Abstract

This paper presents how it is effective to use many features for improving the accuracy of the visual servoing control for humanoid robot. Some rank conditions, which relate the image Jacobian, and the control performance are derived. It is also proven that the accuracy is improved by increasing the number of features. Effectiveness of the redundant features is verified by the real time experiments on a Dual-Arm Robot manipulator system. [ABSTRACT FROM PUBLISHER]

Abstract

In general, it is possible to estimate the noise by using information on the robot's own motions and postures, because a type of motion and gesture produces almost the same pattern of noise every time. In this paper, we describe an voice recognition control system for robot(VRCS) system which can robustly recognize voice by adults and children in noisy environments. We evaluate the VRCS system in a communication robot placed in a real noisy environment. Voice is captured using a wireless microphone. To suppress interference and noise and to attenuate reverberation, we implemented a multi-channel system consisting of an outlier-robust generalized side-lobe canceller technique and a feature-space noise suppression using MMSE criteria. Voice activity periods are detected using GMM-based end-point detection. [ABSTRACT FROM PUBLISHER]
