Center node: "kinematic and dynamic analyses of the orthoglide 5 axis"
  Abstract: This paper deals with the kinematic and dynamic analyses of the Orthoglide 5-axis, a five-degree-of-freedom manipulator. It is derived from two manipulators: i) the Orthoglide 3-axis; a three dof translational manipulator and ii) the Agile eye; a parallel spherical wrist. First, the kinematic and dynamic models of the Orthoglide 5-axis are developed. The geometric and inertial parameters of the manipulator are determined by means of a CAD software. Then, the required motors performances are evaluated for some test trajectories. Finally, the motors are selected in the catalogue from the previous results.

Connected through hyperedge HE-1 (induced by source paper "kinematic analysis and trajectory planning of the orthoglide 5 axis"):

    - "stiffness analysis of 3 d o f overconstrained translational parallel manipulators"
    - "a six degree of freedom haptic device based on the orthoglide and a hybrid agile eye"
    - "kinematics and workspace analysis of a three axis parallel manipulator the orthoglide"
    - "kinematic analysis of a new parallel machine tool the orthoglide"
