This article studies the kinematic characteristics of Schatz 6R 6R-Bennett 4R hybrid mechanism, which is combined by the Bennett 4R mechanism and Schatz 6Rmechanism. In the preliminary analysis, a constant-velocity input is specified and then modify the link-twist parameters of Bennett 4R loop to verify the variations of joint and link angular accelerations in the Schatz 6Rmechanism. In the beginning, Inventor software is conducted to construct and design the 3D model and size of mechanism. Then, the angular velocities and accelerations of joints and coupler links are analyzed by use of the simulation CAE built in the Inventor CAD software. In addition, Excel software is used to arrange data and graph of simulated results. The results show that, in spite of increasing angular accelerations with the higher link-twists in the Bennett 4R loop, the period of keeping the flatness of angular acceleration in Schatz 6R loop are increased too. In the future, other structural parameters will be changed to utilize the distinct types of Bennett 4R loops, or to actuate the variable input driver to improve the kinematic characteristics of the proposed Schatz 6R-Bennett 4R hybrid mechanism.
