Design and fabrication of an automated LED bulb replacement device

Manual LED bulb replacement poses safety risks, particularly in high-ceiling installations where ladder use increases the likelihood of falls. This project focuses on the design and fabrication of an automated LED bulb replacement device equipped with a motorized gripping mechanism enhance efficiency. The design process involved concept development, CAD modeling, material selection, and fabrication using lightweight aluminum for durability and ease of handling. Engineering analysis determined the motor torque specifications, and stability considerations for various ceiling heights. Testing validated that the device successfully removed and installed LED bulbs with the gripper ensuring a secure hold without damaging the bulb. Performance evaluation indicated smooth mechanical operation, though refinements in grip adjustability, automation response time, and improved maneuverability are recommended for future iterations. The findings demonstrate the feasibility of automated bulb replacement systems in reducing workplace hazards and providing a convenient, userfriendly alternative to traditional methods.
