84555209 Robots have proven the benefits of patterns on fingers
The patterns on their fingertips to help define the shape of touch with objects. That is the conclusion drawn by researchers modeled the patterns on the robotic sensor. The work of researchers have not yet been accepted for publication in a peer-reviewed journal, but its preprint available at arXiv.org. The grooves and furrows on the fingers of help to better carry out the seizure of objects and feel their texture, increasing the amount of information extracted by touching objects. Authors of new work decided to check whether the patterns similar function in robots – for this they developed a special sensitive sensor. Created by scientists unit is a square plate the size of four square millimeter, which housed four sensors that respond to the pressing force. Top specialists have placed a transparent plastic coating is smooth, and the last layer is a plastic plate with the grooves. With the resulting device researchers touched various objects, identifying changes in the readings of power presses. After analyzing the testimony of his instrument, the researchers concluded that it is possible to determine the shape of objects to which touches. In particular, the sensor readings allowed a clear distinction between flat and round objects. The new findings may prove useful for the creation of new mechanical devices – at the present time, developers tend to unload their most CPUs and shift the various "minor " problem (like determining the shape of objects) directly on the effectors – for example, at the fingertips of robots.
