Abstract: With the rapid development of smart home, people have a higher pursuit of wardrobe. Thus an intelligent wardrobe rotatable hanger with automatic access is designed for the ordinary wardrobes, which have a single storage method for high-altitude clothing grids and are very inconvenient to access clothing. Focusing on the mechanical structure design of the lifting mechanisms, robotic arms, parallel manipulators and the intelligent rotary clothes hangers, the robotic arms are strength checked in this article. Through the cooperation of intelligent rotary clothes hangers, robots that can move in multiple directions, and motor-based lifting devices, it is possible to achieve diversified storage of clothes at high altitudes and solve the problem of inconvenient clothing handling.
