The invention provides an underwater robotic fish gravity buoyancy center adjusting device and an underwater robotic fish, belongs to the technical field of underwater robots, and aims to solve the problems that in the prior art, the space utilization rate is not high, the structure is complex, the weight is large and shock resistance is poor are solved. A sliding rail set is fixedly mounted at the bottom of a static frame assembly; a synchronous belt is fixedly mounted at top, the synchronous belt is a strip-shaped synchronous belt of which the head and the tail are not connected and closed;the guide direction of the sliding rail set is consistent with the length direction of the synchronous belt, a weight assembly and a driving steering engine are arranged in an inner cavity of the static frame assembly and located between the synchronous belt and the sliding rail set, the bottom of the weight assembly is installed on the sliding rail set, the driving steering engine is fixedly installed on the weight assembly, the synchronous belt wheel is installed on the driving steering engine, and the synchronous belt wheel is meshed with the synchronous belt. And the driving steering engine drives a synchronous belt wheel so as to drive the heavy block assembly to slide along the guide direction of the slide rail group. The structure that the single synchronous belt is matched with thesynchronous belt wheel is adopted for adjusting the heavy buoyancy center, the space utilization rate is high, the structure is simple, the weight is light, and the anti-seismic property is good.
