This paper presents the dynamic modelling and performance evaluation methodologies of a flexure-base mechanism for ultra-precision grinding operations. The mechanical design of the mechanism is briefly described. A piezoelectric actuator is used to drive the moving platform. A flexure-based structure is utilized to guide the moving platform and to provide preload for the piezoelectric actuator. By...
This paper presents a new methodology based on neural dynamics for robot path planning. The target activity is treated as an energy source injected into the neural system and is propagated through the local connectivity of neurons in the state space by neural dynamics. The elegant properties of harmonic functions are incorporated in the neural system by formulating the local connectivity of neurons...
