This chapter focuses on the mobility analysis of spatial parallel manipulators. It first develops an analytical methodology to investigate the instantaneous degree of freedom (DOF) of the end-effector of a parallel manipulator. And then, the instantaneous controllability of the end-effector is discussed from the viewpoint of the possible actuation schemes which will be especially useful for the...

Abstract As a critical step to integrate micro-nano electronic components on the soft substrate, transfer printing allows facile fabrication of flexible electronics. The key successful process is modulate interfacial adhesion strength at stamp/device interface. an advanced approach, electromagnetic-assisted explores sealed chamber with magnetic stamp film bottom that can be reversibly actuated ...

The authors propose a real-time adaptive signal control model that aims to maintain the adaptive functionality of actuated controllers while improving the performance of traffic-actuated control systems. In this model, a flow-prediction algorithm is formulated to estimate the future vehicle arrival flow for each signal phase at the target intersection on the basis of the available signal-timing...

Gesture-changeable under-actuated (GCUA) function is presented to make robot hand grasp objects dexterously and achieve humanoid manipulations with low dependence on control system. Based on GUCA function, GCUA Hand II is developed, which has 5 fingers and 14 DOFs. All the fingers use similar tendon mechanisms to achieve GCUA function which includes traditional under-actuated (UA) grasping moti...

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...

Type Diagnosing and detecting malfunctions in internal combustion engines (ICE) is not an easy task due to their complex design. Timely high-quality ICE monitoring allows performance be maintained prevents breakdowns. Vibration acoustic analysis a powerful informative tool for faults even at early stage. This article considers method determining the main of valvetrain (VT) (tightness "valve-sea...

Trajectory of an under-actuated manipulator is usually generated according to both kinematics and dynamics of the manipulator, different to that of conventional manipulator. For this reason, another important problem in trajectory generation for the real system of an under-actuated manipulator is the realizablity of trajectory. That is, the real trajectory by real system may differ greatly from...
