The invention belongs to the field of underwater robots, and aims to solve the problems that an underwater robot buoyancy adjusting device is complex in structure and large in energy consumption. Theinvention provides an underwater robot high-precision buoyancy adjusting device. The device comprises a driving device, a gear pump, an electromagnetic valve, a flow meter and an inner oil bag systemthat are installed in a seal shell, and an outer oil bag installed in a permeable housing. An output shaft of the driving device is connected to an input shaft of the gear pump; the flow meter is usedfor connecting the inner oil bag system and the gear pump; the gear pump is used for communicating the flow meter and the electromagnetic valve, and the electromagnetic valve is connected to the outer oil bag; in a working state, oil in the inner oil bag system enters the outer oil bag through the flow meter when the gear pump rotates forwards and the electromagnetic valve is powered on, or oil in the outer oil bag enters the inner oil bag system through the flow meter when the gear pump rotates reversely and the electromagnetic valve is powered on. The buoyancy adjusting device has the beneficial effects that: the direct-current motor direct-driven gear pump rotates to achieve precise volume change of the inner oil bag and the outer oil bag, and high-precision and low-energy consumptionbuoyancy adjustment is achieved.
