A STUDY AND DESIGN FOR THE MANUFACTURE OF A GESTURE CONTROLLED LIFT

This project presents the study and design of a full-scale gesture-controlled lift system that integrates advanced hardware and intelligent control strategies to achieve touch-free vertical transportation. Leveraging a PAJ7620 gesture sensor and an ESP32 microcontroller, the system interprets user hand gestures to control a robust motor/pulley mechanism designed to handle loads of up to 500 kg over a lift height of 10 meters. The design incorporates rigorous load calculations, safety features including emergency braking and limit switches, and a comprehensive structural framework built from high-strength steel and aluminum. Through extensive prototype development, testing, and optimization, the system demonstrated high reliability, efficient energy use, and ease of integration within existing lift infrastructures. This innovative approach not only enhances user accessibility and safety but also paves the way for future advancements in
automated, gesture-based control systems in commercial and industrial applications.
