▎ 摘　　要

NOVELTY - The underwater robot has a driving mechanism which comprises a side moving driving mechanism (3) and a lifting driving mechanism (4). The housing (1) is provided with a driving chamber (12). A main driving motor drives rotating ring (31) to rotate. The wall of the driving chamber is provided with two radial through holes. Each radial through hole is provided with a conductive carbon needle. The outer side of each conductive carbon needle end passes through a respective one of the radial through hole and propped against the respective one of the annular graphene carbon brush. The inner side end of each conductive needle carbon connected through leading wire and power supply in the housing. The outer wall of the drive chamber is circular, and the rotating ring slides directly around the outer wall of the drive chamber. USE - Underwater robot powered by graphene carbon brush. ADVANTAGE - The power direction generated by the Lifting DRIVING mechanism is fixed relative to the housing. The power direction generated by the side moving driving mechanism is variable with respect to the housing. The two powers can be combined to drive the housing at any angle. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the underwater robot.
