Abstract: We have developed a universal robot hand with tactile and other sensors. An array-type tactile sensor is crucial for dexterous manipulation of objects using a robotic hand, since this sensor can measure the pressure distribution on finger pads. The sensor has a very high resolution, and the shape of a grasped object can be classified by using this sensor. The more the number of measurement points provided, the higher the accuracy of the classification, but with a corresponding lengthening of the measurement cy… Show more

“…It was previously investigated that the resolution on the fingertips should be as high as 1mm since the fingertips are mostly involved in fine manipulation [29]. In the current state of the art, fingertip tactile sensors integrated with robot hands have a spatial resolution of around 5mm [34], [35]. On less sensitive parts of a robot hand like the palm, the spatial resolution decreases up to 5mm as stated in [17].…”

“…Figure 1(b) shows the structure of conductive rubber at nano-scale level [48]. Sensors based on conductive rubber with multilayer structures as in [49], [39], [35], [54] (Figure 1(c), 1(d)) may suffer from delamination of top layers. This can be avoided by using a single layer of the conductive rubber with a stitched array of wires in orthogonal orientations as in [55].…”
