Enhanced Kinematic Calibration of a 4PPa-2PaR Parallel Manipulator with Subchains

IROS 2025

This paper proposes an innovative virtual chain-based kinematic calibration for the 4PPa-2PaR parallel manipulators with subchain architectures. Conventional calibration methods for such architectures suffer from inherent limitations due to coupled parameter constraints and restricted solution space

Design and Modeling of a Compound Twisted and Coiled Actuator Based on Spandex Fibers and an SMA Skeleton

RA-L 2022

Twisted and Coiled Actuators (TCAs) are a class of new artificial muscles for flexible actuations. However, conventional TCAs based on nylon fibers commonly require high driving temperature, which limits their applications. Although the TCAs based on spandex fibers can produce high strain under low

Kinematic design of a novel 4-DOF parallel manipulator

ICRA 2017poster

A new four degrees-of-freedom (DOF) parallel manipulator that can produce 3-DOF translations and 1-DOF rotation (3T1R), has been proposed in this paper. It has two identical limbs connected to the moving platform through passive revolute joints, and each limb has two identical branches driven by a p…
