The first robots are currently appearing on the consumer market. Initially they are targeted at rather simple applications such as entertainment and home convenience. For more complex areas, these robots will need to collaborate and interactively communicate with their human users, which requires appropriate man-machine interaction technologies and considerable cognitive abilities on the robot's side. Consumer acceptance will strongly depend on the integrated system. Thus, system integration and evaluation of the integrated system is becoming increasingly important. This paper describes our approach to construct a robotic assistance system. We present experience with an integrated technology demonstration and exposure of the integrated system to the public.
In modernen Prüffeldern zur Warenendkontrolle dienen halbleitergesteuerte Frequenzumformer zur Einstellung der Drehzahl. Diese Systeme verursachen erhebliche Störungen der Strom- und Spannungssignale. Aus diesen Signalen müssen alle elektrischen Kenngrößen berechnet werden. Eine besondere Bedeutung haben dabei die Frequenz und Phasenlage. In diesem Beitrag wird ein mathematischer Algorithmus vorgestellt, der zur Berechnung von Frequenz und Phasenlage bei guter Unterdrückung dieser Störungen eingesetzt werden kann.
