...Jing Li; NingHe Lu; NanYan Shen; ZeHui Ma; ZiQi Zhao The unique structural characteristics of hybrid robots, such as few degrees-of-freedom (DOF) and redundant constraints, lead to a series of challenges in the establishment of theoretical models. However, these theoretical models are indispensable...

...Wei Yue; Haitao Liu; Guangxi Li; Ke Xu This article presents a systematic approach for identifying the Cartesian stiffness of a 5-degree-of-freedom (DOF) hybrid robot for machining that includes a parallel mechanism and an A/C wrist. The novelty of this approach is that the elasticities of both...

...-solution. Based on the analysis of coupled characteristics of this mechanism, the concomitant motion neural network (NN) models of the 3-RUH R parallel mechanism and inverse position NN models of the (R(3-RUH R )/UU R P)(RRR P ) R hybrid robot are established using the Levenberg–Marquardt training...

...NanYan Shen; HengMing Yuan; Jing Li; ZiRui Wang; Liang Geng; HuiEn Shi; NingHe Lu The pose accuracy is a crucial issue that limits the application of hybrid robots. The model-free calibration instead of complex error modeling is investigated to improve the pose accuracy of a 5-degrees-of-freedom...
