This paper addresses modeling of requirements in the eld of high dynamic parallel robots. Parallel robots are mechatronic, mass customization products. Every task at each customer is unique. Thus, the need for a domain integrating method that supports the development of modular systems was the main motivation for this work. Requirements are seen as the core of a successful product development. All steps of the development process and every subsystem should support the initial goals. A requirements model on the basis of the Systems Modeling Language (SysML) is shown. It integrates, visualizes and documents several different model elements. A classi cation of requirements and relations (both qualitative and quantitative) helps detecting goal con icts and estimating change impact. Assigning certainty and change probability to the elements gives directions how to decompose into modules and where to integrate change propagation blocker or exible modules
