Underwater robot

The underwater robot comprises a machine frame and four pairs of propellers which are arranged in a bilateral symmetry mode, the four corners of the machine frame are provided with two pairs of propellers, the longitudinal center of the machine frame is provided with two pairs of propellers, and each pair of propellers is oppositely arranged at the longitudinal left end and the longitudinal right end of the machine frame. And in each pair of propellers, one propeller is a positive propeller, and the other propeller is a negative propeller. Due to the fact that the four pairs of propellers are symmetrically arranged on the structure, two pairs of propellers are arranged at the four corners, and the other two pairs of propellers are arranged in the longitudinal center, balance is good, and control is easy; and each pair of propellers adopts positive and negative propeller pairing, so that the spinning problem caused by propellers is eliminated, and the work is stable and reliable. 本实用新型公开了一种水下机器人，包括左右对称设置的机架和四对
