        abstract = {With the growing demand for reusable spaceflight technologies, the safe and efficient landing of rocket boosters has become a critical area of focus in aerospace engineering. This project presents the design and development of a scaled-down autonomous landing gear deployment model inspired by real-world systems used by organizations such as SpaceX and Blue Origin [1],[5]. The system employs an Arduino Uno microcontroller interfaced with an ultrasonic sensor to detect descent height and trigger servo motor-driven leg deployment at a specified altitude. The landing gear comprises a combination of main and supporting legs, integrated with mechanical springs to absorb impact forces and enhance stability during landing. The model was validated through a series of component-level and system-level tests. This prototype provides foundational insights into the dynamics of small-scale autonomous landing systems and can be further enhanced with features such as hydraulic dampers and thrust vectoring.},
