The Development of Semi – Automatic Transportable Stick Led Bulb Replacer with a Center Bulb Sensor aims to help maintenance workers, elderly individuals, and individuals with disabilities. The prototype is time and labor- efficient, cost-saving, and physical strain. The prototype can save farmers money by reducing the need for manual labor. The Semi – Automatic Transportable Stick Led Bulb Replacer with a Center Bulb Sensor designed with 4 special features such as Toggle switch controller, Laser center bulb sensor, Adjustable aluminum square tube, and DC gear motor. The prototype was evaluated by 50 respondents composed of homeowners, faculty members, and welding students. The prototype was evaluated by the performance of the developed prototype based on the 5 criteria namely, functionality, workability, safety, aesthetics, and economy. The evaluation resulted in an overall mean of 4.55 with a descriptive rating of “Highly Acceptable.” Based on the evaluation and findings, the project study can help the maintenance workers, elderly individuals, and individuals with disabilities, as the device reduces the risk of falls and electrical hazards

The traditional method of Pole Light Bulb Changer is usually practiced as a method for
replacing bulbs. However, it is tedious, time-consuming, and requires more labor and an
incredible amount of patience. Also, the laborers can suffer from back problems such as
muscle strains, sprains, nerve irritation, or underlying conditions like arthritis or slipped
discs (health risks) and electrified (electric hazard). The project study focused on design,
fabrication, testing, and evaluation. The Development of Semi – Automatic Transportable
Stick Led Bulb Replacer with a Center Bulb Sensor aims to help maintenance workers,

elderly individuals, and individuals with disabilities. The prototype is time and labor-
efficient, cost-saving, and physical strain. The prototype can save farmers money by

reducing the need for manual labor. The Semi – Automatic Transportable Stick Led Bulb
Replacer with a Center Bulb Sensor designed with 4 special features such as Toggle switch
controller, Laser center bulb sensor, Adjustable aluminum square tube, and DC gear motor.
The prototype was evaluated by 50 respondents composed of homeowners, faculty
members, and welding students. The prototype was evaluated by the performance of the
developed prototype based on the 5 criteria namely, functionality, workability, safety,
aesthetics, and economy. The evaluation resulted in an overall mean of 4.55 with a
descriptive rating of “Highly Acceptable.” Based on the evaluation and findings, the project
study can help the maintenance workers, elderly individuals, and individuals with
disabilities, as the device reduces the risk of falls and electrical hazards
