Therefore, the device is switched between two different modes of driving in a common bat ray mode and spraying the bionic mantle, and the capability of flexibly turning in a narrow water area and propelling at a high speed in a wider water area is considered.
When the underwater robot is in a common bat ray robotic fish driving mode, the main control module controls the flexible bionic bat ray pectoral fins (4) to keep regular swinging and keep real-time rotation of the tail fins (5) at any time, when the underwater robot is in a bionic mantle jet state, the main control module controls the flexible bionic bat ray pectoral fins (4) to be furled and close to a base body, a bionic water inlet film starts to enter water, and relative jet frequency is kept to jet through a bionic nozzle, so that the bionic bat ray pectoral fins reach large acceleration in a short time.
