Serial kinematic designs have advantages when it comes to cost and simplicity, and work very well for most standard applications. In a multi-axis serial kinematics system, each actuator (and usually each sensor) is assigned to exactly one degree of freedom. Serial Kinematics for Lower Cost / Standard Applications They are vacuum compatible, operate over a wide temperature range, and require neither lubricants nor compressed air for operation. Flexures are maintenance free and not subject to wear. Friction and stiction are entirely eliminated, and flexures exhibit high stiffness, load capacity, and resistance to shock and vibration. With the use of flexure guides and mechanical levers, the motion of a piezo stack can be multiplied (up to 100’s of microns or even a few mm) and guided at the same time. Flexure motion is based on the elastic deformation (flexing) of a solid material.
