High-Precision Absolute Pose Sensing for Parallel Mechanisms [PDF]

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 ...
