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 …

Although the concepts of Jacobian matrix, manipulability, and condition number have
existed since the very early beginning of robotics their real significance is not always well …

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 …

This paper presents a methodology for the Jacobian analysis of limited degrees-of-freedom
(DOF) parallel manipulators. A limited-DOF parallel manipulator is a spatial parallel …

In the area of parallel robots, the use of lower-mobility parallel manipulators for many tasks
requiring fewer than six degrees of freedom (DoF) has drawn a lot of interest. This paper …

This article presents a general discussion of several aspects of our present understanding of
quantum mechanics. The emphasis is put on the very special correlations that this theory …

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 …

A new three-degrees-of-freedom (3-DOF) translational parallel manipulator (TPM) with
linear actuators, ie, 3-CRR TPM, is first proposed. The rotation singularity analysis, the …

Various 3-UPU architectures feature two rigid bodies connected to one another through
three kinematic chains (limbs) of universal–prismatic–universal (UPU) type. They were first …
