002] With the advancement of the national marine strategy, underwater robots have been widely used in military and civilian fields such as marine biological research, submarine resource detection, and marine military missions. Traditional underwater robots generally use propellers as a driving method, so that underwater robots can move in water. [0003] However, the traditional underwater robot based on the propeller propulsion mechanism has the following disadvantages and deficiencies: high energy consumption rate and low energy utilization rate, fixed blade curvature is the main reason for low efficiency, and will generate large noise and tail eddy. [0004] Therefore, there is an urgent need for an underwater robot with high performance and low noise. Contents of the invention [0005] The purpos...
