摘要: The paper introduces four families of three-DOFs translational-rotational Parallel-Kinematics Mechanisms (PKMs) as well the mobility analysis such using Lie group theory. Two these are mechanisms with one-rotational two-translational degrees freedom (DOFs) and each other two has one-translational two-rotational DOFs. Four novel presented discussed representatives families. Although asymmetric, components used to realise them very similar and, hence, there is no great departure from favourable modularity parallel-kinematics mechanisms.
