Abstract: In this paper a neural identification approach is used to estimate the parameters of a mobile robot with nonholonomic constraints. Then an inverse optimal control is designed for its control. In order to take in account the environment of the robot, a monocular visual sensor is mounted on the robot to estimate the velocities for the controller. Simulations results show the effectiveness of the proposed neural controller.

Luna-Rosas, F.J.",,"2012",,"This work aims to design a filter to attenuate high- and medium- frequency noise in optical test images without changing the edges and original characteristics of the test image, generated by traditional filters (spatial or frequential). The noise produced by the LCD pixels (used as a diffraction grating in the Ronchi test) was analyzed. The diffraction is modulated by the spherical wavefront of the mirror under test, generating at least two frequency band noise levels. To reduce this bi-frequential noise, we propose to use an array of filters with the following structure: a low-pass frequential filter LPFF, a band- pass frequential filter BPFF and a circular mask spatial filter CMSF; thus obtaining the composed filter CF=LPFF-(BPFF)(CMSF). Various sizes of filters were used to compare their signal-to-noise ratio against simple filters (low-pass and band-stop). " 2012 SPIE.
