An enhanced kinematic model for calibration of robotic machining systems with parallelogram mechanisms

J Peng, Y Ding, G Zhang, H Ding - Robotics and Computer-Integrated …, 2019 - Elsevier
Kinematic calibration presents an efficient way to improve the absolute accuracy of robotic
machining systems with parallelogram mechanisms. However, the mixed chain structure, ie …

Kinematic and dynamic analysis of a 4-DOF over-constraint parallel driving mechanism with planar sub-closed chains

Y Huang, J Zhang, X Xiong, S Liu - Robotica, 2023 - cambridge.org
In this paper, a new over-constrained parallel driving mechanism (PDM) with planar sub-
closed chains is proposed. First, the number of over-constraints on the PDM is calculated …
