The design of a mobile microrobot based on standing and travelling waves is proposed and analysed in this paper. Numerical modelling based on the finite element method is performed to find the resonant frequencies and modal shapes of a microrobot, and to calculate the trajectories of the upper pointsʹ movements under an excitation scheme. Geometric Path‐Planning Algorithms for a piezoelectric hemispheric microrobot and an experimental study of this are presented in this paper.

Part Two of this article deals with problems related to land valuation. For that purpose, a site of 6.89 ares located in Švitrigailos Street XX, Vilnius, was selected as the research object and appraised using three approaches: the sales comparison approach, the MAMVA method and the mass valuation approach. Peculiarities of these methods in land valuation were reviewed and the recommendations were provided for land valuation for taxation purposes applicable in a new Model for Lithuanian Real Property Taxation System.
