Abstract Synthesis of a new type of fully compliant robot mechanism was carried out by utilizing the single-open-chain theory, and the position analysis of such mechanism was simulated in ADAMS. Then the equations of up-platform's translation were formulated based on the theoretical analysis of positive kinematics. Finally, simulation on the result of theoretical analysis was conducted. The results of type synthesis and simulation showed that such mechanism could move with 3-DOF translations while without rotation. In addition, they still indicated that the No.1 and No.2 chain's positive kinematical equations are related to one driver's value each other except the No.3 chain. The kinematical simulation also proved the correctness of the theoretic results of the positive kinematical equations, which can be applied as a firm basis for the easy-operation of kinematical control for fully compliant parallel robot mechanism.
