This paper presents a novel visual servoing strategy for a nonholonomic mobile robot, which is based on a new motion estimation technique. By taking into account the planar motion constraint of mobile robots, the proposed motion estimation technique does not require the estimation and decomposition of the homography or fundamental matrix, and it dose not cause any ambiguity problems. Moreover, the...
Piezoelectric actuators have been widely utilized in micro/nano systems due to the high positioning resolution. A typical instance is piezo-scanners equipped in scanning probe microscopes (SPM) to implement nanoscale measurement and manipulation for various samples. However, the inherent hysteresis and structural vibration of a piezo-scanner largely limit its positioning accuracy and bandwidth, as...
