Based on the characteristics and the common massage manipulations of Chinese medical massage, a practical series mechanical arm was presented to act the manipulations with the parallel executive mechanism. Forward kinematics was solved by the Denavit-Hartenberg transformation after the kinematics model of the arm was established. And the three-dimensional model of the arm was created by Pro/E and was imported into ADAMS for the kinematics analysis. The results indicated that the common massage manipulations could be simulated by the arm correctly and flexibly, and it verified the accuracy of the mechanism design of the arm.

Four Bar Linkage

This paper presents a design procedure to achieve a flapping wing mechanism for a micro-air vehicle that coordinates both the wing swing and wing pitch with one actuator. The mechanism combines a planar four-bar linkage with a spatial four-bar linkage attached to the input and output links forming a six-bar linkage. The planar four-bar linkage was designed to control the wing swing trajectory profile and the spatial four-bar linkage was designed to coordinate the pitch of the wing to the swing movement. Tolerance zones were specified around the accuracy points, which were then sampled to generate a number of design candidates. The result was 29 designs that achieve the desired coordination of wing swing and pitch, and a prototype was constructed.

Urban Fantasy

The philosophical views of German romantics, as well as images, motives, chronotopes characteristic of German romanticism, embodied in the domestic urban fantasy are analyzed. Special attention is paid to the techniques of the comparative method. The scientific novelty of the research lies in the almost complete absence of works devoted to the study of urban fantasy. It is noted that this fantasy subgenre has not been considered in detail in the context of the continuation of the traditions of romantic German literature. The theoretical basis of the research is presented by the works of M. M. Bakhtin, N. Ya. Berkovsky, V. M. Zhirmunsky, Yu. M. Lotman, S. S. Levochsky, etc. It was revealed that urban fantasy inherits the main images, themes, motives, symbols that dominated in German romanticism: the motive of a double, the image of a doll, an artist, etc. It was established that the authors of urban fantasy not only reproduce the image of a romantic artist-creator, but depict a character-demiurge. It has been proven that urban fantasy deepens and transforms the romantic “night beginning”: the images of the dead and vampires become plot-forming characters in independent series of works. It is concluded that the authors of urban fantasy, like German romantics, activate the readers’ attention to mythology and folklore, creating new fantastic worlds with their help.
