Tsien meticulously broke down the mechanics of servomechanisms—automatic devices that use error-sensing feedback to correct the performance of a mechanism. This laid the direct groundwork for modern robotics, computer numerical control (CNC) machining, and automated assembly lines.
Tsien defined "Engineering Cybernetics" as a field aimed at organizing and summarizing design principles for controlled or guided systems. Its primary goals include: engineering cybernetics tsien pdf top
