Underwater robot propelling device and underwater robot

The invention relates to the technical field of robots, in particular to an underwater robot propelling device and an underwater robot. The underwater robot propelling device comprises a control unit, a power plate type propelling mechanism and a power control mechanism, wherein the control unit is contained in a power chamber of the underwater robot propelling device and is suitable for receiving remote control signals; the power plate type propelling mechanism comprises two power plates suitable for conducting front-and-back reciprocating motion on water to generate propelling force; the power control mechanism is located in the power chamber and connected with the control unit and the power plate type propelling mechanism and is suitable for receiving control signals sent by the control unit to drive the two power plates of the power plate type propelling mechanism to move, that is to say, the power control mechanism controls the propelling speed of the power plate type propelling mechanism. 本发明涉及机器人技术领域，尤
