An accurate dynamic model is a prerequisite for realizing precise control of industrial robots. The dynamics research multi-degree freedom (DOF) robots relatively unexplored and needs to be solved urgently. In this paper, modeling method multibody system 6-DOF robot proposed based on the screw theory. established has more concise unified mathematical form, modular matrix expression convenient robot. order ensure that suitable motion in wide range angles, quaternions are used as generalized...

Eleven leptonetid species belonging to four genera collected in Jiangxi and Fujian Provinces, China are presented. Ten new of midget cave spiders from southern diagnosed, described, illustrated: Leptonetela dawu Yao & Liu, sp. nov. , L. yuanhaoi zuojiashanensis Jiangxi; Longileptoneta guadunensis huboliao jiaxiani letuensis renzhouensis tianmenensis Pararana mingxuani Fujian. Furthermore, Falcileptoneta monodactyla (Yin, Wang Wang, 1984) is recorded province for the first time....

When one joint of a manipulator fails and is locked, the velocities remaining joints will produce sudden change. The change velocity in fault tolerant operation two coordinating manipulators for locked failures studied. First, difference between original that reduced defined as velocity. Then, corresponding planning algorithm based on this index proposed. At last, numerical solid simulations operations spatial 4R are implemented. Simulation results show initial postures heavily affect...

At present, the absolute positioning accuracy and control of industrial serial robots need to be improved meet requirements precision manufacturing precise control. An accurate dynamic model is an important theoretical basis for solving this problem, parameters are prerequisite The research dynamics parameter identification can greatly promote application in field automation. In paper, we study dynamical modeling robot system with six rotational DOF (6R system) propose a new method...

Collections of thomisid spiders by amateur and professional arachnologists in China have led to the discovery some interesting crab (Thomisidae). Two new species two genera are described illustrated with photographs SEMs: Phartaxizang Liu & Yao, sp. nov. (♀) Stephanopisqiong (♀). The previously unknown males Borboropactuslongidens Tang Li, 2010 Stephanopisxiangzhouica Liu, 2022 were also collected for first time. genus Borboropactus Simon, 1884 is reported time from Vietnam. Stephanopis...

Taxonomic notes on the Talaus species from China are provided. Two new species, T. yuyang Yao & Liu, sp. nov. and zhangjiangkou described illustrated, a further three redescribed based their genitalic characters: dulongjiang Tang, Yin, Ubick Peng, 2008, niger sulcus Tang Li, 2010. The xiphosus Zhu Ono, 2007 is considered junior synonym of triangulifer Simon, 1886 an examination many recently collected female male specimens Guangxi Province, China. Diagnoses, detailed illustrations map...

This paper proposes a kinetostatic approach for analyzing the joint torques of redundant snake robot. The method is suitable weightless space environments. With high degree freedom and flexible cable actuation, robot well-suited utilization in space-weightless reduces computational cost by using multiplication matrices vectors instead inverse matrices. Taking advantage velocity screw (twist) force (wrench), this strategy provides an idea serial robots to achieve calculation torques....

Although there have been many recent taxonomic revisions and large-scale faunistic surveys focusing on spiders from Jiangxi Province, taxa still remain unknown, such as the Anyphaenidae spiders. Therefore, none of anyphaenid species has recorded this Province.

Three species of the spider family Philodromidae are reported from south China. A new genus, Sinodromus gen. nov. , is described Jiangxi, Fujian, and Hunan Provinces. It can be distinguished other genera by tegular apophysis palp cymbial process, as well its uniquely striped abdomen. The type species, S. fujianensis sp. a second perbrevis illustrated; these occur in bamboo forests hilly areas. Additionally, female Philodromus guiyang Long & Yu, 2022 for first time Jiangxi All illustrated...

Four new species of the family Liocranidae are described from China and Vietnam. The genus Sinocranumgen. nov., is erected to accommodate S.menghaisp. nov. (♂♀) China. Further include Koppeningersp. (♀) China, Xanthariabaizilongisp. X.cucphuongsp. (♂) In addition, Xantharia transferred Miturgidae Liocranidae. Koppe reported Vietnam, respectively, for first time.

Annulus-shaped compliant pivot, formed by well-proportioned modules between the outer ring and inner ring, can be employed in precision mechanical systems due to good performances. Especially for multi-series leaves one module, annulus-shaped pivot fulfill a large displacement range without any axial drift theory. In design of load–displacement behavior stress analysis with analytical forms are important consideration. However, literature, there is few detailed work. this article, general...

Aiming at the problem that absolute positioning accuracy of industrial robots cannot meet requirements high-precision positioning, a comprehensive compensation method based on back propagation (BP) neural network was proposed, which considers both geometric parameters factors and stiffness performance influencing robots. This uses actual coordinates evaluation index an robot as input, theoretical output to train BP network. Then trained is used compensate robot. tested KUKA KR500L340-2...
