Robots should perform decontamination tasks as independently as possible in environments that are hostile to humans, e.g. in the remediation of contaminated sites or in the dismantling of nuclear facilities and the decontamination of power plant components – with the aim of allowing humans to stay out of the danger zone. This vision was at the beginning of ROBDEKON. Now, the first, four-year funding phase of the competence center has been completed and various systems waiting for their evaluation in the field have been developed. These systems are able to measure contamination, handle hazardous substances, or autonomously remove contaminated layers of soil.
