Forward Kinematics and Singularity of 4‑RPR Planar Parallel Robots

Nanjing Hangkong Hangtian Daxue Xuebao
Redundant actuation can help robots overcome singular configurations， while there is no consensus on whether it can improve the motion/force transmission performance of the mechanism.

Static analysis and design of revolute joint and antiparallelogram joint: a technical report

, 2020
This technical report details the derivation of the static models of two antagonistically actuated joints: revolute (R) joint and antiparallelogram (X) joint. The conditions for these joints to possess the specified wrench-feasible workspace with the prescribed stiffness are derived.
