This study proposed the ultra-wideband(UWB) sensor to detect the vibration of the delta robot and the distance between UWB sensor and robot arm. Based on the radar propagating principle and the proposed algorithm, the vibration status of robot arm can be obtained. Besides, the vibration status can be reduced by feedback the information to the controller of the robot arm. The advantage of the proposed...
In the present study, we have examined sulfation of cerium oxide via impregnation of (NH 4 ) 2 SO 4 , followed by heating in the temperature range of 220–720°C, using Raman Spectroscopy. Based on the SO and SO stretching frequencies in the range of 900–1400 cm −1 , a wide range of surface oxysulfur species and bulk cerium-oxy-sulfur species are identified. At 220°C,...
