Geometry and kinematics for a spherical-base integrated parallel mechanism (2016)
Journal Article
Sun, J., Zhang, X., Wei, G., & Dai, J. (2016). Geometry and kinematics for a spherical-base integrated parallel mechanism. Meccanica, 51(7), 1607-1621. https://doi.org/10.1007/s11012-016-0438-7

Parallel mechanisms, in general, have a rigid base and a moving platform connected by several limbs. For achieving higher mobility and dexterity, more degrees of freedom are introduced to the limbs. However, very few researchers focus on changing the... Read More about Geometry and kinematics for a spherical-base integrated parallel mechanism.
