High-Precision Absolute Pose Sensing for Parallel Mechanisms

Sensors, 2022
A parallel mechanism’s pose is usually obtained indirectly from the active joints’ coordinates by solving the direct kinematics problem. Its accuracy mainly depends on the accuracy of the measured active joints’ coordinates, the tolerances in the active ...

3-D Visualization on Workspace of Parallel Manipulators

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2009
In parallel mechanisms, the form and volume of workspace also change variously with the attitude of a platform. This paper presents a method to search for the workspace of parallel mechanisms with 6-DOF and 3D visualization of the workspace. Workspace is
