This paper outlines the current state of the virtual prototyping program using ADAMS under development at GreyPilgrim Incorporated. This program is being developed in order to provide analysis in the mechanical design of cable driven hyperredundant flexible manipulators, referred to as EMMAs (Easily Manipulated Mechanical Arms). A diagram of a typical EMMA manipulator can be seen in Figure 1 be...

We have constructed and operated a nanoscale linear motor powered by a single metal nanocrystal ram sandwiched between mechanical lever arms. Low-level electrical voltages applied to the carbon nanotube lever arms cause the nanocrystal to grow or shrink in a controlled manner. The length of the ram is adjustable from 0 to more than 150 nm, with extension speeds exceeding 1900 nm/s. The thermody...

In this work, an array of electromechanical systems driven by electrical line Fitzhugh-Nagumo neurons is analyzed. It shown that a single system can display different dynamical behaviors such as and multiple pulse generation, transient permanent chaos, antimonotonicity according to the parameters. case constituted series coupled discrete neurons, numerical simulation shows action potential flow...

Micro-electro-mechanical systems (MEMs) are Combination of electrical and mechanical components in Micron dimensions. In recent years, holding, actuating methods and handling of MEMs components such as microgripper, microsensors and etc. have been deeply studied. Microgrippers for handling, positioning and assembling of micro components are very useful so that for clamping need actuation create...

Although the kinematics and dynamics of overarm throws, such as baseball pitching, have been studied extensively, the relations between these measures remain largely unknown. This review uses a three-dimensional analysis to characterize the mechanical basis of skilled overarm throws by focusing on how each joint angular acceleration is produced by the muscle torques, gravity torques, and veloci...

The skilled nursing facility benefit under Medicare has been difficult to administer because its intent has been subject to misinterpretation. This article describes the series of legislative and administrative actions taken to align the benefit's use with its intent. Data are presented to show the changes in utilization and program expenditures in response to the actions taken. The 1988 clarif...

We determined muscle attachment points for the index, middle, ring and little fingers in an OpenSim upper-extremity model. Attachment points were selected to match both experimentally measured locations and mechanical function (moment arms). Although experimental measurements of finger muscle attachments have been made, models differ from specimens in many respects such as bone segment ratio, j...
