Haptic refers to feedback of a physical signal to a human user through touch. A haptic system realizes this feedback. In most of the applications today, the physical signal refers to force but not necessary. Virtual environment haptic systems refers to the situation where the force to be feedback from the objects in a virtual environment or computer. Virtual environment haptic robotic systems are...
In this paper, two control strategies are developed to control the piezoelectric inertia-friction actuator (PIFA) systems with a great attention to counter for the thermal effect. The first strategy is to use two controllers: one is the main controller (used to control the actuation) and the other is the auxiliary controller to adjust the contact pressure (used to compensate the thermal effect). The...
This paper provides a classification of in-pipe robots or robotic mechanisms in literature with the help of axiomatic design theory (ADT). The existing classification of these designs focuses on either their mobility or contact of the robot with the pipe inner surface. Such classification fails to provide a framework to guide the design of such robots. In this paper, we first propose a new approach...
Growing interest in assessing the reliability of microelectromechanical systems has created a need for the development of microinstruments to interrogate MEMS behavior under diverse conditions. This paper describes the design and testing of a microinstrument for in-situ reliability studies of contacting surfaces in MEMS. Time-dependent changes in the structure, chemistry and electrical properties...
Endothelial cell–cell contact via VE-cadherin plays an important role in regulating numerous cell functions, including proliferation. However, using different experimental approaches to manipulate cell–cell contact, investigators have observed both inhibition and stimulation of proliferation depending on the adhesive context. In this study, we used micropatterned wells combined with active positioning...
