Automated gate systems have become essential in modern residential security due to the need for controlled access and reduced manual operation. Traditional manually operated gates often pose safety risks, increase security vulnerabilities, and require physical effort from users. This project presents the virtual design and simulation of an automated residential sliding gate using SolidWorks for mechanical modeling and Proteus for electronic control simulation. The system integrates key mechanical components such as the gate frame, rollers, track, and rack-and-pinion mechanism, alongside a microcontroller-based control circuit designed to operate the motor responsible for gate movement. The SolidWorks simulation was used to analyze the gate’s mechanical performance, focusing on linear motion, component alignment, and the conversion of rotational motor input into smooth sliding action. Proteus was employed to simulate the automation logic, including motor activation, direction control, and stopping at predefined limits. These simulations allowed full validation of system behavior without physical prototyping, reducing cost and eliminating real- world testing constraints. Results from both platforms confirmed that the gate moves smoothly, responds correctly to control inputs, and maintains proper synchronization between mechanical and electronic subsystems. The study demonstrates that virtual simulation tools provide an effective method for evaluating automated gate mechanisms before fabrication. The design also offers a foundation for future enhancements such as remote wireless control, improved safety features, and integration with smart-home systems.
