Abstract: This patent proposal document provides a complete robot hand control scheme using myoelectric intention estimation of the human being using the kernel Principal Component Analysis Algorithm (kPCA). The robot hand system includes a biometric EMG sensor system, a robot hand including with multiple fingers, a controller connected with the biometric EMG sensor system, and a robot hand. The controller acquires the biometric EMG signal by means of a biometric sensor system, estimates myoelectric motion intention by applying the kernel principal component analysis (kPCA) algorithm using a kernel function, and delivers a control command corresponding to the estimated motion intention of the user to the robot hand.

Abstract: A system and a method for controlling a robot finger may include a processor to determine a mapping function using a kernel matrix means of a multichannel electromyographic (EMG) signal to train a learning algorithm using at least one EMG signal training sample), and a storage to store data and an algorithm driven by the processor. The processor determines a kernel matrix by applying a polynomial function of the second order to the multichannel EMG signal time sample, and performs an operation for the kernel matrix and the mapping function to output a signal for controlling the robot finger.
