This project involved designing and building a scissor linkage system driven by a gear train and rack-and-pinion mechanism. The scissor linkage featured one fixed bottom leg while the other was affixed to the rack, which propelled the vertical motion of the assembly.
Motor rotation is translated into linear movement through a gear-driven rack. As the rack moves, it drives one leg of the scissor linkage while the opposite leg remains fixed — converting rotational input into controlled, repeatable vertical extension.
A limit switch provides positional reset, ensuring the system can return to a known home position reliably. The entire system is controlled via a Raspberry Pi and L298N motor driver.
