In this paper we observe the difficulties one can face when using different MPLs (Motion Planning Library) in a single application, and propose a new conception and a language which goal is to solve these problems. The idea is to present an interface between robot programming instruments and MPLs. Our goal is to provide a powerful tool for developers of software approaches for programming industrial robots that would allow an easy combination of different MPLs in one application. In addition the proposed conception hides the inner structure of libraries and eliminates the need to investigate algorithms before applying. That would increase the speed and the quality of the newly developed software systems.
