Electrical activity is generated in the forearm muscles during muscular contractions that control dexterous movements of a human finger and thumb. Using this electrical as an input to train neural network for purposes classifying not straightforward. Low cost wearable sensors i.e., Myo Gesture armband (www.bynorth.com), generally have lower sampling rate when compared with medical grade EMG det...

This paper presents the results of a comprehensive study on the efficiency of planar parallel mechanisms, considering their kinetostatic performance and also, their workspace. This aim is approached upon proceeding single- and multi-objective optimization procedures. Kinetostatic performances of ten different planar parallel mechanisms are analyzed by resorting to a recent index, kinematic sens...

This paper presents a novel method to solve the inverse kinematics of redundant manipulators with active Spherical ball joint. The workspace density function is built combining the Fourier transform, convolution theorem and particular form of the workspace density of a single link, which can accurately generate the size of workspace. The approach of inverse kinematics selects a solution from am...
