A novel concept called gesture-changeable under-actuated (GCUA) function is proposed to improve the dexterities of traditional under-actuated hands and reduce the control difficulties of dexterous hands. Based on the GCUA function, a new humanoid robot hand, GCUA Hand is designed and manufactured. The GCUA Hand can grasp different objects self-adaptively and change its initial gesture dexterous...

This study compared control delays computed by HCM (using HCS software), Synchro, PASSER II, PASSER IV, and CORSIM for an urban arterial. Base and optimized conditions were studied. In the base condition, the existing signal settings and traffic volumes were modeled in HCS and Synchro under three scenarios: actuated-coordinated, actuated-uncoordinated and pre-timed traffic controller. For the b...

Given a linear system, we consider the expected energy to move from the origin to a uniformly random point on the unit sphere as a function of the set of actuated variables. We show this function is not necessarily supermodular, correcting some claims in the existing literature.

A wavelengthand bandwidthtunable filter with microelectromechanical-system (MEMS)actuated waveguides is first demonstrated on a silicon-based microdisk resonator. Integrated microheaters enabled wavelength tuning up to 125GHz. Bandwidth can be tuned from 12.0 to 41.2GHz by coupling control. © 2005 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (140.4780) Optical re...

We study the existence and stability of periodic solutions of a canonical mass-spring model of electrostatically actuated micro-electro-mechanical system (MEMS) by means of classical topological techniques like a-priori bounds, Leray-Schauder degree and topological index. A saddle-node bifurcation is revealed, in analogy with the autonomous case.
