This study investigates the feasibility of adopting the 2-DOF motion platform design to combine optimal workspace and mechanical advantage, which is considered as important for low-cost simulators. A design method to optimize an objective function is presented. This method consolidates some major issues related to workspace volume, workspace symmetry, and actuator power requirements. Performance indices obtained from the inverse/forward kinematics are adopted within a global optimization procedure, GA, to determine the design spread-angle that improves the static and dynamic performance.
