Linear motion is an essential mechanical property used in huge variety of applications. There are multiple ways to create linear motion, including screws, cams, pulleys, pneumatic and hydraulic actuation. Overall performance of these linear actuators can be defined in terms of cost, scale, speed, and efficiency. Current actuators are strong in one or two of these performance categories, which limits their use to specific applications.
UC Berkeley researchers have designed a novel linear actuator that is strong across all four performance categories. The clever Berkeley design provides fast and efficient actuation, and its unique structure is scalable for multiple applications. It is especially conducive to applications that have tight space confines, need a large degree of displacement at a high rate, and are cost constrained.
