Safe robot development is based on three factors: safety,performanceandeconomy. Currently however, only two properties can be maximized at once, which is why an alternative for maximizing all three factors has been worked on. In particular the topic of safe environment has been discussed, where sensors from individual robots will be relocated in the environment. A sensor thus monitors more than one robot, which leads to an increase in efficiency. Due to the novelty, technical and legal requirements of such a system have first been clarified. The re- quiredcomponentshave thenbeendetermined inor- der to plan a possible implementation. Finally an adapted concept for the Digital Factory of the UAS Technikum Vienna showed the feasibility of a safety- certifiable environmental sensor system. 1. Introduction The fourth industrial revolution is characterized by a flexible production of individual products, which will be ensured by interconnected smart com- ponents and robots [5]. However, robots of the third industrial revolution are not flexible enough for this task due to their stationary location. For this rea- son they are accompanied by mobile robots, which enable a higher production flexibility [3]. These robots will further relieve human work forces from monotonous work allowing them to work on more complex tasks [2]. A combination of human flexi- bility and robot repeatability thus represents the fu- ture of production, whereby safe cooperation must be guaranteed. Furthermore, appropriate changes in intelligentproductionsystemsare recommendeddue to an expected compound annual growth of 23.1% between 2018 and 2023 in the area covering tech- nologiesof the fourth industrial revolution [4]. 2.CurrentSolutionsandMotivation Development of industrial and mobile robots is based on three factors as shown in Figure 1. How- ever, current conceptsonlymanage tomaximize two of the three properties at once. As safety should never be neglected in a factory, there are two possi- bleconfigurations: Eitherexpensivesystemsorcost- efficient approacheswithweakerperformance [1]. Figure1.

However, applicable documents differ in each case and experts (e.g. TU¨V AUSTRIA, labour inspectorate, etc.) should be consulted for support. Afterwards suitable components of the three identi- fiedkeyelementsofsensorsystems,processingunits and communication modules have to be researched and compared.
