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.

    本发明公开了一种仿生水下机器人及其驱动方法。现有水下机器人大多是以螺旋桨为驱动装置。本发明一种仿生水下机器人,包括驱动模块和推进模块。驱动模块设置在推进模块的头部。驱动模块包括驱动外壳和螺旋杆。螺旋杆的头端与驱动外壳的尾部转动连接。螺旋杆由动力元件驱动旋转。所述的推进模块包括依次排列相连的多个关节单元。相邻两个关节单元转动连接;关节单元的中部设置有条形通槽。螺旋杆穿过条形通槽。本发明通过一根螺旋杆的转动,就能够驱动多个关节单元的依次左右摆动,产生前进所需的行波,结构简单可靠。本发明采用仿生的方法,借鉴鱼类的驱动方式,更换了原始的螺旋桨的驱动方式,显著地提高了水下机器人的机械效率。
