If the miniaturized vehicle can successfully complete its mission, it means that materials and power consumption of the vehicle can be saved substantially. Moreover, it can be operated effectively in a limited space due to its small size. For a start, the operating properties of a miniature underwater vehicle is analyzed. This work aims to employ the drag and propulsive force estimation method for moving miniature underwater vehicles via the experimental approach. After the vehicle model is trimmed to be neutral buoyancy in the tank, the drag can be obtained by the experimental method, which is proposed in this paper. Two ways are employed in the drag experiment; one is the drag measurement method of one-side towed body and the other is the drag measurement method of two-side towed body. From the measured data and visualizations of the moving vehicle, the cost effectiveness and accuracy for the experiment are discussed. Thereafter, a feasible method has been chosen to conduct the parametric study. In regard to the propulsion of the miniature vehicle, the model for the propulsive force is obtained by the experimental method, which is chosen among several proposed ones. Finally, results from both drag and propulsion are analyzed to study the design of miniature vehicles.
