The invention belongs to the field of underwater robots, and in order to solve the problems that an underwater robot buoyancy adjusting device is complex in structure and poor in reliability, the invention provides an underwater robot bidirectional buoyancy adjusting device. The device comprises a driving device, a bidirectional gear pump, an electromagnetic valve and an inner oil cylinder systemthat are installed in a seal shell, and an outer oil bag installed in a water permeable housing. An output shaft of the driving device is connected to an input shaft of the bidirectional gear pump, and the driving device and the bidirectional gear pump are both arranged on an oil pump connecting flange; a first oil port of the bidirectional gear pump is connected to the inner oil cylinder system,and a second oil port of the bidirectional gear pump is connected to the outer oil bag through the electromagnetic valve. The device has the beneficial effects that: a direct-current motor directly drives the bidirectional gear pump to rotate forwards and backwards through a coupler to achieve expansion or contraction of the outer oil bag, then the buoyancy of the underwater robot is increased orreduced, and the whole device is simple in structure, stable, reliable and high in mechanical efficiency.
