“…Thus, we applied the parallel mechanism for this work. The parallel mechanism is a redesigned version of our previous structure [30]. The former version of the microhand was a 3-prismatic-revolute-spherical (PRS) parallel mechanism, while the current mechanism has a 3-prismatic-revolute-revolute (PRR) structure, which is smaller and more rigid.…”

“…The stiffness matrix of a single leaf spring can be expressed as 3 3 The stiffness of Part I is the summation of the stiffness of each limb. Therefore, the influence of each limb's mechanical parameters on the stiffness of Part I is investigated first.…”

“…Manipulators with ultrahigh precision and resolution are urgently needed and play more and more important roles in modern technology, such as atomic force microscopy, ultra precision machining, biological cell manipulation, and chip assembly in the semiconductor industry [1][2][3]. However, conventional mechanisms make it difficult to meet these requirements due to their coarse accuracies caused by inevitable backlash, friction, and joint wear.…”

“…O estudo das estruturas paralelas combinadas pode ser dividido em função da disposição das cadeias paralelas em três tipos de combinação: serial com as estruturas paralelas ligadas em sequencia (Ramadan et al, 2009;Tanev, 2006; Tanikawa et al, 1995;1996;Wu et al, 2008;Zheng et al, 2004;Yabugaki et al, 2013); ligação em paralelo das cadeias paralelas (Yoon e Ryu, 2005); e misto que é a combinação de estruturas paralelas superpostas em série e paralelo (Badescu e Mavroidis, 2004;Badescu et al, 2002).…”

“…Estas estruturas serão denominadas neste trabalho de estruturas paralelas combinadas. Estas estruturas podem superar o problema do espaço de trabalho limitado, e fornecerem vantagens tanto das estruturas serial quanto paralela (Zheng et al, 2004;Zhao et al, 2009).O estudo das estruturas paralelas combinadas pode ser dividido em função da disposição das cadeias paralelas em três tipos de combinação: serial com as estruturas paralelas ligadas em sequencia (Ramadan et al, 2009;Tanev, 2006; Tanikawa et al, 1995;1996;Wu et al, 2008;Zheng et al, 2004;Yabugaki et al, 2013); ligação em paralelo das cadeias paralelas (Yoon e Ryu, 2005); e misto que é a combinação de estruturas paralelas superpostas em série e paralelo (Badescu e Mavroidis, 2004;Badescu et al, 2002).As diversas estruturas híbridas propostas na literatura apresentam vantagem de expandir o espaço de trabalho da estrutura paralela podendo também aumentar a sua acuracidade e rigidez. Estas são utilizadas com a capacidade de se…”
