Abstract
Abstract A non-contact transport method using near-field acoustic levitation has been studied. In this research, the levitated object is transported by multiple stators in steps. This transport method requires a large number of stators, but it has the advantage of precisef positioning because the levitated object is stopped and held on each stator. In addition, by arranging stators in two dimensions, transportation in two-dimensional direction is realized, but stable operation is not obtained, such as unintended rotation in transportation. Through experiments and analysis, we clarified under what conditions the transported object rotates.
