In flexible automation approach to batch or job-shop production the main emphasis has always been on the re-programmability of the elements of a manufacturing system. The assumption that lies behind this philosophy is that “system flexibility” can be achieved through (mainly) software flexibility and limited hardware flexibility. Modular robots introduce a new dimension to flexible automation in terms of hardware flexibility, when compared to conventional industrial robots, in terms of yielding individual global optimal arm geometries for each of the tasks at hand. The objective of our ongoing research in the area of “mechanical design of modular robots” is to develop an inventory of basic modular units, which will allow a user to configure the most suitable robot geometry for a task (or a set of tasks) at hand. Standardization of these units and minimization of the size of the inventory constitute the two main goals of this research. In this paper some of our research results on the conceptual design of a modular robot are presented. The individual modular robot units that are presented include: one degree-of-freedom (dof) main joints (rotary and prismatic types), one dof end effector joints (Yaw, Pitch and Roll types), links and connectors.

Urgency of the research. Automated workplaces are growing up in present, especially with implementation of industrial robots with feasibility of various dispositions, where safety and risk assessment is considered as most important issues. Target setting. The protection of workers must be at the first place, therefore safety and risk assessment at automated workplaces is most important problematic, which had presented in this article Actual scientific researches and issues analysis. Actual research is much more focused at standard workplaces without industrial robots. So, missing of information from the field of automated workplaces in connection with various dispositions can be considered as added value of article. Uninvestigated parts of general matters defining. Despite to lot of general safety instructions in this area, still is missed clear view only at automated workplace with industrial robots. The research objective. The aim of article is to provide general instructions directly from the field of automated workplaces The statement of basic materials. For success realization of automated workplace is good to have a helping hand and orientation requirements needed for risk assessment at the workplace. Conclusions. The results published in this article increase the awareness and information of such automated workplaces, together with industrial robots. In addition, presented general steps and requirements helps persons for better realization of these types of workplaces, where major role takes an industrial robot. Our proposed solution can be considered as relevant base for risk assessment such workplaces with safety fences or light barriers.
