Yet the utilization of participatory processes can help to overcome this gap. In a practical example in the watershed of the Danube River and its contributing streams in Germany,we aimed to solve questions about the value of participatory modeling as a method to bridge the gap linked to flood polder planning and a relocation of a dike for protection against high floods(centennial floods and rarer). Local communities, citizen initiatives, and nongovernmental environmental organizations joined together for round table discussions initiated by the water management authorities. A participatory modeling process enabled these diverse stakeholders to engage with the experts who built the groundwater models for the planning process. As part of this study, two case studies are presented. In the first example, neutral mediators assisted the round table ‘‘Flood Polder Katzau(Danube)'' in order to cultivate mutual trust and understanding between the authorities and the former opponents of the project. This process is still ongoing,challenged by long-term planning and the more immediate obstacle of current political changes. The second case studyis located on the river Alz, a tributary of the river Inn,which flows into the Danube, where the relocation of a dike was planned. This article demonstrates how participatory modeling contributes to bridging the gap between a local resident's risk perception and real action in the case of flood preparedness.展开更多

Different from existing methods, the proposed control approach defines actions with the principle of "perception-planning-action" inspired by human intelligence. Character extraction is used to divide the perception input into different modes. Different control modes are built by combining different control methods for the linear velocity and angular velocity. Based on production rules, the motion control is realized by connecting different perceptions to the corresponding control mode. Simulation and real experiments are conducted with the middle-sized robot Frontier-I, and the proposed method is compared with a proportional-integral-derivative (PID) control method to display its feasibility and performance. The results show that the multi-modal action control method can make robots react rapidly in a dynamic environment.展开更多
