In this paper, the design, implementation, and experiments of a weight-varied underwater are presented. The realization of the buoyancy engine is mainly accomplished by a unidirectional water pump and a three position five-way solenoid valve. The glider is designed to operate within 30 meters deep down to the water surface, and the detailed design process is introduced. The glider's equation of motion and dynamic features are presented and the steady-state solution is analyzed. The hydrodynamic coefficients are also calculated by using Computational Fluid Dynamics (CFD) method. Simulation and experimental results show the reliability and utility of the underwater glider.
