Abstract: The kinematic platform is a spherical-prismatic-spherical kinematic platform providing six degrees of freedom with controlled braking at each joint. The kinematic platform includes a base and an upper platform plate, with the upper platform plate having opposed upper and lower surfaces. The upper surface thereof provides a mounting surface for an external article to which controlled three-dimensional movement is to be imparted. A plurality of linear actuators are further provided, with each linear actuator having opposed upper and lower ends. A plurality of upper and lower spherical joints are provided for pivotally mounting the linear actuators between the upper platform plate and a lower base. Each spherical joint provides selective and controllable braking, allowing for the controlled rotation of each end of each linear actuator with respect to the respective upper platform plate or base.
