    An elaborate study executed in the direction of exploring energy saving potential shows that more than 20% of electrical energy used in industry is used for pump systems. Experts calculate that more than 30% of this energy can be saved by improving control and diagnosis for pump systems. Unfortunately, the application ratio of such system is small and consequently a large demand for such technological advanced systems can still be observed in the pump industry. Because of this reason and still growing demand of saving energy in industry, two Universities in Germany and Switzerland together with leading German pump manufacturer decided to join their knowledge and skill to work on the project called "Smart Pump". This paper presents one of the first results of this project, which goal is the development of future control methods and diagnosis systems for intelligent pumps.Szczeg贸艂owa analiza, przeprowadzona w kierunku poszukiwania potencja艂u oszcz臋dno艣ci energii, wykazuje, 偶e ponad 20% energii elektrycznej u偶ywanej w przemy艣le, jest wykorzystane przez systemy pomp. Eksperci szacuj膮, 偶e ponad 30% tej energii mo偶e by膰 zaoszcz臋dzone poprzez udoskonalenie kontroli oraz diagnostyki w systemach wykorzystuj膮cych pompy. Niestety, wsp贸艂czynnik zastosowania takich system贸w jest niewielki, dlatego konsekwentnie mo偶na zaobserwowa膰 wzrost zainteresowania zaawansowanymi technicznie systemami kontrolno-diagnostycznymi w przemy艣le pompowym. Ten w艂a艣nie czynnik oraz ci膮gle rosn膮ce zapotrzebowania na oszcz臋dzanie energii, by艂y powodem dzi臋ki kt贸remu dwa uniwersytety w Niemczech oraz Szwajcarii, razem z czo艂owym niemieckim producentem pomp, zdecydowali po艂膮czy膰 swoj膮 wiedz臋 i umiej臋tno艣ci w celu pracy nad projektem zwanym "Inteligentne pompy". Poni偶szy artyku艂 przedstawia jeden z pierwszych etap贸w danego projektu, kt贸rego g艂贸wnym celem jest rozw贸j nowoczesnych metod kontroli oraz diagnostyki w systemach pomp

    Actuated Bivalve Robot -- Study of the Burrowing Locomotion in Sediment

    This paper presents the design and control of an actuated bivalve robot, which has been developed to study the burrowing locomotion of bivalves in sediment. The setup consists of a tank filled with sand and water, plastic models of bivalve shells capable of expelling water and an external actuation mechanism simulating the rocking burrowing motion typically used by these animals. The realistic shell shapes have been realized using three-dimensional plotting techniques allowing testing influences of different shell shapes and surface structures (sculptures) on the burrowing efficiency. Based on the experimental setup, the burrowing process has been reproduced. The results show that this setup can be used to identify correlations in the burrowing process. Further experimental work will investigate the influence of factors such as shell shape and sculpture or the motion sequence on the burrowing performance.
