Parallel robots are closed-loop mechanisms presenting very good performances in terms of
accuracy, velocity, rigidity and ability to manipulate large loads. They have been used in a …

Type synthesis of mechanisms aims to systematically determine all possible structures for a
specific mobility requirement. Numerous methods based on different theories were …

Performance evaluation is one of most important issues in the analysis and design of
parallel manipulators. As the counterparts of serial robots, parallel manipulators are mostly …

The lower-mobility parallel mechanism (PM) has fewer than six degrees of freedom (DoFs)
and requires fewer links, joints and actuators than its 6-DoF counterpart. Hence, the use of …

Abstract The Kutzbach–Grübler mobility criterion calculates the degrees of freedom of a
general mechanism. However, the criterion can break down for mechanisms with special …

The use of lower mobility parallel manipulators with less than six degrees of freedom (DOFs)
has drawn a lot of interest in the area of parallel robots. In this paper, the type synthesis of …

Efficient and precise processing of large-scale parts is an uprising problem in industry. In
this paper, a method to polish large-scale wind turbine blades using hybrid mobile robots is …

There are usually several motion patterns having the same degrees of freedom (DOF). For
example, planar motion, spherical motion, and spatial translation are motion patterns with 3 …

Origami engineering as an interdisciplinary subject brings thriving progress of mechanisms
innovation. In this paper, a construction approach from origami to multiple spherical …

Parasitic motion is a major drawback of the general 1T2R parallel mechanism (PM), where T
denotes a translation degree of freedom (DOF) and R a rotational DOF. This paper …
