Data obtained in wave-tank experiments usually exhibit considerable scatter, which seems to arise mostly from inaccurate movement of paddle of wave-maker or its unintensional change among experimental runs. By using stepping motor, ball-screw. linear-slider, and personal computor, we constructed a digitally controlled wave-maker for a small-scale laboratory water tank. The wave-maker is controlled unidirectionally and no feedback system is applied in the present stage. Reproducibility of generated wave forms is remarkably good even without feedback system. Demonstration is made for the successful application to solitary wave experiments.
