Bionic underwater robot and driving method thereof

Abstract

The invention discloses a bionic underwater robot and a driving method thereof. Existing underwater robots mostly take propellers as driving devices. The invention discloses the bionic underwater robot. The bionic underwater robot comprises a driving module and a propelling module. The driving module is arranged at the head of the propelling module. The driving module comprises a driving shell anda screw rod. And the head end of the screw rod is rotatably connected with the tail part of the driving shell. The screw rod is driven by a power element to rotate. The propelling module comprises aplurality of joint units which are sequentially arranged and connected. Every two adjacent joint units are rotatably connected. A strip-shaped through groove is formed in the middle of each joint unit. And the screw rod penetrates through the strip-shaped through groove. Through rotation of one screw rod, the multiple joint units can be driven to swing left and right in sequence, traveling waves needed by advancing are generated, and the structure is simple and reliable. According to the bionic underwater robot, a bionic method is adopted, a fish driving mode is used for reference, an originalpropeller driving mode is replaced, and the mechanical efficiency of the underwater robot is remarkably improved.

Description

technical field [0001] The invention belongs to the field of underwater robots, and in particular relates to a bionic underwater robot and a driving method thereof. Background technique [0002] At present, there are three main aspects of research on underwater robots at home and abroad: remote, deep-sea and intelligent. However, there is no in-depth research and improvement on the driving method. Most of the underwater robots seen so far use the propeller as the driving device, and obtain high thrust by rotating the propeller. Between 50% and 75%. In addition, due to the inherent high-speed rotation of the propeller, the noise generated by it has caused disturbance to the marine ecosystem, and the sharp propeller blades will also cause direct damage to marine life. In order to improve the driving efficiency and reduce the negative impact on the marine ecosystem, a bionic underwater robot was proposed, which borrowed the driving method of fish to achieve the above goals. ...
